AC and Data Surge Protector for
the Water Industry
SLAC Series



The SLAC Series surge suppressor was specifically designed to protect electronic instruments used by the water industry. It combines hybrid AC power protection and signal line protection in a NEMA 4X polycarbonate case.

The AC power surge suppressor can supply up to 600 watts (total) on two separate output connectors and has a 10 amp replaceable fuse to prevent overloading of the protective elements. An "INST PWR" LED provides visual indication that power is applied to instruments. Signal line surge protection is accomplished by the PC641 or PC642 Series in a variety of voltage clamps. Signal current can be monitored by reading the voltage across the l00hm, 1% resistors (TP1 & TP @ or TP3 & TP4). All leads going to the SLAC board are terminated by quick disconnect or barrier block connectors to facilitate easy removal for service or replacement.
