Edco

™

SLAC Series

AC Power/Signal

The Edco

™

SLAC Series suppressor is specifically designed to protect electronic

instruments used by the water/wastewater industries. It combines hybrid AC

power protection and signal line protection in a NEMA-4X polycarbonate case.

The AC power suppressor can supply up to 1875 Watts and has a 15 Amp

replaceable fuse to prevent overloading of the protective elements. A “Power

ON” LED provides visual indication that power is applied to instruments. Signal

line protection is accomplished by the Edco

™

PC642 Series available in a variety

of voltage clamps. Signal current can be monitored by reading the voltage

across the 10 V, 1% resistors (TP1 & TP2 or TP3 & TP4). All leads going to the

Edco

™

SLAC board are terminated by quick disconnect or barrier block

connectors to facilitate easy removal for service or replacement.
