Technical Specifications
CFW11W | 5-4
Note:
(1)
Steady state rated current in the following conditions:
Ambient temperature: -0 °C to 40 °C (32 °F to 104 °F) - nominal conditions (measured around the
inverter). 40 °C to 45 °C (104 °F to 113°F) - current derating of 2 % for each 1°C (1.8 °F) above 40 °C
(104 °F).
Coolant input temperature: 0 ºC to 40 ºC (32 °F to 104 °F) according to the coolant used. 40 ºC to 45
ºC (104 °F to 113°F) - current derating of 3 % for each 1°C (1.8 °F) above 40 ºC (104 ºF).
Fluid flow: 20 l/min.
Air relative humidity: 5 % to 90 % non- condensing.
Maximum altitude: up to 1000 m (3,300 ft) - nominal conditions. 1000 m to 4000 m (3,300 ft to 13,200
ft) - current derating of 1 % for each 100 m (or 0.3 % each 100 ft) above 1000 m (3,300 ft) of altitude.
2000 m to 4000 m (6,600 ft to 13,200 ft) – maximum voltage derating of 1.1 % for each 100 m (or 0.33
% each 100 ft) above 2000 m (6,600 ft) , maximum altitude up to 4000 m (13,200 ft).
Pollution degree: 2 (according to EN50178 and UL508C), with non-conductive pollution. The
condensation must not cause conduction through the accumulated residues.

Table 5.1presents only two points of the overload curve (activation time of 1min and 3 s). The complete
IGBT overload curves for Normal and Heavy Duty Cycles are presented next.
