1. INTRODUCTION

First of all, thank you for purchasing RVN4 Series High-Density Redundant power supply for

4U~8U chassis.

The RVN4 is a 3+1, Hot-swappable/Hot-pluggable, High-Density Redundant power supply set,

it consists of:

(1) complete metal frame (nickel-plated)

(2) compact size (smaller than PSII form factor) 3+1 power modules

(3) backplane board

The RVN4 Series of hot swappable high-density redundant power supply offer a maximum

2000watts of output power. The RVN4 series provide Active Power Factor correction (PFC) at

full range AC Input complies with EN 61000-3-2/3 for critical applications.

The power unit’s size is compact which smaller than PSII form factor and both power modules

built two interior 38X38 m/m ball bearing DC fans. Each power module has designed with 5

outputs including +3.3V, +5V, +12V, -12V & 5VSB circuits and higher current availability based

on Intel ATX12V / EPS12V standards. All you can see on the backplane board is just passive

components and this is the key point to a greater Power Supply MTBF.

The unit including LED display, buzzer alarm, TTL signal, etc.

When all the power modules are at normal condition, it balances the load share through its

parallel design and results the power system increase reliability.

To really discover the power and ease in using these products, we recommend that you read

through this manual carefully.
