HOW WE MAKE THE SYSTEM

RIDEX REQUIRED TOOLSTorque controlled screw driver

Wire stripper and cutter

Nut Runner

Spanner Set

Combinational pliers

Spanner for Ring Nut

Duster (6 inches x 6 inches)

Loctite (247)

Glass cleaner

STEP 1-Open the Front Panel of the systemFront View of cabinet

STEP 2-Open the back Panel of the system

STEP 3-Place the system motherboard on the system cage

STEP 4-Install the system cards in the system assembly as per the configuration.

STEP 5- Place the back Panel of the system on the flat top table and Fix the thermal pad on the back

STEP 6-Place the FCBC card on top of the thermal pad and put the aluminum cover

STEP 7- Install the 3 pin AC Filter along with Gasket from the inner side of the rear panel of the system cabinet. Install the AC On/Off switch along with waterproof Cap . Install the AC fuse holder on the cabinet and install the AC Power LED on the Panel as well DC also

FOR DC FOR AC

STEP 8- Install the Battery PWR Harness Connect the Earth Wire from Earth terminal to the system Motherboard. Install the AC PWR Harness Connect the FCBC to Motherboard Harness between the FCBC and the Motherboard.

STEP 9-Tighten the back panel of the system by tightened the 10 Nos.

Assembly of Front PanelSTEP 10-Required hardware VFD Glass

Fix the 4x4 Numerical keypad rubbers on the 4 x 4 keypad PCA .

Fix the 2x8 functional keypad rubbers on the 2 x 8 keypad PCA .

Place the 2 x8 and 4x 4 keypad cover on the 2x 8 4x 4 keypad mounting plate.

INTRODUCTION:

Uses like one of the input power supply . {Like 12V,24V,48V Dc or 230 V AC voltage }

FCBC have also battery bank when AC supply is present

The voltage proportional to the peak value of Ac input

INPUT : 220V AC/12V,24V,48V DC

OUTPUT : 48 V DC

Power Backup : 12V,24V,48V battery bank

System Efficiency at full load : More than 85%

WORKING

FEATURE Output current is Programmable

Over voltage is possible

Compatible with all major battery types

When Ac offline than automatically Dc will be on

Integrated thermal protection

PSU(Power Supply Unit)PSU board :

Plug-in supply board

redundancy option

operates from 36V-72VDC input.

PSU is powered from 48V DC

PSU card is a DC-DC converter

which converts -48V DC input to +5V, -24V, -48V and +48V as per other cards requirement.

We use two PSU Card on a system ,when the working PSU card fails, the protection card takes over automatically. Input fusing and output over current protection are provided as safety features
