Terminology and

Abbreviations

All values in this document are typical values under the following conditions

unless otherwise noted: 230V AC 50 Hz input voltage, 24V 2.5 A output load,

25 °C (77 °F) ambient temperature, and after a 5 minutes run-in time.

Product Overview The 1606-XLB60EH is a DIN rail mountable single-phase input power supply,

which provides a floating, stabilized, and galvanically separated SELV/PELV/

ES1 output voltage.

The output fulfills the requirements for a limited power source according to

NEC CLASS 2.

The device is equipped with push-in terminals, which are optimized for

automated wiring. The mechanically robust housing is made of a high-grade,

reinforced molded material, which permits surrounding temperatures up to

70 °C (158 °F).

The unit is designed as “Class of Protection” II unit and fulfills the safety and

electromagnetic compatibility (EMC) requirements without an input PE

connection. This saves wiring costs.

The 1606-XLB60EH is part of a series of compact, industrial grade DIN rail

power supplies. This series focuses on the essential features that are needed in

present day industrial applications. The excellent cost/performance ratio does

not compromise quality or reliability.

Product features:

•100…240Vwide-rangeinput

• NEC CLASS 2 compliant

• Cost-optimized without compromising quality or reliability

• No PE connection required

• Width only 36 mm (1.42 in.)

• Efficiency up to 91.8%

• Low no-load power losses

• Full power between -10…+60 °C (14…140 °F)

• Push-in terminals

Terms Descriptions

PE The abbreviation for Protective Earth. PE has the same meaning as the symbol.

The symbol for Protective Earth.

Earth, Ground This document uses the term “earth” which is the same as the U.S. term “ground”.

AC 230V A value that is displayed with the AC or DC before the value represents a nominal

voltage with standard tolerances (usually ±15%) included. For example, DC 12V

describes a 12V battery disregarding whether it is full (13.7V) or flat (10V).

230V AC A value with the unit (V AC) at the end is a momentary value without any additional

tolerances included.

50 Hz versus 60 Hz As long as not otherwise stated, AC 100V and AC 230V parameters are valid at 50 Hz

mains frequency. AC 120V parameters are valid for 60 Hz mains frequency.

nom Indicates a nominal value.

typ Indicates a typical value.

— (alone in table cell) A dash alone in a table cell indicates that there is no information to be included in that

cell.

Input Inrush Current An NTC limits the input inrush current after turn-on of the input voltage. The

inrush current is input voltage and ambient temperature dependent. The

output load has no impact on the inrush current value.

The charging current into EMI suppression capacitors is disregarded in the

first microseconds after switch-on.

Output The output provides a SELV/PELV/ES1 rated voltage, which is galvanically

isolated from the input voltage.

The output is electronically protected against no-load, overload, and short

circuit. If there is a protection event, audible noise may occur.

The output is designed to supply any kind of loads, including inductive and

capacitive loads. Capacitive loads should not be larger than 2500 μF with 2.5 A

or 5000 μF with 1.25 A additional current load.

At heavy overloads (when output voltage falls below 14V), the power supply

delivers continuous output current for 25 ms. After this, the output is switched

off for approximately 145 ms before a new start attempt is automatically

performed. This cycle is repeated as long as the overload exists. If the overload

has been cleared, the device operates normally.

Hold-up Time The hold-up time is the time during which the output voltage of a power supply

remains within specification following the loss of input power. The hold-up

time is output load dependent. At no load, the hold-up time can be up to

several seconds. The green DC OK status indicator is also on during this time.
