Product Description

250VA Single Phase Control Transformer 220V/230V/240V To 24V




1. Feature

The transformer that supplies power to the control appliance in the control circuit is called the control transformer. It is commonly used in 380/200V or 380/24V, 220/24V circuits, that is, the power supply is 380V, but the control appliance is 220V (or 24V). Then use a control transformer to reduce 380V to 220V (or 24V). The control transformer is generally single-phase.
