An analog panel voltmeter with a moving-coil movement and magnetic damping, reading AC voltage from 15 V up to 1500 V in standard ranges. Rated voltages include 15 V, 30 V, 50 V, 75 V, 100 V, 150 V, 250 V, 300 V, 450 V, 500 V, 750 V, 1000 V and 1500 V, with class 1.5 accuracy and 50/60 Hz frequency. The 80 x 80 mm front panel and 76 x 76 mm cutout suit flush mounting in distribution boards, motor control centres, generator panels and test benches. Above 600 V the circuit needs a matching voltage transformer, so confirm the ratio and connection method first.Key details:Materials: Flame-retardant ABS engineering plastic case; scratch-resistant transparent dial coverDimensions: 80 x 80 mm front panel; 76 x 76 mm panel cutout
