The EMV 1200 is a signal powered 3 digit LCD voltmeter with 12.5mm (0.5") digit height. It features a 4 to 25VDC range. The meter can be panel mounted by drilling a 5.5mm (0.22") hole. Connection to the meter is via two wires.
Note: At voltages below 4.0VDC, the LCD will display LO and will ultimately go blank. At voltages in excess of 25.0VDC, the LCD will display HI. Do NOT exceed 50VDC, as this may damage the meter. The module includes reverse polarity protection up to 30V for up to 30 seconds.
