Inverter Power Supply SM32

The SM32 devices are AC/DC three-phase half-controlled suppliers designed to supply constant voltage to the DC link inverters.

SM32 is suitable to power supply both single and multiple inverter systems parallel connected to a common DC link.

The precharge of the leveling capacitors, which can be set via internal dip-switches, is performed by partializing the Mains voltage via an input thyristor bridge.

A diagnostic circuit allows to set the delay time for the switching off of the power thyristor during a power dip.
