1. Technical description.

1.1. General description.

Buffer-type power supply units are intended for continuous power supply to devices that require stabilised voltage

of 12V DC (+/-15%). The power supply provides a voltage of U=13,8V DC with an output current of:

1. Output current of 10A + 1A battery charging*

2. Output current of 7A + 4A battery charging*

Total device current + battery: 11A max.

In case of power voltage decay, prompt switching to battery supply occurs. The power supply unit is protected

against a short circuit, an overload, a surge or over voltage protection.

The circuit of the shock protection shall be performed with a particular care, i.e. the yellow and green protection wire of the power cable shall be connected from one side to the terminal marked by the symbol of in the casing of the power-supply. Operation of the power-supply without the properly made and fully operational circuit of the shock protection is UNACCEPTABLE! It can result in failure of devices and electric shock. 4.

3. Cooperation with the MPSB12 automation module (option). The MPSB12 automation module is intended for indicating the operating status of buffer power supplies, PSB 13,8V type. The PCB board features LEDs that indicate PSU operating status (presence of AC voltage, presence of DC voltage, battery voltage). The module is also equipped with technical outputs of: EPS - AC power loss, PSU - PSU failure, LoB - low battery voltage. Element no.
