Control Transformers
Control transformers are built to serve electronic circuits that need constant voltage and current at low power and volt amp rating. Control transformers are best suited for industrial environments where electromagnetic devices like solenoids and relays are being deployed. These transformers can regulate output voltage and inrush capability in electromagnetic devices. Current transformers have very high quality insulation across all its winding. A control transformer, typically employed in electronic circuits demanding consistent voltage at a low power or volt-amp rating, serves as an isolation transformer. Control Transformers are specifically designed to convert high-voltage power supply to a lower voltage level suitable for control circuits.
