Understanding UPS Operation 5.1 Looking Inside the UPS System 5 The Powerware 9335 is a continuous duty, solid-state, transformerless (at 480 VAC) three phase, true online system that provides conditioned and uninterruptible AC power to the UPS systems output. The UPS supports process control, data processing, telecommunications/PBX, and research equipment.
Maintenance Bypass Switch IA1 Contactor K4 Static Bypass Switch EMI Filter Contactor K1 Input Filter Rectifier Booster Inverter Output filter Output Contactor K2 Output Switch IA2 N EMI Filter EMI Filter Battery Charger Battery Fig. 5–1.
5.2 Normal, Battery and Bypass Modes The UPS system functions automatically to supply AC electrical power to the critical load. There are four standard operation modes. • In Normal mode, the critical load is supplied by the inverter, which derives its power from rectified utility AC power. In this mode, the battery charger also provides charging current for the battery, if needed. • In Battery mode, the critical load is supplied by the inverter which derives its power from the battery DC power.
5.2.1 Normal Mode Figure 5–2 shows the path of electrical power through the UPS system when the UPS is operating in Normal mode. Normal Mode IA1 Static Switch K4 Input Filter K1 Rectifier Booster Inverter K2 IA2 F1 Breaker Contactors Battery Charger Switches Closed Main Power Trickle Current Open Battery Breaker Energized De-Energized Battery Figure 5–2.
The DC boost converter derives power from the unregulated DC rectifier and produces a higher, stable DC voltage and current source for the inverter. A fixed system neutral is also carried through the boost converter to allow full support of single phase AC loads from any phase of the inverter output. The output neutral of the system is connected to the required neutral, both from the main utility supply and the bypass supply and should never be bonded to protective earth ground at the UPS output.
5.2.2 Bypass Mode The UPS automatically switches to Bypass mode if it detects an overload, load fault, or internal failure. The bypass source supplies the commercial AC power to the load directly. Figure 5–3 shows the path of electrical power through the UPS system when operating in the Bypass mode. CAUTION: The critical load is not protected while the UPS is in the Bypass mode.
contactor and together are wired to enable the inverter and rectifier to be bypassed when this path is active. The static switch, as an electronically controlled device, can be turned on immediately to pick up the load from the inverter. The backfeed protection contactor is normally always closed, ready to support the static switch unless the bypass input source becomes unavailable.
5.2.3 Battery Mode The UPS transfers to battery mode automatically if a utility power outage occurs, or if the utility power does not conform to specified parameters. In Battery mode, the battery provides emergency DC power that the inverter converts to AC power. Figure 5–4 shows the path of electrical power through the UPS system when operating in Battery mode.
While in battery mode, the UPS will enunciate an audible horn, indicate the status change on the front panel display with the message “MAINS NOT OK”, and make an entry into the alarm event history. As the battery discharges, the boost converter and inverter constantly make small adjustments to ensure a steady output. The UPS will remain in this operating mode until the input power to the rectifier is again within the specified voltage or frequency acceptance window.
5.2.4 Maintenance Bypass Mode An internal maintenance switch (IA1) is used to safely supply utility power to the system output during periods of maintenance or repairs. Before this switch is used, the system should be transferred to bypass. This switch has two positions: “O” (OFF) and “l” (ON). When switched to “l” (ON), the bypass source supplies the commercial AC power to the load directly.
5.3 Functional Description The UPS is an online double-conversion unit with a series power train. An uncontrolled rectifier feeds a boost converter, which in turn powers the inverter. The internal static bypass utilizes a static switch and an independent maintenance bypass switch is also included internal to the UPS cabinet. The unit input must be 4-wire in (plus ground) at the rectifier and 4-wire in (plus ground) at the bypass.
or constant voltage mode (temperature compensated, available as an option) based on battery condition. All batteries used in conjunction with the Powerware 9335 are external to the UPS cabinet. The internal charger charges the entire battery system, with a maximum current as indicated in Chapter 13, “Product Specifications”. Note that the higher the battery capacity, the longer the recharge time required to fully recharge the batteries. 5.3.
6 Operational Controls and Features 6.1 General The UPS system should function automatically and require very little attention during normal operation.
