Power-Factor Meters

Drilling Plan

The A&M Model 4951 power factor meters are designed to meet the requirements of MIL-M-19261 and MIL-M-16034. They are supplied as either self-contained or as a “matched set” with external transducer. In the external transducer configuration the transducer is matched to the meter. Both configurations are sealed watertight.
