AC Output
Voltage Regulation: Regulates steady state output voltage to ±5% of nominal on line and on battery at the default
parameter settings. Exceeds the CBEMA voltage regulation guideline for computing equipment
under any line, load or battery condition, excluding bypass mode.
Sine Wave Power:
Output Frequency: 50 Hz or 60 Hz ±0.15 Hz on battery. Same as line on AC line within programmable limits. (See
Section 303, parameters 13-17).
Output Protection: Provides automatic current and overvoltage protection. The unit has high AC and low AC output
voltage alarms, as well as circuit breaker warning/shutdown and overload alarms. Optional output
receptacle panels protected by fuses or circuit breakers.
Lightning, Surge, and Noise Protection
Lightning/Surge Protection:
Surge Voltage Let-Through:
Surge Suppressor Rating:
Noise (RF) Isolation:
Isolation:
Environment
Ventilation: Air around the UPS must be free of dust, chemicals, or other materials that corrode or contaminate.
Air must be free to move around the UPS. Do not place the UPS in a sealed room or container.
Operating Environment: 0° to + 40° Celsius (+32° to +104° F). 0 to 95% relative humidity (noncondensing). Battery
High Altitude Operation: The maximum operating ambient temperature drops 1° Celsius per 300 meters (2° Fahrenheit
Storage Temperature:
Batteries and Battery Charger
Batteries: Batteries are sealed, maintenance-free, gas recombinant, lead-acid type, specially designed for UPS use.
Nominal battery voltage is 48 VDC. Batteries are UL 924 recognized.
Battery Charger: The standard battery charger is a three-state charger (Maintenance, Constant Current and Constant
Voltage). Recharge time to 85% is 4 to 6 hours typical.
