Martindale Part No: MARPD690
The Martindale PD690 is a 700V AC proving device, designed to enable voltage indicators to be fully checked, in compliance with Health & Safety recommendations. Using a voltage indicator without first proving it is working correctly could prove fatal.
The PPD690 is compatible with all Martindale Voltage Indicators including the New VI-15000 and VI13800. This model is suitable for proving any two pole voltage tester, with LED or LCD indication and will illuminate all LEDs up to 690V.
The PD690 can also check Drummond and other filament test lamps as its output is sufficient to illuminate the bulb.
There is now a facility to power the PD690 proving devices with the addition of a 12V DC power connection point. The units can be powered by either alkaline batteries or a 12V power supply. There are two power supply units available for the proving devices, the PSUPD230 and the PSUHPAT12. The PSUPD230 can be connected to mains power and the PSUHPAT12 is a 12v power supply suitable for use in a car/van cigarette lighter.
