Switching Frequencies
PFC converter 80...130 kHz Input voltage and load dependent
Main converter 75...180 kHz Output voltage and load dependent
Auxiliary converter 60 kHz Fixed frequency
Attributes Values Notes
Operational temperature -25…+70 °C (-13…+158 °F)
Operational temperature is the same as the ambient or surrounding
temperature and is defined as the air temperature 2 cm (0.79 in.)
below the unit.
Storage temperature -40…+85 °C (-40…+185 °F) For storage and transportation
Output derating
12 W/°C (12 W/1.8 °F),
30 W/1000 m (30 W/3281 ft),
or 5 °C/1000 m (9 °F/3281 ft)
Between 55…70 °C (131…140 °F)
For altitudes >2000 m (6560 ft), see
Figure 19
The derating is not hardware-controlled. You have to take this into consideration to stay below the
derated current limits in order not to overload the unit.
Humidity 5...95% r.h. According to IEC 60068-2-30
Atmospheric pressure 110…54 kPa See Figure 19 for details
Altitude Up to 5000 m (16,400 ft) See Figure 19 for details
Overvoltage category II According to IEC 60664-1, for altitudes up to 5000 m (16,400 ft)
Impulse withstand voltages
4 kV (according to overvoltage
category III) Input to PE According to IEC 60664-1, for altitudes up to 2000 m
(6560 ft)
Degree of pollution 2 According to IEC 60664-1, not conductive
Vibration sinusoidal
2…17.8 Hz: ±1.6 mm (0.06 in.);
17.8…500 Hz: 2 g (19.61 m/s
2
)
2 hours / axis
According to IEC 60068-2-6
Shock
30 g 6 ms, 20 g 11 ms
3 bumps per direction,
18 bumps in total
According to IEC 60068-2-27
Shock and vibration are tested in combination with DIN rails according to EN 60715 with a height of 15
mm (0.59 in.) and a thickness of 1.3 mm (0.05 in.) and standard orientation.
LABS compatibility
As a rule, only non-silicon precipitating materials are used. The unit conforms to the LABS criteria and is
suitable for use in paint shops.
Corrosive gases
Tested according to ISA-71.04-1985, Severity Level G3 and IEC 60068-2-60 Test Ke Method 4 for a
service life of 10 years min in these environments.
Audible noise Some audible noise may be emitted from the power supply during no load, overload, or short circuit.
