Instruction Manual

1.1 INTRODUCTION
First of all, thank you for purchasing DR1M series redundant power supply for 1U.
The DR1M 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 DR1M series redundant power supply offer a maximum 220 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 6 outputs (+3.3V, +5V, +12V,
-5V, -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 DR1M 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.
