Community College of Allegheny County OCS Security Camera System Pittsburgh, PA
d. Frequency: The UPS shall auto-sense input frequency when first powered up and shall operate within the following frequency specifications. UPS shall be capable of cold start with default frequency of 60Hz. Once started the frequency operating window shall be 40-70Hz. Three frequency settings shall be available in the Liebert GXT5 Configuration program: Auto frequency sensing (factory default setting), 50Hz frequency conversion and 60Hz frequency conversion. e. Input Power Factor: >0.99 lagging at rated load. f. Input Current Harmonic Distortion: THD shall be less than or equal to 3% at linear, full load operation. THD shall be less than or equal to 5% at nonlinear, full load operation. g. Input Current Ratings

h. Inrush Current (initial startup, no load): The UPS shall have a maximum inrush current of 6 times the full load peak input current. i. Surge Immunity & Protection: UPS shall conform to ANSI C62.41, Category B. j. Surge Protection: MOV (Metal oxide varistors) ratings shall be 190V, 80 Joules minimum connected L1-L2, L1-G and L2-G. 2. AC Output, UPS Inverter a. Voltage Configuration: 120/208VAC at 120 degrees phase angle factory-default, 50/60Hz, single-phase, 3-wire-plus-ground (L-L-N-G). Optional output voltage settings shall be user-adjustable. Output options shall include 100/200, 110/220, 115/230, 120/208, 120/240, 125/217VAC. b. Voltage Regulation: Voltage regulation shall be ± 1% steady state. c. Frequency Regulation: ±3.5Hz synchronized to bypass. ±0.1Hz free running or on- battery operation. d. Frequency Slew Rate: Slew rate shall be 1.0Hz per second maximum. The slew rate shall be user-selectable for non-parallel units, options to be 0.2, 0.5, or 1.0Hz/S. For parallel units, the slew rate shall be fixed at 0.2Hz per second. e. Voltage Distortion: <2% total harmonic distortion (THD) typical into a 100% linear load, <5% THD typical into a 100% non-linear load. For parallel units, <3% total harmonic distortion (THD) typical into a 100% linear load, <6% THD typical into a 100% non-linear load.
