Description :

This is Control Transformer.

TEMCo Industrial Control Transformers are used to convert all standard international voltages. Many models are dual frequency rated for 50 and 60 Hz. TEMCo’s transformers are built to last, guaranteed! That’s why we back these with a decade long warranty.
Our industrial control transformers change supply voltages for the operation of components such as contactors, solenoids, relays, and timers. They accommodate momentary current inrush produced when electromagnetic components are energized without compromising secondary voltage stability. Maximum Safety is assured through the secondary control circuit which is isolated from the primary line circuit.

Voltage regulation of TEMCo Industrial Control Transformers exceeds standards recommended by the National Electrical Manufacturers Association. Secondary circuit voltage drop between no-load and momentary overload remains exceptionally low, maintaining excellent voltage regulation.
TEMCo has the capability to wind any custom control transformer with no penalty for small quantities. Please call us with your requirements for a Fast Turnaround Quote.

 

Features :

1. Silicon Steel Lamination – Minimize core losses and increase efficiency.

2. Excellent Regulation – Designs incorporate precision wound coils layers and
exceed NEMA requirements.

3. High Efficiency and Heat Dissipation – Every coil is precision bobbin-wound .

4. Versatile Mounting – Vertically or horizontally.
