Megger MPU 690 Proving Unit MPU690 (TPT220 Accessory)

Description

The Megger MPU690 is a portable, battery-powered proving unit used to verify the correct functioning of two-pole voltage testers, including the Megger TPT220. It simulates an AC mains supply, providing a reliable and safe voltage source for confirming that a voltage tester is working accurately before use.

Key features

• Five stepped output voltages: The unit generates nominal output voltages of 50V, 100V, 230V, 400V, and 690V.
• Automatic operation: The MPU690 automatically powers on when the probes of a voltage tester are inserted into its terminals and turns off automatically after a test is completed.
• Testing sequence: When activated, the unit first generates 690V and then slowly ramps down through each voltage step, with an LED indicating each level.
• High output power: With a maximum output of 10W, the MPU690 can test both lamp-type voltage indicators and modern electronic units.
• Extended battery life: Despite its high output, the MPU690 is designed for long battery life.
• Magnetic base: A magnetic base is included for convenient, hands-free operation.
• Rugged case: The unit is built with a rugged protective case for durability.
