DC48V Rack Mount Rectifier High-Capacity M45D65B 220VAC Single Phase

1. Rack Mount Rectifier Overview

M45D65B is a 19-inch sub-rack for hybrid power system , with 2U height compact design to meet critical application needs of fiber and microwave transmission, access device, switch.

The system’s maximum power is 90A, with AC input/DC input/battery/load MCBs. The cables are front accessing with MCB and busbar. This power system supplies power to -48V communication

Equipment.

2. System Parameter

3. Telecom Rectifier Quick Details

• Standard 19-inch width for versatile usage
• 2U height compact design, saving space and installation costs
• Front operation and cable access for convenient maintenance
• Advanced battery management for prolonged battery life
• Various communication ports for flexible networking and remote monitoring
• Hot pluggable rectifier and controller for easy online maintenance
• Wide input voltage range (85-300Vac) for adaptability to power grids

4. Working Principles

(1) AC input: Startup rectifier module after AC powered-on, outputs -48Vdc, at the same time charge the battery and power the conversion module, conversion module outputs 220Vac.

Under normal conditions, the parameters of rectifier module and distribution unit are all under controll of the monitoring module, operating according to the preset parameters or user’s commands. If AC mains fault,

the battery will power to the system, and continue outputing - 48 VDC and 220 vac, with the discharge of the battery, the voltage of the battery starts to descend, when the voltage is under 43.2 V + / - 0.5 V,

the monitoring module send battery under-voltage signal and close the load output directly, then the power system will stop working. When external AC mains recovers,

the system will normally work again. (All above monitoring data are system default values and can be reset by user)

(2) -48V input: No AC current or no AC be connected, access external power -48V to -48V load port, startup monitoring and conversion module, 220Vac output.

Wiring methods:

Ø Remove the cable insulation with wire stripping pliers. The exposed length of the cable core shall not be less than 10 mm.

Ø Press the button above the terminal with the screwdriver, insert the cable, release the screwdriver and complete the cable connection.

Ø With handle gently pull cables, to ensure that the cable does not fall off.

8. Installing Subrack

Install the subrack to the 19-inch rack, as shown in Figure below.

Ø Step 1,Remove the plug from the package.

Ø Step 2,Push the plug into the 19-inch rack

Ø Step 3,Install the fixed screw (if the mounting hole of the plug frame ear does not correspond to the position of the floating nut of the frame, it needs to be adjusted according to the actual installation).

Install Rectifier module

Ø Step 1,Take out the module from the package.

Ø Step 2,Hold the module handle on the front panel and put the module onto the slot.

Ø Step 3,Push the module module slowly to the front panel of the module and flush with the power

distribution panel.

Ø Step 4,Tighten the fixing screw on the module panel so that the module does not come off.

9. Packing and Shipping

Package use free fumigation woodcase which is suitable for export. This package is anti moisture, anti impact and srong to ensure safe transportation.
