1.1 INTRODUCTION
First of all, thank you for purchasing MRT/MRW Series – PS/2 size Mini
Redundant power supply. The MRT/MRW Series are 1+1, Hot
swappable/Hot-pluggable/Redundant power supply set, it consists of:
(1) Complete metal frame (nickel-plated)
(2) Compact size (real PSII form factor) 1+1 power modules
(3) Backplane board
The MRT/MRW Series of hot swappable redundant power supply offer
maximum 300/320/400 watts of output power. The MRT/MRW series provide
Active Power Factor correction (PFC) at full range AC Input that complies with
IEC 1000-3-2 for CE norms. The units are compact size as PS/2 form factor and
all the power modules are built interior 40X40X20 mm /40X40X28 mm ball
bearing DC fans for better ventilation. Each power module has been designed
with +3.3V, +5V, +12V, -12V, -5V & 5VSB circuits. All you can see on the
backplane board are passive components and this is the key point of greater
MTBF.
The units also provide a warning sub-system, including LED display, buzzer
alarm, TTL signal etc.. At the same time, it also indicates the status of the power
system and DC fans.

When all the power modules are at normal condition, it balances the load share
through its parallel design and results in the increasing reliability of the power
system.
In order to use the power supply more effectively and safely, we suggest that
you read through this manual carefully in advance of the installation and any
operation.
