Uninterruptible power supply PPS-1220-00 direct current (UPS) with step-down transformer 12V, 2A. Designed for uninterrupted 12V power supply, as well as continuous recharging of rechargeable batteries (AB). The source automatically switches to work from the AB in the event of a 220V network voltage failure, and in the event of a discharge, the AB automatically disconnects it from the load. The PPS source is equipped with circuits for monitoring the mains voltage, output voltage, case opening, thanks to which the following messages are issued: NETWORK FAILURE or OUTPUT FAILURE, ORPUS BREAK. The output of the source is protected by an electronic current limiting module. The charger has electronic protection against short-circuit and violation of the polarity of the battery inclusion, with a stabilizer of the charge current of the battery. The sources are equipped with an AB disconnection unit, network and output control units, and a lock.
