18 IGBT Power Converter 200A [Patent No. EP1 126 591 B1] 02.08
3.3 Ambient conditions
Misuse The instrument is not suitable for use in areas with an explosion hazard (Ex
areas).
Mounting site The installation site should be free from vibration, dust and corrosive media.
Climatic
conditions - Relative humidity: 5...85 % no condensation (3K3 as per EN 60721)
- Max. air inlet temperature 35°C
- Ambient temperature range: 5 ... 40 °C (3K3 as per EN 60721)
- Storage temperature range: -10...70 °C
- The cable between the load and the IPC should be as short as possible and
not exceed 50 m.
Power loss Power loss occurs in the form of thermal discharge at the cooling body of the
power converter and has to be discharged at the place of installation (e.g. in
the switch cabinet) in accordance with the climatic conditions.
Example of the

heating
elements
Resistive loads and Molybdenum Disilicid heating elements:
Heating element data: Load voltage = 75V; load current = 130A
h Determine the max. load voltage actually taken (e.g. 75V) and find the point
intersecting with the curve for the voltage supply in the power section. The
Y axis shows the attendant power loss factor of, e.g., 7.5.
IPC type: 709050/83-12-400-90-200/252
Load voltage = 90V
Load current = 200A
Voltage supply to the power section = 400V
