Typical Holdup Times
The table below shows some typical holdup times with a computer load. Please note that actual holdup times with your equipment could vary. (A typical desktop PS or Macintosh draws between 200 and 300 watts).

UPS Technical Specifications

Input	100-130Vrms, 60±GHz, sinusoidal
UPS Output (on battery)	105-130Vrms, 60 1Hz, pulse-width modulated, modified sine wave. 250 watt maximum (UPS-3600). 300 watt maximum (UPS-4500) 360 watt maximum (UPS-4500). 500 watt maximum (UPS-7200)
Transfer from AC to Inverter	Brownout threshold: 97±2Vrms. Over voltage threshold: 133±3Vrms. Transfer Time: 1 ms maximum, phase locked to the AC
Transfer from Inverter to	The line voltage has to stabilize to between 100 and 130Vrms for at least 2 seconds in order to transfer back to AC Transfer Time: 1 millisecond, phase locked to the AC.
Surge/Spike Protection	AC hot to neutral, AC hot to ground &AC neutral to ground are protected by 3 MOV's (metal oxide varistors), each rated at 150W &6,500 amps of shunt current (8 x 20us).
Battery &Charger	Two long-life, leak proof, sealed lead-calcium batteries, each rated at 12Vdc, 7Ah provide 168VAh of capacity Typical recharging time is 5-6 hours to return 90% of capacity
EMI/RFI Filter	6 amp power line filter provides 50dB of attenuation (line-to-ground, 50W) at 30 MHz (UPS-4500, UPS-5500 &UPS-7200 only). 1.6mm thick steel case blocks radiated EMI/RFI noise
Safety and Reliability Features	Designed to meet UL/CSA/IEC standards of approval External mains fuse protects all AC circuits. Internal fuses protect all DC circuits Internal overload circuit disconnects the load if the maximum power of the UPS is exceeded for more than a few seconds. Battery protection circuit prevents complete drain and damage of battery under most circumstances. Durable, all steel case withstands transport in hostile environments, and installation and operation in any indoor application.
Size/ Weight	Width - 16"; Depth - 12"; Height - 3 1/8" UPS-3600 and UPS 4500: 30 lbs UPS-5500 and UPS 7200: 36 lbs
Operating Environment	Operating Temperature: 0C to 40 C (32F to 100F) Humidity: 0 to 95%, non-condensing. Estimated MTBF: 10 years (5 years for batteries).
Warranty	Two years limited warranty, parts and labor (except for batteries). Battery manufacturer's warranty on batteries. Extended warranty available.
