Environment

Operating temperature

-25°C to +70°C

The operational temperature is the ambient or surrounding temperature and is defined as the air temperature 2 cm below the device.

Storage temperature

-40°C to +85°C

For storage and transport

Output derating

3.2 W/°C
6 W/°C
15 W/1000 m or 5 K/1000 m
9 W/ -5 kPa or 3 K/-5 kPa

Between +45°C and +60°C
Between +60°C and +70°C
For altitudes > 2000 m see Fig. below
For atmospheric pressures < 80 kPa, see Fig. below

The derating is not hardware controlled. The customer must take care by himself to stay below the de-rated current limits in order not to overload the unit.

Humidity

5 to 95% r.h.

According to IEC 60068-2-30

Atmospheric pressure

110 – 47 kPa

See Fig. below for details

Altitude

Up to 5000 m

See Fig. below for details

Degree of pollution

According to IEC 62477‑1, not conductive

Vibration sinusoidal

2 - 17.8 Hz: ±1.6 mm; 17.8 – 500 Hz: 2 g
2 hours/axis

According to IEC 60068‑2‑6

Shock

30 g 6 ms, 20 g 11 ms
3 bumps/direction, 18 bumps in total

According to IEC 60068‑2‑27

Shock and vibration is tested in combination with DIN‑Rails according to EN 60715 with a height of 15 mm and a thickness of 1.3 mm and standard orientation.

Audible noise

Some audible noise may be emitted from the power supply during no load, overload or short circuit.
