MOVIDRIVE
®
MDR60A regenerative power supply unit
In MOVIDRIVE
®
drive inverters operating in regenerative mode (4Q operation), the
MOVIDRIVE
®
MDR60A regenerative power supply unit can be used as an alternative
to braking resistors. The prerequisite is a powerful supply system. For more detailed in-
formation, refer to the "MOVIDRIVE
®
MDR60A Regenerative Power Supply Unit"
system manual. This system manual can be ordered from SEW-EURODRIVE.
MOVIDRIVE
®
MDR60A supplies the DC link circuit of the connected MOVIDRIVE
®
drive inverter with electrical power from the supply system in motor operation and
returns regenerative power to the supply system in regenerative operation.
UL approval
UL and cUL approval has been granted for the entire MOVIDRIVE
®
MDR60A0370-
503-00 and MDR60A0750-503-00 range of units. cUL is equivalent to CSA approval.
The MOVIDRIVE
®
MDR60A1320-503-00 unit does not have UL or cUL approval.
