2-1 FUNCTIONS AND FEATURES

z A True ON LINE design. The UPS insures the critical power protection for your
mission-critical equipment at all times.
z Wide input range of power supply that reduces discharge rate of battery.
z A smart charger design for auto equalizing charge to shorten charging time.
z Equipped with RS232 port and Dry-contact interface, using the power management
software "UPSentry Smart 2000" allows near-end and far-end UPS monitoring
management.
z Automatic detection of 50/60Hz field input frequency
z With excellent performance. Input current using active input power factor correction and a
high-frequency inverter with pulse width modulation.
z Optional isolated output transformer: Provides isolation and multiple output voltage.
z Start-on-battery capability for powering up the UPS even if utility power is not available.
z Optional SNMP interface card is an optional accessory for network communication.
z Implementing diagnostic test and LCD message display by using microprocessor
technology can provide detailed information on operation status.
z Manual and static bypass switch forms. Allowance for switching to the main power supply.
z Static bypass supply circuit incorporates functions such as surge suppression and EMI filter.
z Remote emergency power off (REPO): Emergency shutdown control through the remote
emergency power-off (REPO) port.
z Auto recovery function of inverter:
y
When the AC power is restored after a low battery shutdown, the UPS inverter will
automatically restart.
y
Automatic transfer to inverter output from static bypass after overload condition is
cleared.
z Alarm cancel facility to switch off the audible alarm and indicative lights still lit in the event of
long BACK-UP periods.
z External battery cabinet can be used for extending operation time of battery mode.
z Operation of "ECONOMY mode" (Optional): When input voltage is within the range of rating
voltage (±10%), the UPS is working in the bypass mode for higher efficiency. Otherwise the
UPS will be switched to inverter mode.
z Auto detection for voltage in bypass mode: The protection range is +15%~ - 20%. When
the bypass voltage is beyond protection range, the UPS will not supply output power to the
load.
z Auto detection and display for normal operation of fan.
