Power Adapter 230V AC

This power adapter enables sustaining power on power supply decay. It features a built in accumulator and microprocessor controlling. The power adapter can operate in buffer and in cyclic mode. Buffer mode: simultaneous charging the battery and powering a weighing instrument. Cycle mode: operation without plugging to mains 230V, powering a weighing instrument from built in accumulator.The status of the power adapter is indicated by two LED diodes:Green LED diode pulsating. Cycleoperationmode,accumulatorcharged,andsustained with low power supply.Green LED diode shining constantly. Accumulator charging or its sustaining in buffer operation mode.Red LED diode pulsating. Power consumption from the accumulator while being unplugged from 230 V AC mains.Red LED diode shining constantly and periodically sound is heard. Power consumption from accumulator while being unplugged from 230V AC mains, accumulator discharged, charging required (connect the power adapter to mains 230 V AC).Red and green. LED diodes shining constantly and periodically sound is heard (during charging).Fuse of the accumulator defected.No diode is flashing. Power adapter not plugged to 230 V AC mains and there is no power consumption from accumulator.
