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 I=4,5A+
0,5A battery charging*. 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.
