Wide range input voltage. 3 Steps AVR system. Battery low voltage automatic
shutdown. Over-voltage and under-voltage protection. Excellent microprocessor
control guarantees high reliability. Boost and buck AVR for voltage stabilization. No
load auto shutdown. Off-mode charging. Cold start function. Input Voltage Range:
+/-25% at line input. Output Voltage Range: (on AVR) AVR automatically increase
output voltage 15% above input voltage,if -99% to -25% oh nominal, AVR decrease
out voltage 15% below input Voltage If +9% to 25% of nominal. Real Watt: 300W.
Protection: Automatic self-test & discharge protection, replace battery indicator. Back
up time: 6-30 minutes (depending on computer load). Battery Back up: Slow beeping
sound (once per 2 seconds). Battery Low: Rapid beeping sound (once per 0.5 second).
Overload: Continuous beeping sound. Audible Noise: ˂40dBA (1 meter form surface).
Storage Condition: 1500 meters max.
