3.5 Unidrive SPMC half controlled thyristor rectifier
For the 200V modules where an external charging circuit is required the
SPMU1401, SPMU1402 and SPMU2402 can be used as detailed
following:
Figure 3-4 Rectifier (SPMC and SPMU)
The Unidrive SPMC is a controlled thyristor rectifier and the SPMU is an uncontrolled rectifier.

The Unidrive SPMC is a half controlled thyristor bridge is used as a front end to the SPMD inverter module or as a stand alone rectifier for several
smaller drives. Soft-start is built in.
The Unidrive SPMU is used as a front end to the SPMD inverter module or as a stand alone rectifier for several smaller drives.
Softstart must be
supplied externally using a resistor and contactor or SPMC
.
An external 24V, 3A power supply is required in addition to the AC supply to allow the rectifier to operate. Control wiring is required between the
rectifier and motoring drive(s) so that if the rectifier indicates a fault the motoring drive(s) will be disabled.
