Control Transformer A 1000 VA 600/480 V to 120/240 V Open Core and Coil Delta Transformers DCO1000UH

What this product is for

This open core and coil control transformer provides isolated 120/240 V control power from a 600/480 V supply for industrial panels, machine automation, motor control circuits, HVAC controls, lighting circuits and general circuit isolation.

Use for

Use for control cabinets, OEM equipment, relay and contactor circuits, pilot devices, light-duty machine control and other applications where a 1-phase 1000 VA control transformer is required.

Avoid for

Avoid for applications with unusually high inrush or machine tool duty unless the load profile has been checked against transformer sizing requirements. Do not use where an enclosed transformer is required for the installation environment.

Best for

Best for electricians, panel builders and maintenance teams needing a compact open-style transformer with copper windings, CSA certification and common 600/480 V to 120/240 V control voltage conversion.

Installed in

Typically installed in industrial control panels, factory automation systems, machinery, HVAC equipment rooms and electrical enclosures. Approximate overall size is 4.92 in W x 4.69 in D x 4.37 in H (125 x 119 x 111 mm), which helps when panel space is limited.

Why this product exists

It exists to step down common Canadian industrial supply voltages to isolated control voltages for coils, relays, pilot lights and similar loads. Open-style control transformers are commonly selected when the transformer will be mounted inside another enclosure rather than supplied in its own housing.

Typical buying guidance: 1000 VA equals about 8.33 A at 120 V or 4.17 A at 240 V on the secondary. Actual usable capacity depends on connected load, inrush current, duty cycle and protection method.

Compared with similar products

Compared with enclosed control transformers, this open core and coil model is intended for mounting inside a panel or machine enclosure. Compared with smaller VA sizes, the 1000 VA rating supports larger control loads, but load type still matters because high inrush devices can require additional sizing margin.
