The AC UPS power systems subset described in ES 202 336-1 [1] and TR 102 121 [i.6] provides electrical power
without interruption in the event that commercial power drops to un unacceptable voltage level.
The AC UPS power system provide uninterruptible 230V/400V; 50 Hz voltage according EN 300 132-3 [2], in period
defined by capacity of installed back-up battery.
The AC UPS power systems addressed by the present document can be single phase input/single phase output, three
phases input/single phase output and three phases input/three phases output.
The following configurations of static AC UPS power system will be under the scope of the present document: On-line
AC UPS, Modular On-line AC UPS, Off-line AC UPS and Line-interactive AC UPS, which are depicted in figures 1 to
figure 4.
In the case of paralleled AC UPS systems there can be an aditional control unit (device) which controls parallel
operation of the AC UPS systems. Parallel operation of UPS systems is outside the scope of the present document.
Mandatory and non-mandatory monitoring/supervision information and functions for On-line AC UPS and Modular
On-line AC UPS are given in annex A.
Mandatory and non-mandatory monitoring/supervision information and functions for Off-line AC UPS are given in

NOTE 1: Rectifier and inverter in operation. Inverter synchronized to mains supply but not carrying load current.
NOTE 2: Bold lines indicate the load current path.

Figure 4: Line-interactive AC UPS - normal operation
The main elements of AC UPS power systems are:
- rectifier that converts AC voltage to DC voltage (i.e. 230 VAC/400VAC to DC voltage),
- battery (one or more strings of cells) that stores energy and can power the loads when AC interrupts or
rectifiers fail. There can be test and permanent battery monitoring systems to reduce the failure detection time
and the MTTR,
- protection and distribution (DC bus, breaker, etc.) to power different user loads and discriminate faults,
- inverter that converts DC voltage to AC voltage (i.e. DC voltage to 230 VAC/400VAC),
- Static Bypass Switch (SBS) monitors output and input voltage (mains AC voltage) of UPS, and synchronizes
UPS output voltage to the input voltage, or transfers theinput voltage to the output to supply Current using
equipment,
- External (Manual) Bypass that transfers input voltage to the output to supply Current using equipment, in the
case of UPS failure, UPS service, maintenance, etc.,
- a system monitoring and control unit (XCU) to monitor voltage, current, power, temperature etc, extend
alarms and provide system control functionality.
NOTE: In Modular On-line AC UPS power system, each module is consist of rectifier and inverter. Construction
of the AC UPS module can be 1 phase input/1 phase output and 3 phases input/3 phases output. Modular
On-line AC UPS power system can be 1 phase input/1 phase output, 3 phases input/1phases output and
3 phases input/3 phases output.
Several measurements are possible: UPS input parameters: voltages, current, frequency, power, power factor (PF) etc.,
UPS output parameters: voltages, current, frequency, power, power factor (PF) etc., battery parameters: voltage, current
andtemperature, etc.
Several controls are possible: to adjust rectifier voltage and battery current, to start a battery test procedure, to adjust
output UPS voltage and frequency, etc.

without interruption in the event that commercial power drops to un unacceptable voltage level.
The AC UPS power system provide uninterruptible 230V/400V; 50 Hz voltage according EN 300 132-3 [2], in period
defined by capacity of installed back-up battery.

NOTE 1: Rectifier and inverter in operation. Inverter synchronized to mains supply but not carrying load current.

Figure 4: Line-interactive AC UPS - normal operation
The main elements of AC UPS power systems are:
• rectifier that converts AC voltage to DC voltage (i.e. 230 VAC/400VAC to DC voltage);
• battery (one or more strings of cells) that stores energy and can power the loads when AC interrupts or
rectifiers fail. There can be test and permanent battery monitoring systems to reduce the failure detection time
and the MTTR;
• protection and distribution (DC bus, breaker, etc.) to power different user loads and discriminate faults;
• inverter that converts DC voltage to AC voltage (i.e. DC voltage to 230 VAC/400VAC);
• Static Bypass Switch (SBS) monitors output and input voltage (mains AC voltage) of UPS, and synchronizes
UPS output voltage to the input voltage, or transfers theinput voltage to the output to supply Current using
equipment;
• External (Manual) Bypass that transfers input voltage to the output to supply Current using equipment, in the
case of UPS failure, UPS service, maintenance, etc.;
• a system monitoring and control unit (XCU) to monitor voltage, current, power, temperature etc, extend
alarms and provide system control functionality.
NOTE: In Modular On-line AC UPS power system, each module is consist of rectifier and inverter. Construction
of the AC UPS module can be 1 phase input/1 phase output and 3 phases input/3 phases output. Modular
On-line AC UPS power system can be 1 phase input/1 phase output, 3 phases input/1phases output and
3 phases input/3 phases output.
Several measurements are possible: UPS input parameters: voltages, current, frequency, power, Power Factor (PF), etc.,
UPS output parameters: voltages, current, frequency, power, Power Factor (PF), etc., battery parameters: voltage,
current andtemperature, etc.
Several controls are possible: to adjust rectifier voltage and battery current, to start a battery test procedure, to adjust
output UPS voltage and frequency, etc.
