Overview

Multi-purpose power source available in AC, DC or AC/DC used for energizing a wide variety of circuits and components for troubleshooting and repair. This power supply is a necessity for all in-shop and field service electrical technicians. Testing applications include:

• Check contactors
• Test run small motors
• Operate circuit breakers
• Useful for DC fields voltage drop test
• Power-up substation relays or for unregulated charging of substation batteries
• Suitable for other applications requiring a variable voltage supply.

Both the voltage and current output levels can be simultaneously read and monitored with the highly accurate meters. The separate output terminals for both AC and DC voltage provide convenient hookup configurations depending on the type of component being tested.
