1.1 INTRODUCTION

First of all, thank you for purchasing MR3 series 2+1 mini redundant power supply.

The MR3 series is a 2+1 hot-swappable / hot-pluggable redundant power supply. It

consists of,

1) complete metal frame

2) compact size power module

3) backplane

It is composed of 2+1 pieces power modules. The number 2+1 stands for there is an

extra power module to backup the system if any power module fails.

The power module is in compact size, and built-in a 40mm ball bearing DC fan.

Particularly, a 80mm DC fan is built unto the rear side of the power system to offer

better ventilation and reliability (not available for MX3 series). Each power module is

designed with 6 outputs (+3.3V, +5V, +12V, -5V, -12V, and +5Vsb) circuits, and

compliant to ATX12V / EPS12V. All you can see on the backplane is just passive

components and this is the key point for longer MTBF.

The MR3 series offer a warning sub-system, including LED display, buzzer alarm, TTL

signal, It guides user the fast way to find out the power supply status.

When all the power modules operate normally, it balances the load share through its

parallel design, which increases the reliability of power system.

To really discover the power system and ease in using it, we recommend you to read

through this manual carefully.
