The MTL SSP series is a self-healing surge protector that adds AC fault withstand capability and current limiting protection to traditional
hybrid surge technology. The single loop design eliminates the most common cause of surge protector failure (continuous overvoltage/over current
conditions) while adding current limiting protection to the circuit.
The use of Surge Protection Devices on communication lines has increased significantly over the last number of years. However, if the communication
lines are subjected to induced AC power or AC powercross, the surge protector can pose possible safety hazards. In these circumstances, the surge
protector will respond and draw AC current. The magnitude of current could be large enough to represent a fire risk to the surge protector itself
or the thin-gauge UTP (unshielded twisted pair) wiring.
The MTL SSP series incorporates circuitry to mitigate the hazards of induced AC or AC power-cross up to 240Vrms. The SSP stops the flow of current
in milli-seconds to prevent surge protector and wiring damage. Once the AC power is removed, the SSP will cool down and automatically begins normal
operation again.
Should the signal loop be subjected to surges which will not operate the Gas Discharge Tube (GDT), yet operate the other surge protection elements,
the additional network will immediately protect these elements by elevating to high resistance. This will stop current flowing through the device
and damaging the surge protection elements, while protecting the loop equipment from being subjected to these sustained over voltages.
The MTL SSP series also provides overcurrent protection to the wiring and the load. Should a sustained current of 500mA, or greater, be present, the
SSP will stop the current flow, thus providing additional protection to the load and the wiring.
