Voltage Indicator Proving Units

MARTINDALE PD430 and PD440 Proving Unit Using a voltage indicator without first proving it is working correctly has proved fatal. The Martindale PD430 proving unit features a low 50V check as well as a high 440Vac, the PD440 is a 440Vac proving unit, designed to enable voltage indicators to be fully checked, in compliance with Health & Safety recommendations Operating Temperature: -10°C to +40°C at max 70% RH Battery: 6 x LR6 / MN1500 1.5V alkaline batteries or equivalent Dimensions: 143 x 84 x 50mm Weight: 400g approx including battery Note Compatible with the Martindale VI13700G & the new Martindale VI13700/2. Martindale Proving Units The Martindale proving unit has an output voltage rating of 440VAC. The units can be powered by either alkaline batteries or a 12V power supply. There are two power supply units for the proving devices such as PSUPD230 and 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. It is compatible with the VI13700G and the new VI13800.
