CONTROL TRANSFORMERS

Through their additional ±5 % tappings, control transformers equalise mains undervoltages and overvoltages and are able to suppress short circuit in case of malfunction to permit auxiliary circuits to function unearthed. A control transformer has two separate coils. Version sizes range from single-phased up to 25 kVA and multi-phased up to 40 kVA. Coil types are available in solder plug, clamp and bracket versions.
