Operation

General Description

As double conversion On-line UPS, it can convert clean single-phase power to support your critical system. The diagram of UPS is as shown above.

• Input filter reduces transients and interference from the main
• With PFC AC/DC, AC-power is rectified and regulated to DC power
• DC power is converted to AC in the inverter passing it on to the load

Line-Mode/Battery-Mode

• UPS will operate in Line-Mode that supports power and charge battery while connected to power.
• During a power failure, the UPS will switch to Battery-Mode, in which power is maintained from the battery.
• In case of failure time exceed Battery-Mode duration, UPS will shut down until voltage return to prevent battery discharge.

Free Run Mode

• Free Run Mode provides a wider input frequency range when input frequency does not match the selected range (user adjustable).
• Free Run Mode enlarges input frequency acceptance up to 45Hz ~ 65Hz but fixes output frequency to 50Hz(220V) and 60Hz(110V) with ±0.25Hz.
• Free Run Mode designs for large power variation. It is activated in default and can run with Line-mode simultaneously.

High-Efficiency Mode

• High-Efficiency Mode designs to minimize power loss and power consumption. Whenever power is stable, UPS will automatically switch to bypass for efficiency.
• When any irregularity is detected, Line-Mode will reactivate immediately. Switching occurs when  the input voltage is outside ±10% of nominal (±15% selectable), input frequency is outside of ±3Hz, or when no input line is available.
• You can also activate this mode from the LCD panel. Refer to UPS configuration.

Diagnostic Test

• The diagnostic test automatically executes to check and report UPS status. While the advanced battery management system monitors the conditions of the batteries, it sends early warnings if a battery replacement is needed. The test performs every 30 days of normal operation.
• Diagnostic tests can also activate by manual control.

Generator mode

• This mode designs for highly unstable power. In this mode, UPS normal operation will not transfer to bypass to prevent load damage and frequent battery discharge. UPS will also fix output frequency to 50Hz(220V) or 60Hz(110V) with ±0.25Hz. Users can  set the UPS to bypass/shutdown whenever UPS malfunction occurred. Generator Mode can activate from the LCD panel too.

System Configuration

• The UPS device and battery make up the system. Depending on site and load requirements, certain additional options are available as tailored solutions. Please consider the following when planning your UPS system:
• The total demand for the protected system shall dictate the output power rating (VA). When measuring demand, please allow a margin for future expansion and calculation error.
  • Battery-mode duration needs dictate the battery size. If the load is less than the UPS nominal power rating, then the actual backup time is longer.
  • The following options are available:
  • Connectivity options (Relay card, SNMP/WEB card)
  • External battery packs
  • Transformer cabinets
  • Maintenance
  • bypass switches
