1. INTRODUCTION (for standard models: SS-1200/1500/2000/3000 only)
1.1 Overview:
The series UPS is an advanced Line-Interactive Uninterruptible Power System
which produces pure sine wave power to your equipment; unlike the traditional
off-line UPS, the series provide very short transference when blackouts happen, and
zero transference from AC mode to battery mode or from battery mode to AC mode.
The voltage regulation performance of series is similar to an On-line UPS; however,
the series provide efficiency over 98% under normal power condition. Two charge
modes, quick charge and trickle charge, are provided to maintain the batteries in the
best condition.
1.2 Battery replacement warning
The self-test function (by pushing the button) will inform you with an alarm
when the batteries are weak and require replacement.
1.3 DIP Switches
The DIP switches allow you to adjust the UPS for different line voltages and
frequencies in different areas. It also allows you to enable the green power
function to shut down the UPS automatically if the load is less than 25W, and
then to extend the battery life.
1.4 Communication interface
A communication interface port for sensing input voltage, output voltage, battery
capacity, output power level, and UPS statuses are provided; through this port, you
can remote control the UPS for turning on and off by customized schedule and
setting the auto-test procedure.
