Emerson Network Power > ASIA > Products > By Type > Surge Protection > Signal > Edco SLAC Series Combined AC Power and Data-Signal Surge Protection

The Edco SLAC surge protective device 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 1,875 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. 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.
