1.0 SCOPE OF MANUAL

This manual is provided to assist the user in the installation and operation of the Bertan

Series 602C, 603C, 605C, 606C and 612C modular high voltage power supplies. Statements

will apply to models in all of the Series unless reference is made to specific models. For the

protection of personnel and equipment, it is essential that this manual be thoroughly read

prior to the installation and application of power.

1.1 PURPOSE OF EQUIPMENT

The Series 602C, 603C, 605C, 606C and 612C are families of regulated fixed output polarity

modular high voltage power supplies. They provide exceptional performance in applications

such as CRT’s spectrometers, detectors, medical imaging, image intensifiers, E-Beam, I-

Beam, medical imaging and capillary electrophoresis (HPCE) systems.

1.2 DESCRIPTION

The units are fully enclosed and designed to easily satisfy system or bench top operation. A

wide range of stable output voltages, up to 30kV are available. The output voltage is

controlled locally by a minimum 15-turn potentiometer. Remote analog voltage of resistance

programming is also available to the user as a standard feature. All units offer a 0 to +5Vdc

analog monitor output proportional to the output current.

The Series 602C, 603C and 612C require an input of 115/230Vac (switch selectable) +10%,

50-60Hz. The Series 605C and 606C require a +28Vdc +10% input (or +24Vdc ±10% for

units equipped with +24V Option). Each unit in the Series converts the applied power to a

high voltage DC output. This output voltage is highly regulated and filtered. The high voltage

assembly is fully encapsulated in silicone rubber for reliable, arc-free, stable operation.

SECTION II – OPERATION

CAUTION: THIS UNIT CAN STORE HAZARDOUS VOLTAGE! COMPLETELY DISCHARGE

THE HIGH VOLTAGE TO GROUND BEFORE ATTEMPTING REMOVAL OF THE

HIGH VOLTAGE CABLE.

2.1 INSTALLATION

All power supplies can be mounted in any position using the tapped holes in the base plate.

The mounting screws should extend no more than ¼” into the unit. Series 602C and 605C

require #8-32 mounting screws. Series 603C, 606C, and 612C require #10-32 mounting

screws.

2.2 INPUT POWER

Input power is applied via the 3-terminal terminal strip for the Series 602C, 603C, and 612C or

via the 9-pin connector for the Series 605C and 606C. The terminal or pin connections are as

listed in Section 2.7.

CAUTION: APPLICATION OF INPUT POWER CAN IMMEDIATELY PRODUCE A HIGH

VOLTAGE OUTPUT!

2.3 HIGH VOLTAGE CONTROL

There are three modes of controlling the high voltage. The use can select mode by making

appropriate connections via the 9-pin Molex connector. All modes provide high voltage control

from 0 to 100% (±0.5%).

2.3.1 INTERNAL POTENTIOMETER CONTROL

See Section 2.7 for hook-up information. This will allow control of the high voltage output by

means of the multi-turn potentiometer accessible via a hole in the cover.

2.3.2 EXTERNAL POTENTIOIMETER CONTROL

See Section 2.7 for hook-up information. Connecting an external potentiometer

(recommended value of 5kΩ) will control the high voltage output independently of the internal

potentiometer setting.

2.3.3 EXTERNAL VOLTAGE CONTROL

See Section 2.7 for hook-up information. The output high voltage can be controlled by a 0 to

+5Vdc analog signal.

2.4 HIGH VOLTAGE MONITOR

See Section 2.7 for hook-up information. A 0 to +5Vdc analog signal which is proportional to

the output high voltage. The monitor has a series impedance of 10kΩ.

2.5 OUTPUT CURRENT MONITOR

See Section 2.7 for hook-up information. A 0 to +5Vdc analog signal which is proportional to

the output current. The monitor has a series impedance of 10kΩ.

2.6 TRIP UNIT

See Section 2.7 for hook-up information. Provides the user with a means of remote turn

ON/OFF. This input requires a contact closure to ground to turn off the high voltage. An NPN

open collector transistor logic can also be employed. When no connection is made to this

input the high voltage is enabled.

SECTION III PROGRAMMING OPTIONS

3.1 GENERAL

To provide additional flexibility and compatibility with earlier models, provision has been

included to allow voltage programming of all models with a 0 to –5 Volt programming input.

There are four different jumper-selectable modes for programming. The jumpers for selecting

the required operating mode are located on PCB100 (the large PCB), easily accessible upon

removal of the cover. Jumper locations are shown below in Table III-1.

The four modes are described below. The first three modes apply to all Series 602C, 603C,

605C, 606C and 612C units. The last mode applies only to the Series 612C and is included

only with Series 612C units ordered with the –5VPRO option.

