The PPM Instruments EL-3000-300-60 Fuel Cell Test Electronic Power Load is an air-cooled DC electronic load used to test DC power sources, such as batteries, power supplies, generators, chargers, fuel cells and other power sources. Control is either by a front panel potentiometer or a 0 to +10 V analog control signal on standard units, with computer control options available. Rear connections provide for line power, the analog control signal, current load monitor connections and optional computer interface and load input power block.
