 SLAC
Series
AC Power/Signal—NEMA-4X
The SLAC Series suppressor was specifically
designed to protect electronic instruments used by the water and
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 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 & 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.
