Zippy R2T-6460P - Manual (Page 3)

1.1 INTRODUCTION
First of all, thank you for purchasing MR3 / R3U / R2T Series – 2 + 1 Micro
Redundant power supply, MR3, R3U AND R2T have the same main structure
and functions, the difference is on the shape and dimension, MR3 is similar to
PS/2 form factor, R3U is suitable for 3U chassis, R2T will be used in the front
side of 2U chassis, for each detail drawing, please refer to the section 1.6. .
The MR3 / R3U / R2T is a 2+1, Hot-swappable/Hot-pluggable, Micro Redundant
power supply set, it consists of:
(1) complete metal frame (nickel-plated)
(2) 2 + 1 compact size power modules
(3) backplane board
The MR3 / R3U / R2T Series hot swappable micro redundant power supply
offer a maximum 460 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 in MR3 only ) 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.
