Digital Instruments for AC/DC Systems

These highly versatile digital instruments enable continuous and comprehensive monitoring of fixed site or mobile AC and DC electrical systems. They provide quick easy-to-read and accurate information on all important aspects of electrical system status: voltage, current, power consumed, power available and AC frequency. In addition, abnormal system conditions such as high/low voltage trigger user-adjustable alarms.

All read-outs and programming are controlled via touch pads on the instrument face. LCD displays are easily read, even in bright sunlight. Backlighting is provided for use at night or in low-light installations. Instruments mount in 2 1/8″ diameter hole and standard instrument faces are available 2 1/2″ square.


Displays volts, amps, frequency and wattage of 115/230 VAC systems. High/low volt/frequency alarms. Current transformer included. 2 1/2” square face

ACE meter, same as above with 4-1/4” x 4-1/4” square face

Displays DC volts, amps, energy used/remaining in battery system; 500 amp shunt included. High/low voltage, low amp-hour alarms. 2 1/2”

DCE Meter, same as above with 4-1/4” x 4-1/4” square face

Displays DC volts for three battery banks. High/low voltage alarms. 2 1/2” square face
