1. INTRODUCTION (for standard models: SS-650/1000 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 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.