3.2 STANDARD MODE

The unit is shipped in this configuration and operation is as described in the previous sections

of this instruction manual. The unit can be controlled using the internal pot or programmed

with a remote 0 to +5 Volt signal or controlled with a remote potentiometer.

3.3 -5 VOLT PROGRAMMING (for 0 to 100% output voltage) MODE

To achieve this operation the jumpers on PCB100 must be configured as shown in the chart

below. In this mode the programming signal is applied to P2 pin 4, same as for Standard

Mode, only now a 0 to –5 Volt programming input is required to achieve 0 to 100% output

voltage programming. No jumpers should be attached to P2, the external connector. In this

mode there is no internal control, the internal potentiometer is bypassed.

3.4 -5 VOLT PROGRAMMING (for 0 to 103% output voltage) MODE:

To achieve this operation the jumpers on PCB100 must be configured as shown in the chart

below. In this mode the programming signal is applied to P2 pin 4, same as for Standard

Mode. No jumpers should be attached to P2, the external connector.

In this mode the internal potentiometer is used to control the maximum programmed output

voltage at –5 Volt programming input. With the potentiometer fully clockwise, the output will be

0 to 103% of maximum for a 0 to –5 Volt input. With the potentiometer turned up

approximately half way, a 0 to –5 Volt input will produce a 0 to approximately 50% of maximum

output voltage.

This mode is included to provide exact compatibility with some previous units. It also provides

the user with a controllable upper limit on the programmed output for an input of –5 Volts.

3.5 SERIES 612C –5 VOLT PROGRAMMING MODE

Series 612C units ordered with the –5VPRO (-5 Volt Programming) option, include an extra 5

pin hexaganol connector (J3). The connector contains additional monitor outputs and a 0 to –

5 Volt programming input. This option provides compatibility with earlier Series 612C models

when used with –5 Volt programming. The mating connector for J3 is included and J3

connections are shown below in Table III-2.

In this mode the programming signal is applied to J3 pin A. A 0 to –5Volt programming input is

required to achieve 0 to 100% output voltage programming. No jumpers should be attached to

P2, the external connector. In this mode there is no internal control, the internal potentiometer

is bypassed.

SECTION IV – CIRCUIT DESCRIPTION

4.1 FUNCTIONAL DESCRIPTION

The 602C, 603C, and 612C employ a standard stepdown transformer to obtain a nominal

+28Vdc from the input ac power. The Series 605C and 606C obtain +28Vdc (+24Vdc for +24V

Option models) from the input ac power. The circuit converts the +Vdc low voltage input

DC power to a high voltage DC output. This output voltage is highly regulated and filtered

and can be varied either by the local potentiometer control or through the REMOTE

PROGRAM input.

An oscillator determines the frequency (approximately 20kHz) at which all amplification, high

voltage transformation, rectification and filtering occurs. The amplification is a function of a

control voltage which performs the function of control and regulation. A sample of the output

voltage is compared against a reference voltage in the sensing circuit. The sensing circuit

generates the control voltage to set and maintain a fixed high voltage output.

The encapsulated high voltage assembly includes a high voltage power transformer, rectifier or

multiplier circuits, ripple filter and sensing circuits. These are all critical, custom designed and

encapsulated components.

SECTION V – MAINTENANCE

5.1 GENERAL

The high voltage power supply should not require any maintenance or calibration. It is

designed for reliable, trouble free operation. If any question should arise, contact the Bertan

Customer Service Department for assistance or return authorization. Although it is felt

that adequate information is provided in this manual, it is suggested that the unit be returned

to the factory is service should become necessary.

The power supply can be returned to the factory for annual calibration and certification to its

original specification. For traceability, a certificate will be issued, indentifying the serial number

of the unit calibrated and all test equipment used to perform the calibration. All measurements

are traceable to the National Institute of Standards and Technology (N.I.S.T.). Contact the

factory for additional details.

5.2 CLEANING

Cleaning of the power supply shouldonly be performed with the supply disconnected from the

ac power source. A soft cloth moistened with conventional ammonia-based cleaning agents

will suffice for all exposed surfaces. The exposed shell of the HV connector should be cleaned

with isopropyl alcohol.

If the supply is operated in a dusty environment, an accumulation of dust/debris may build-up

inside the unit which may cause noisy operation (i.e., “ticking” or minor crackling) in the area of

the HV cabling on the 10kV through 30kV models. The safest way to remove such debris is

with compressed air. Ensure that no dust/debris is left behind in the insulative medium of the

HV output connector after this cleaning operation. Such dust may be removed with a cotton

swab moistened with isopropyl alcohol.
