Zippy MRT-6320P User Manual

1.1 INTRODUCTION

First of all, thank you for purchasing MRT series redundant power supply.

The MRT series is a 1+1 hot-swappable / hot-pluggable redundant power supply. It
consists of,

1) complete metal frame

2) compact size power module

3) backplane

The MRT series hot swappable redundant power supply offer maximum 300/320
watts, and provide Active Power Factor correction (PFC) at full range AC input that
complaints to EN 61000-3-2 for CE norms. The power module is in compact size, and
built-in a 40mm ball bearing DC fan for better ventilation. Each power module is
designed with 6 outputs (+3.3V, +5V, +12V, -5V, -12V, and +5Vsb) circuits. All you can
see on the backplane is just passive components and this is the key point for longer
MTBF.

The units also 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.

1.2 PACKING

Your MRT series should consist of the following,

a) MRT series x 1
b) Accessory pack x 1
c) Product Manual x 1
