Note:
(1) Application with one UR11 rectifier unit feeding a CFW-11M with the same power rating.
(2) Add more UR11 for bigger motor power ratings, according to
(3) Nominal current in permanent regimen at the following conditions:
- Temperature around the rectifier: -10 °C to 45 °C (14 °F to 113 °F). The rectifier is able to operate in environments with temperatures up to 55 °C (131 °F), if
a reduction of 2 % in the output current is applied for each Celsius degree (or 1.11 % each °F) above 45 °C (113 °F).
- Relative humidity: 5 % to 90 % without condensation.
- Altitude: 1000 m (3.300 ft). Above 1000 m up to 4000 m (3.300 ft to 13.200 ft) the output current must be reduced in 1 % for each 100 m (or 0.6 %
each 100 ft) above 1000 m (3.300 ft).
- Environment with pollution degree 2 (according to EN50178 and UL508C).
(4) The motor ratings are merely a guide for 440 V (400 V line), 575 V (500 V line) and 690 V (600 V line), IV pole WEG motors. The adequate rectifier
sizing shall be based on the rated current of the motor used.
(5) The information provided about the rectifier losses is valid for the rated operating condition, i.e., for rated output current.
