1. Model: IMP-425A/AP, IMP-525A/AP, IMP-625A/AP, IMP-825A/AP, IMP-1000A/AP. 2. Output: (1) Voltage (on battery): simulated sine wave at 100V / 110V / 115V / 120V or 220V / 230V / 240V +/- 5%. (2) Frequency (on battery): 50 or 60 Hz +/-1Hz. (3) Voltage regulation (AVR): AVR automatically increase output voltage 15% above input voltage if -9% to -25% of nominal. (4) Transfer time: 4 milliseconds (typical). 3. Input: (1) Voltage: 100V / 110V / 115V / 120V or 220V / 230V / 240V +/- 25% at line input. (2) Frequency: 50 or 60 Hz +/- 10% (auto sensing). 4. Protection & filtering: (1) Spike protection: 1050 joules. (2) Unit input: breaker or fuse for overload & short circuit protection. (3) Overload protection: UPS automatic power off if overload exceeds 110% of nominal at 60 seconds and 130% at 3 seconds. (4) Telephone protection: RJ-11 (1 in 2 out* or 1 in 1 out) compatible jacks for telephone surge protection. (5) Coaxial protection: F1 terminal for cable TV/modem surge protection. (6) Short circuit: UPS output cut off immediately or input fuse protection. 5. Battery: (1) Type: sealed, maintenance-free lead acid. (2) Typical recharge time: 6 hours (to 90% of full capacity). (3) Protection: auto discharge protection. 6. Physical: (1) Dimension WxDxH (mm): 105 x 334 x 168 (4.1" x 13.1" x 6.6"). (2) Input inlet: NEMA 5-15P / IEC 320. 7.
