WSP MODULAR SERIES
About the Product
In order to be compatible with power automation, precision controls, remote controls and electrical system monitoring, a great deal of electronic devices are now being installed indoors.
Surge, which may be caused by lighting, lightning strike, circuit breakdown or on-off operations may easily damage equipment or even threaten personal safety. To prevent surge damage, surge protection devices are installed.
WII Surge Protection Devices (SPD) can be divided into two categories; module combination type providing lightning warning and remote monitoring control devices with alarms; and integrally molded type, which are designed to release intense current.
Our metal oxide varistor (MOV) and the anti-fire enclosure of the module combination type are UL approved and certified. The enclosure of the integrally molded type is made of self-extinguishing resin, which enhances its safety.
Model Number Explanation
WSP – X / Y + Z
X = Type of Protection (B+C or C)
Y = Number of Modules (1 – 4)
Z = Equipotential Isolation Protection Device: NPE and/or Modular Monitor (FS or AS)
FS Signal Monitor Device
If damage occurs to a remote surge protection device and is not detected, an FS signal monitor device will transmit to a central control room, altering an operation of possible problems.
Function:
CIC’s FS device can be combined with B+C or C type surge protections devices to alert technicians that a surge protection device may need to be replaced by way of mechanical linkage to a central control room via NC (normal close) or NO (normal open) action.
AS Sound Monitor Device
Our AS sound monitor device can be combined with B+C or C type surge protection devices as a finished product suitable for locations not easily visible. In case a surge protection device is damaged, the AS will emit a high frequency sound complimented by an LED light to attract attention.
Function
The alarm may sound for up to 24 hours. Once the module has been replaced, a green LED will signal that the surge protection device has been returned to normal function.
