Megger MPU690 Proving Unit
The Megger MPU690 Proving Unit is a portable battery operated unit capable of verifying the correct functionality of a voltage tester.
The Megger MPU690 Proving Unit can generate a range of voltages from 50 to 690 volts in five steps.
Once the Megger MPU690 Proving Unit is turned on it will first generate 690 volts before slowly going down through each voltage step until the device switches off.
Each of these voltage steps are indicated by an LED with a power indicator LED that highlights an exhausted battery.
An automatic power on feature when probes are inserted into the output terminals, generating a 50Hz output which will simulate the AC mains supply.
Output power rating and spacing of the output terminals allows Megger MPU690 Proving Unit to establish the correct operation of voltage indicators.
