1.1 INTRODUCTION 

 

First of all, thank you for purchasing M1S2 series redundant power supply for 1U. 

 

The M1S2 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 M1S2 series redundant power supply offer a maximum 400/500 watts of output 

power. 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 5 outputs (+3.3V, +5V, 

+12V, -12V, and +5Vsb) circuits, and compliant to ATX12V. All you can see on the 

backplane is just passive components and this is the key point for longer MTBF. 

 

The M1S2 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 and DC fan 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.
