Uninterruptible power supply unit ABP-OOPT-8-230-50-220N-UHL4

Operating mode without bypass (BYPASS switch in position 0): the control system monitors battery voltage, input mains voltage, load current and turns off power to the load when the batteries are overloaded or discharged.

Bypass operating mode (BYPASS switch in position 1): when the switch (UPS) on the front panel is turned off, there is an overload, deviations of the battery parameters beyond acceptable limits and any UPS accident, the load power is switched to the main (if available) source via the circuit - the network connector, BYPASS switch, normally closed contacts of relay K2, load connector.

The UPS is turned on and off by a switch (SU Power), which completely disconnects the CS elements from the battery input; there is also a button (power) on the front panel that turns off the UPS by switching it to standby mode. In case of prolonged overload (the OVERLOAD indicator lights up), deep discharge or overvoltage of the batteries, the inverter is turned off, the UPS goes into a protected state, signaling a malfunction. After eliminating the cause of the problem, you must turn off and turn on the switch (UPS) using the (power) button or switch (SU Power) on the front panel.
