Zippy R3G-6650P - Manual (Page 3)

1.1 INTRODUCTION
First of all, thank you for purchasing R3G Series – 2 + 1 Redundant power supply,
the R3G is a 2+1, Hot-swappable/Hot-pluggable, Redundant power supply set, it
consists of:
(1) complete metal frame (nickel-plated)
(2) 2 + 1 compact size power modules
(3) backplane board
The R3G Series hot swappable redundant power supply offer a maximum 650
watts of output power. They provide Active Power Factor correction (PFC)
feature at full range AC Input complies with IEC 1000-3-2/3 for critical
applications.
The power unit’s size is compact each power modules built an interior 40 m/m
ball bearing DC fan for better ventilation. Particularly an 80 m/m DC Fan built
on the rear side of the whole system to make sure a safe working unit. Each
power module has designed with 6 outputs including +3.3V, +5V, +12V, -12V,
-5V & 5VSB circuits and higher current availability based on Intel ATX12V /
EPS12V standards. All you can see on the backplane board is just passive
components and this is the key point to a greater Power Supply MTBF.
The unit features a warning sub-system, including LED display, buzzer alarm,
TTL signal, I
2
C interface device ( optional feature ) etc., at the same time, it
guides user the fast way to find out the power supply Good or Fail condition.
When all the power modules are at normal condition, it balances the load share
through its parallel design and results the power system increase reliability.
To really discover the power and ease in using these products, we recommend
that you read through this manual carefully.
