Switching Frequencies

The power supply has three converters with three different switching frequencies

included. Two are nearly constant. The other one is input voltage and load dependent.

Switching frequency 1

110kHz

nearly constant

Switching frequency 2

400kHz

nearly constant

Switching frequency 3

65kHz to 280kHz

input voltage and load dependent

-25°C to +70°C (-13°F to 158°F)

reduce output power according Fig. 15-1

Storage temperature

-40 to +85°C (-40°F to 185°F)

for storage and transportation

Output de-rating

2W/°C

60-70°C (140°F to 158°F)

5 to 95% r.H.

IEC 60068-2-30

Vibration sinusoidal

2-17.8Hz: ±1.6mm; 17.8-500Hz: 2g

2 hours / axis

IEC 60068-2-6

Shock

30g 6ms, 20g 11ms

3 bumps / direction, 18 bumps in total

IEC 60068-2-27

Altitude

0 to 2000m (0 to 6 560ft)

without any restrictions

2000 to 6000m (6 560 to 20 000ft)

reduce output power or ambient temperature,

see Fig. 15-2

IEC 62103, EN 50178, overvoltage category II

Altitude de-rating

5W/1000m or 5°C/1000m

> 2000m (6500ft), see Fig. 15-2

Over-voltage category

III

IEC 62103, EN 50178, altitudes up to 2000m

II

altitudes from 2000m to 6000m

Degree of pollution

2

IEC 62103, EN 50178, not conductive

*)

Operational temperature is the same as the ambient temperature and is defined as the air temperature 2cm below the unit.

**) Do not energize while condensation is present
