Note:
(1) For the CFW11M G2 RB converter, steady-state rated current in the following conditions:
- Indicated switching frequency. It is not possible to use the CFW-11M G2 RB converter with switching frequency of 2.0 kHz, 5 kHz and 10 kHz.
- Ambient temperature around the converter as specified in
55 º C, the output current must be derated by 2 % for each ºC above the maximum temperature specified.
- Air relative humidity: 5 % to 95 % non-condensing.
- Altitude: 1000 m. Above 1000 m up to 4000 m, the output current must be derated by 1 % for each 100 m above 1000 m.
- Environment with pollution degree 2 (as per EN50178 and UL508C).
(2) For the CFW11W G2 RB converter, steady-state rated current in the following conditions:
- Indicated switching frequency. It is not possible to use the CFW-11W G2 RB converter with switching frequency of 2.0 kHz, 5 kHz and 10 kHz.
- Ambient temperature around the converter as specified in
55 º C, the output current must be derated by 0.5 % for each º C above the maximum temperature specified.
- Coolant input temperature as specified in
output current must be derated by 1 % for each º C above the maximum temperature specified.
- Coolant flow as specified in Chapter 3 INSTALLATION AND CONNECTION on page
- Air relative humidity: 5 % to 95 % non-condensing.
- Altitude: 1000 m. Above 1000 m up to 4000 m, the output current must be derated by 1 % for each 100 m above 1000 m.
- Environment with pollution degree 2 (as per EN50178 and UL508C).
(3) One overload every 10 minutes. Table 8.1 on page 8-2
and 3 s). The complete overload curves of the IGBTs for Normal Duty (ND) and Heavy Duty (HD) are presented in
the converter operating conditions, such as air temperature around the converter or coolant temperature, the maximum time for operation of the converter
under overload may reduce.
