Edco SLAC Series
AC Power/Signal
Power Switching & Controls
For Business-Critical Continuity
TM
The Edco SLAC Series suppressor was 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 ohm, 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.
