Power supply unit for emergency lamps that may need to be used in areas
with radiation. The power supply consists of a transformer, a diode
bridge, capacitors and an optional voltage stabilisation device. It
converts a 207V to 253V 50Hz AC to a stable DC voltage and current, as
required by the LED load.
