The Haydon 16 way power supply is enclosed in a metal clam shell style case and is ideal for powering CCTV surveillance systems. Each output features PTC resettable fuses which provide overcurrent protection and automatic reset.
The overcurrent protection PTC element is serially connected to the circuit and under normal circumstances it provides a low resistance state and can ensure the normal working of the circuit. If a short circuit or unusually high current occurs, the PTC fuses cut in to reduce the voltage down to a trickle thus preventing damage and protecting the equipment. The fuses will then reset automatically once the fault in the overcurrent is removed. This saves money by eliminating maintenance and replacement costs and also avoids a continuously circulating switching state which can
cause circuit damage.
