Note:
(1) Steady state rated current in the following conditions:
- Indicated switching frequency. It is not possible to use the CFW11W G2 inverter with switching frequency of 2.5 kHz, 5 kHz and 10 kHz.
- Ambient temperature around the inverter as specified in
to 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
- 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).
8
- For operation of the inverter in steady state with output frequencies between 0 and 10 Hz, derate the rated output current by 35 %.
(2) One overload every 10 minutes.
overload curves of the IGBTs for Normal Duty (ND) and Heavy Duty (HD) are presented in
conditions, such as ambient temperature around the inverter and output frequency, the maximum operating time of the inverter with overload may be shorter.
