HW SERIES SURGE PROTECTORS
Custom Surge protection is our specialty. Custom versions are available including mixed or
special voltages, different connectors or wiring options. Contact us for details.
OPERATION:
The Zap-Tech protector will repetitively protect and reset without
degradation up to it's maximum repetitive self-reset surge. If it is
subjected to more than it's maximum repetitive self-reset surge, the
device will remain in a clamped mode indicating that it should be
removedor replaced while keeping the equipment safe from
subsequent surges.
INSTALLATION:
Zap-Tech protectors should be installed in series with the incoming
communication line at the port of the equipment being protected. The
protector's grounding wire must be connected to the chassis ground
of the protected equipment.
IMPORTANT!
It is important that the protector and the chassis of the equipment to be
protected are both properly grounded to a properly earthed electrical
safety ground via the equipment's 3-prong power cord and/or a ground
wire of 14 AWG or larger. Protectors should be installed at both ends of
communication lines to ensure equipment protection at each end.
All specifications are subject to change without notice.
Detailed specifications for specific versions available on request.
