SunLight Series UPS User Manual
II. INTRODUCTION
Thank you for selecting this uninterruptible power supply (UPS). To choose the SUNLIGHT series as your
equipment protector was a wise investment. It includes many features to protect your critical equipments.
The SUNLIGHT series UPS system is connected between mains and critical loads , such as computer
systems , telecommunication systems, computerized instruments etc.
The advantages of using UPS:
•
Increased power quality:
The UPS has its own internal voltage and frequency regulator circuits which ensure that its output is
maintained within close tolerances independent of voltage and frequency variations on the mains
power lines.
•
Increased noise rejection:
By rectifying the input ac power to dc power, and then converting it back to ac, any electrical noise
that may present on the input mains supply line is effectively isolated from the UPS output, therefore
the critical load sees only clean power.
•
Power blackout protection:
If the mains power fails, the UPS continues to power the critical load from its battery source, leaving
the load immune from power disturbances.

SUNLIGHT Series Uninterruptible Power Supplies (UPS) are advanced true On-Line Sine wave devices
with static transfer switch which provide reliable, regulated, transient-free AC power to sensitive
equipment.
Since the UPS is a true On-Line system, conditioned power is provided continuously to the connected
equipments. Unlike standby power systems, the UPS is constantly regulating and filtering the output
power. When incoming power is interrupted, the UPS protects the computers instantaneously without any
transfer time.
The SUNLIGHT Series
has high non-linear load capability (i.e. Crest Ratio 3:1) and this is suitable for
powering special loads such as switching power supplies or highly capacitive inputs like computers.
The system's static transfer switch (STS) provides by-pass power as its standby source. During an
overload condition, the S.T.S will switch the customer's load over to the bypass line with no interruption.
