Long life rated 8-10 year @25°C

-15 to +50 °C charge rated and -20 to +60 °C discharge rating- order 2 sets PSRBC3303H for cabinet

Interface Port(s)

USB and 8 pin terminal block (no DB9) standard and available SmartSlot for optional SNMP Ethernet Network card (PS9059)- Use Multilink software (supplied) or SNMP software to communicate with UPS and capture alarms with USB or Ethernet.

8 pin terminal block – Any mode Shutdown (immediate) and Battery Mode Shutdown (2 minute) inputs.

Also Battery Mode indicator and Low Battery indicator dry contacts (30ma max.).

The purpose of Any Mode Shutdown is to shut down the UPS output by turning off the rectifier, inverter and bypass so that there is no power to the loads. Any Mode Shutdown can be operated locally and remotely, as described as follows:

• Any Mode Shutdown can be performed by shorting Pin1 and Pin2 with external switch (not supplied)

• Battery mode Shutdown can be performed by shorting Pin3 and Pin4 with external switch (not supplied). A battery shutdown signal will not cause an immediate shutdown. It will start a 2 minute shutdown timer. This timer cannot be stopped once triggered. If utility power returns during this countdown, the Liebert GXT3 will still shut down and must remain shut down for 10 seconds. Whether the UPS turns back on when the power is restored depends on the auto-restart setting.

Control panel

LED status display with 5 load indicators and 5 battery bar-charge level indicators

Also On Line LED: On Battery: Replace Battery: Bypass enabled and Overload Indicator LEDs

Audible Alarm -Alarm when on battery: distinctive low battery alarm: on bypass


The PS3300 has surge protection and filters that protect the connected load from power surges,

Electromagnetic interference (EMI) and radio frequency interference (RFI). These features can minimize any surges or interference present in the utility power. The filters also prevent surges or interference generated by the UPS from adversely affecting devices connected on the same branch. Surge immunity IEC 62040-2 2nd Ed.

Input Protection

The UPS has built-in protection against undervoltage, overcurrent, and overvoltage conditions including low-energy lightning surges, introduced on the primary AC source. The 120 and 208 VAC models can sustain input surges without damage per criteria listed in ANSI C62.41 Cat A Lev3. The 230 VAC UPS can sustain input surges without damage per criteria listed in EN61000-4-5.
