Delta DCO1500UH Orion Industrial Control Transformer
The Delta DCO1500UH is a high-capacity, industrial-grade control transformer from the Orion family. Engineered with premium Copper (CU) windings, this 1500VA unit is designed to provide stable voltage to electromagnetic devices such as solenoids, contactors, and relays within industrial control panels.
By stepping down high primary voltages (480V or 600V) to standard control voltages (120V or 240V), it ensures that sensitive control circuits are isolated and protected from electrical noise and fluctuations on the main power lines.
Key Performance Features
Orion Series Reliability: Designed specifically for high-inrush applications, ensuring that control components receive consistent power during startup.
Copper Windings: Utilizing high-conductivity copper (CU) for superior thermal efficiency and a compact footprint compared to aluminum-wound alternatives.
Dual Primary/Secondary Capability: Offers versatile wiring configurations to accommodate both 480V/600V inputs and 120V/240V outputs.
Rugged Construction: Built to withstand the harsh vibrations and temperatures typical of industrial motor control centers.
Safety Certified: Fully UL Listed and CSA Certified, meeting rigorous North American safety standards for industrial machinery.

Application & Installation
This transformer is an ideal solution for powering industrial logic controllers (PLCs), human-machine interfaces (HMIs), and heavy-duty motor starters. The dual-voltage capability makes it a versatile “stock” item for facilities running both 480V and 600V power systems.
Installation Note: Ensure that the total volt-ampere (VA) load of all connected devices, including initial inrush currents, does not exceed the 1500VA rating to prevent overheating and voltage drop.
