EMV 1200-40 is an easy to mount LCD digital panel voltmeter with a 4 to 40V measurement range and 200mV resolution.
The EMV 1200-40 is a compact LCD digital panel meter designed for easy single‑hole installation. It measures voltages from 4 V to 40 V DC with 200 mV resolution and indicates "LO" and "HI" when the input is outside the range. The unit includes reverse‑polarity protection, splash‑proof sealing, and a 12.5 mm (0.5") digit height display.
Installation requires drilling a 5.5 mm hole, inserting the threaded stud, washer and nut, and sealing the rear with the provided rubber gasket. The meter is powered from the measured signal and complies with the Low Voltage Directive (LVD 93/68/EEC) and BS EN 61010 safety standards.
