2.2.2 Working Modes

2.2.2.1 Normal Mode

When the UPS works in normal mode, the rectifier converts the AC input voltage into the DC voltage, which is then raised to the bus voltage by the power factor correction (PFC) circuit. Then one part of the voltage passes through the DC-DC circuit to charge the battery string, and the other part is converted by the inverter into AC voltage outputs. The two conversions ensure high-precision and high-quality output voltages, protecting loads from interferences such as input harmonics, burrs, and voltage transients. Figure 2-3 shows the conceptual diagram of the UPS working in normal mode.

2.2.2.2 Bypass Mode

If the inverter does not start or is manually shut down after the UPS is powered on, the bypass supplies power to loads. The UPS automatically transfers from normal mode to bypass mode if it detects power unit overtemperature, overload, or other faults that may cause the inverter to shut down. The bypass power supply is not protected by the UPS which means it may be affected by mains outage, and incorrect AC voltage or frequency. Figure 2-4 shows a conceptual diagram of the UPS working in bypass mode.

Figure 2-4 UPS conceptual diagram in bypass mode

2.2.2.3 Battery Mode

If the AC input voltage is not normal, the UPS transfers to battery mode to obtain power from batteries. The inverter then converts the power into AC outputs. Figure 2-5 shows a conceptual diagram of the UPS working in battery mode.

Configuration

Application Scenario

Single UPS

Supplies power to common loads.

N+X parallel system (N represents the number of requisite UPSs connected in parallel, and X represents the number of redundant UPSs.)

Supplies power to important loads in small- and medium-sized data centers. It features high availability and strong transient overload capability.

2 ≤ N+X ≤ 4 (1 ≤ N ≤ 4; 0 ≤ X ≤ 3) For example, in a 3+1 parallel system, three UPSs are requisite and

one UPS is redundant.

Dual-bus system

The dual-bus system is suitable for scenarios where high availability requirements are posed for power supply. The dual-bus system supplies power to important loads in large- and medium-sized equipment rooms and data centers. In addition to advantages of common parallel systems, the dual-bus system also provides outstanding availability and eliminates bottleneck failures, but the configuration of the dual-bus system is complex.

Functions

The monitor display unit (MDU) allows for general UPS operations, parameter setting, viewing of running status and alarms, and so on.

A 1+1 parallel system is a typical configuration. You can set the number of requisite UPSs and redundant ones on the LCD or WebUI.

2.4.1 Single UPS

The UPS5000-A is a high frequency tower-mounted UPS. It uses a unit-level design to handle power functionality, and provides an embedded maintenance bypass switch to ensure maintenance with power on. Figure 2-2 shows the conceptual diagram of a single UPS.

2.4.2 N+X Parallel System

In an N+X parallel system, the mains input, bypass input, and AC output terminals between cabinets are connected in parallel. Energy control modules (ECMs) on each UPS are connected over parallel cables. The parallel connections synchronize the UPS outputs to supply power to loads. If one UPS fails, the other UPSs continue supplying power to loads.

Figure 2-26 shows a conceptual diagram of an N+X parallel system.

Figure 2-26 Conceptual diagram of an N+X parallel system

2.4.3 Dual-Bus System

A dual-bus system consists of two independent UPS systems. Each of these UPS systems in turn consists of one or more UPSs connected in parallel. Of the two UPS systems, one is a master system, and the other is a slave system. This design makes the dual-bus system highly reliable and suitable for loads with multiple input terminals. An optional static transfer switch (STS) can be installed to start the bus synchronization controller (BSC). The UPS systems work in normal mode or bypass mode. Figure 2-27 shows a conceptual diagram of a dual-bus system.
