[20-Way] 12V DC 20Amp (240W) CCTV Metal Box Professional PSU (20x1A PTC Outputs)

12v DC Professional CCTV Power Supply with PTC Technology
20x 1.0A PTC (resettable) Fused Outputs
Total 20Amp

The VRS1220000-20-S PSU is a high power switch mode power supplies ideal for use in professional CCTV applications. Featuring a regulated 12V dc power module, continuously supplying full rated current to load via multi-way fused outputs. The highly efficient switch mode design generates less heat and ensures low operating costs. The 1.5mm powder coated steel enclosure has been specifically designed with multiple rear cable entry points, ideal for multi camera systems. The fused output modules allow multiple circuits to be individually protected while providing fuse health status via onboard LED’s.

When traditional fuses are being used for overcurrent protection it can only protect once then it must be replaced. The PTC resetable fuse is a new-type of overcurrent protection element which has two functions providing 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 PTC fuse will automatically reset once the fault in the overcurrent is removed. The PTC elements will automatically return to its low resistance state, which not only avoids maintenance or replacement but also avoids a continuously circulating switching state which can cause circuit damage
