Zippy R2G-5420P4V - Manual

1.1 INTRODUCTION
First of all, thank you for purchasing R1G series redundant power supply.
The R1G series is a N+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 N+1 pieces power modules. The number N+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. 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 R2G/R3G series offer a warning sub-system, including LED display, buzzer alarm,
TTL signal, and I
2
C interface device (optional). 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.
