CCTV – POWER SUPPLY
The input is 220 volts AC fused at 2 amps and the system provides a regulated 15V DC to the distribution board.
2. ADJUSTABLE VOLTAGE OUTPUT
The diodes can be linked to raise each terminal output from 13.2V DC to 15V DC for line loss compensation.
3. BATTERY BACK-UP
External Battery can be used which is charged at 14.4 volts from the Power Supply and switched and fused on the Battery isolation board.
4. TERMINAL OUTPUT FUSING
Each of the 10 outputs has a resettable fuse at 1.5 amps on the negative side.
5. MAINS FAILURE
A relay disconnects the Power Supply and connects the Battery directly to the output terminals. In the event of a prolonged failure the Battery will be disconnected by another relay from the output and the low Battery L.E.D. will light up.
6. REGULATION AND PROTECTION
The unit is protected against short circuits and over voltage.
The Ammeter monitors the TOTAL system being the combination of camera drain and charging current.
The Voltmeter monitors the TOTAL system voltage and in the event of mains failure, the Battery voltage.
