220V Variable DC Power Supply

Industrial Automation & Global Grid Emulation

Technical Overview

The 220V variable DC power supply is the workhorse of industrial automation and international product compliance. In power generation and substation environments, 220V DC is the standard control voltage for switchgear tripping coils and auxiliary backup systems. Utility engineers require robust, high-current 220V supplies to test the actuation force and timing of massive DC circuit breakers. From a global manufacturing perspective, 220V DC simulates the rectified output of the 230V AC mains found in Europe and Asia. This allows test engineers to validate the 'Universal Input' capabilities of power supplies and industrial drives destined for export. These units are built with ruggedized topology to handle high inductive kickback from large DC motors.

Application Engineering Note

Mandatory for heavy industry. A 220V supply allows for the simulation of the 200V-250V DC link found in industrial Variable Frequency Drives (VFDs) and ensures compliance with IEC standards for global equipment export.

Compliance Standards

IEC 60364 (Low Voltage Installations), IEC 60038 (Standard Voltages), EN 50160 (Voltage Characteristics)

Primary Use Cases

Substation Switchgear Coil Testing
Export Market Appliance Validation (230V Rectified)
Industrial DC Motor Drives (200V Class)
Magnetic Levitation & Bearing Research

Frequently Asked Questions (220V)

Can I use this for testing motors designed for 230V AC?

Only if the motor is a 'Universal Motor' (brushed) or if you are testing the DC Link stage of a VFD. You cannot run a standard induction AC motor directly from a DC supply. However, this unit is perfect for simulating the rectified DC bus voltage that powers the VFD inverter.

Does this unit handle inductive kickback from large solenoids?

Yes, our 220V industrial series typically includes output protection diodes and capacitors to absorb reverse EMF generated when testing large inductive loads like switchgear coils or DC motors.
