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