function UPS introduction Long-term online floating charge to battery, high charging efficiency,
battery can saturate to more than 90%, cauto-stop harging when it's full,
prevent over charging. Effectively extend battery life, AC/battery auto switch,
no switch time, no need human guard, Cold-start, when there is no AC input,
can use battery start UPS, Meet the user's emergency needs

note 1. All parameters NOT specially mentioned are measured at 230VAC input,
rated load and 25°C of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using
a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance: includes set up tolerance, line regulation and load regulation.
