DESCRIPTION

Buffer-type power supply units are intended for continuous power supply to devices that require stabilised
voltage of 24V DC (+/-15%). The power supply provides a voltage of U=27,6V DC with an output current of I=1,5A+ 0,3A
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.
