Haier AC UPS Device for Haier DC Inverters 1 Ton and 1.5 Ton

The PCB detects the input power including the Mains power supply, the input terminal connects with the UPS and the output terminal connects with the UPS port of the computer board within the air conditioning chamber; the signas detected are sent to the MCU of the computer board for intelligently distinguishing the Mains power supply from the UPS supply the Mains is detected and identified as AC220V the detection board will output the mains signal to enable the air conditioner to run under the Mains operation mode if the Main detected and identified as 0V the UPS signal will be output to automatically switch to the UPS supply mode, and active the low-frequency operation of the air conditioner.

Comfort: The power supply control mechanisms for Mains power supply and the emergency control mechanism for the storage battery power supply are in the converter air conditioner: when the Mains fails, the controller will call the emergency mechanism of UPS, storage battery and dual-circuit power supply. to ensure normal operation.

Reliability: the G-TYPE torque control enables the compressor to run at low frequency, and at an amplitude 20% lower than the competitors, to improve the reliability of operation without any impairment to the service life
