1 - DESCRIPTION

1.1 - GENERAL

1.1.1 - PRESENTATION

The “JET-POWER FILTER II” is a static GPU designed to provide

ground power for maintenance and startup of aircraft having 28 VDC

electrical systems.

The “JET-POWER FILTER II” changes alternating current at its input

to a continuous current of 28V (adjustable on panel) by using its trans-

former and six-phase rectification. Therefore when electric energy is

available to supply the GPU it can substitutes external batteries or/and

GPU equipped with diesel engine.

The “JET-POWER FILTER II” provides pure output tension with ex-

tremely low ripple (0.035% at 100A), even under normal load, causing

no interference with aircraft equipments.

Due to its transformer and oversized rectifier the regulation is excellent

and provides protection against short circuit, over current, overvoltage

and phase failure.

The “JET-POWER FILTER II” has been resized especially for

MANUFACTURER to be used in extreme conditions (24 hours work-

ing) providing power to mounting equipments on an aircraft during

stages of assembly and electronics testing.

It is equipped with a second output cable of 28 and 24 VDC,to substitute

aircraft´s battery, being able to reduce 09 volts on its output voltage rel-

ative to the first output by setting its selector switch on position “7”.

1.1.2.1 - INPUT:

220V (Brazil);

208V (USA);

Three-phase, no phase sequence.

NOTE: The neutral of “JET-POWER FILTER II” is the BLUE cable.

1.1.2.2 - 1st OUTPUT (Plug for Output Source)

It is located on the left front side, coming directly from inside the source,

providing 24 to 33 VDC, depending on how the seven position switch

(front panel) is set.

1.1.2.3 - 2nd e 3rd OUTPUT (28 and 24V to substitute aircraft´s battery)

They are two gray connectors, placed at the front center, to be used with

one cable, connected on the left to provide tension and current equal to

the first output (28 V), or connected on the right to provide 09 volts less

than the first output. When giving 33 volts it will provide 24 volts (up

to 10A, protects against overload). The cable to be connected to these

outputs is loose, with a gray connector, with length as ordered (5 or 10

m). In order to avoid accidental disconnection lock it by using the at-

tached pin.

1.1.2.4 - MAXIMUM CURRENT:

2,000A at peak (supply capacity);

600A continuous (28V output).

NOTE: The current delivered by “JET-POWER FILTER II” at the start,

or during equipment tests, depends on the turbine kind or the applied

load.

1.2.2 - CONTROL PANEL (UPPER PANEL)

1.2.2.1 - SWITCH FOR ADJUSTMENT OF THE OUTPUT TENSION

(PN 28.01.1150)

It sets the output tension from 24 to 33VDC.

1.2.2.2 - SWITCH FOR ADJUSTMENT OF THE OUTPUT CURRENT

LIMITER (PN 28.01.1122)

Placed on the right side of the panel, it must be used to set the maximum

current allowed on the aircraft in which it is connected. The accuracy

of this setting is around 5%.

The current limit is taken by a complete disconnection of the output

current after 1 second exceeding the set value.

Never place the current limiter knob in range below that demanded by

the load necessary for maintenance or during starts to avoid cuts during

the maintenance or at the start. Please check the aircraft manual to know

about its maximum current demanded.

ATTENTION:

The setting above the maximum current range allowed by the aircraft

does not mean that the current will come to this value in normal condi-

tions, even at the start.

Under normal conditions the GPU will deliver only the current de-

manded by the aircraft.
