SPMC1402 Unidrive SPMC/U

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. See section Unidrive SPMC/U external 24V
supply requirements and section Unidrive SPM power supply on page 4. 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.
The 24V supply must be protected using a 4A slow-blow fuse, one for each supply pole.
Control connections to the Unidrive SPMC/U should be made with 0.5mm2 cable.
The status relay contacts are rated for switching non-inductive loads at 250Vac 6A non-inductive, up to 4Adc if the voltage is limited to 40V or up to
400mA dc if the voltage is limited to 250Vdc. Protection from overcurrent must be provided.

Drives from the Unidrive and Commander families can be connected on a common DC bus system, in order

to circulate energy between drives with opposing energy flow, supplied from a controlled rectifier input (SPMC), an active input (SPMA or SPMD) or an existing DC source.
