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:
In case of power voltage decay, prompt switching to battery supply occurs. The power supply is equipped with
short circuit protection, overload protection, overvoltage and thermal overload protection. The power supply is fitted with a
fan for forced cooling, switching on depending on the temperature and the load of the power supply.
