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 24 V DC (+/-15%). The power supply provides a voltage of U=27,6 V DC with an output current of:
In case of power voltage decay, prompt switching to battery supply occurs. The power supply has the following
protections: short-circuit (SCP), overload (OLP) and overvoltage (OVP).
