Zippy MRP-6420P - Manual

1.1 INTRODUCTION
First of all, thank you for purchasing MRW/MRP series redundant power supply.
The MRW/MRP 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 MRW/MRP series hot swappable redundant power supply offer maximum
350/400/420 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.
