Switching Frequencies

The power supply has three converters included. Two converters have a fixed switching

frequency and one operates with a variable switching frequency.

Switching frequency 1

110kHz

PFC converter

Switching frequency 2

110kHz to 140kHz

Main converter, output power dependent

Switching frequency 3

60kHz

Auxiliary converter

-40°C to +70°C (-40°F to 158°F)

See also Fig. 17-1

Storage temperature

-40°C to +85°C (-40°F to 185°F)

For storage and transportation

Output de-rating

6.4W/°C

12W/°C

+45°C to +60°C (113°F to 140°F), see Fig. 17-1

+60°C to +70°C (140°F to 158°F), see Fig. 17-1

The de-rating is not hardware controlled. The customer has to take care by himself to

stay below the de-rated current limits in order not to overload the unit.

Above 2000m (6500ft), see Fig. 17-2

Over-voltage category

III

IEC 62477-1, altitudes up to 2000m

II

For altitudes from 2000m to 6000m

Degree of pollution

LABS compatibility

The unit does not release any silicone or other LABS-critical substances and is suitable for

use in paint shops.

Corrosive gases

ISA-71.04-1985, Severity Level G3, IEC 60068-2-60 Test Ke Method 4

Audible noise

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

short circuit.

1) Operational temperature is the same as the ambient or surrounding temperature and is defined as the air temperature 2cm below the unit.

2) Do not energize while condensation is present

3) Tested in combination with DIN-Rails according to EN 60715 with a height of 15mm and a thickness of 1.3mm and standard orientation.
