Features

The DPM 912 is a large 3½ Digit LCD Voltmeter. The signal being measured is also used to power the meter, including the backlight. The meter features a 3 to 60V measurement range, with a resolution of 10mV between 3.00 and 19.99V and 100mV between 20.0 and 60.0V. When the voltage drops below 3V, LO is displayed (down to 2.8V, when the display will turn off). ‘HI’ is displayed when the voltage goes above 60V.

Screw terminals allow for quick and easy connection. The meter is housed in a robust carrier which can be bolted in place or panel mounted using the low profi le bezel and clips provided. An IP67 / NEMA 4X bezel is also available for protection against dust and moisture.

This is a popular part, normally stocked in high quantity and suitable for new designs.
