Pelco WCS4-20B Outdoor 4-Output 24VAC 12A Multiple Camera Power Supply with Circuit Breaker (Class 2)

Power supplies in the WCS Series offer a variety of configurations for powering up to four outdoor units from a single power source. The power supplies provide 24 VAC output for 1-4 units, depending on the model selected. To compensate for voltage losses over long wire runs, 28 VAC outputs are available on all models. The input voltage of all models is also selectable. For integrated systems such as Spectra and Esprit, the power supplies are capable of handling pan/tilt, heater and blower operation in addition to the camera.

The WCS4-20B has four protected outputs with self-resetting circuit breakers and is capable of handling up to 12 A (288 VA) of total load. Fuses provide a greater degree of protection for the unit because they are faster acting and more precise. Circuit breakers will self-reset when the fault is corrected, eliminating the need for replacing fuses. However, the amount of current required to trip a circuit breaker can vary as much as 100 percent, depending on temperature. In the fused models, the values of fuses can be changed depending upon the specific current requirements of the equipment connected.
