703 Series
The 703 Remote Power Controllers are designed to sense the current level flowing through their contacts, and to open the circuit
when the current exceeds the specified current rating. These units use our unique magnetic latching motor design to minimize
power consumption. These units are fully temperature compensated for accurate operation over the full temperature range.
The 703 circuitry has 1500 watts of Peak Power Dissipation transient suppression built in so it can withstand the rigors of even the
noisiest of supply voltages. Utilizing all space age approved materials, the 703 Remote Power Controllers are ideal for
demanding applications.
