Control transformers are available from 63 to 3200VA

The low inrush current design of control transformers from Southern Electronics exhibitor, Block, can be protected using, for example, inexpensive and readily available motor protection circuit breakers.

Block preview edit_tmb The reduced inrush current also minimises the risk of disturbance to the associated circuits when the supply is turned on. The transformers are available from 63 to 3200VA. The double-wound single-phase control transformers are available in five types: the ST, STE, STEU, STU and USTE.

The ST is the basic 230, 400 or 690V version, the STE has a DIN rail/ four-hole fixing plate, the STEU is available as 230 and 400V, the STU and USTE have multiple inputs for worldwide use

Secondary voltages available include 12, 24, 48 115 and 230V, according to the transformers model and rating. Most types are UL and VDE approved; special requirements can be manufactured on request.
