1. ET48300-004 Quick Details:

ET48300-004 consists of two modules:

Rectifier module (MR483000MG1)*6

Photovoltaic module

Battery breakers : 2×125A/1P

Load breakers

LLVD:32A/1P×2+40A/1P×2+63A/1P×3

BLVD:6A/1P×2+10A/1P×2+16A/1P×2

2. ET48300-004 System Configuration Description

ET48300-004 sub-rack power supply, 5U height compact design to meet

critical application needs of fiber and microwave transmission, access

device, switch. The system maximum power is 18KW, with AC/battery/load

MCBs. The cables are front accessing with MCB and busbar.

l Standard 19-inch width which has the advantage of wide use

l 5U height compact design, space and installation cost can be saved

l Front operation and cable accessing, good-looking and safe maintenance

l Perfect battery management, prolongs the life of the battery well provide

various communication ports, RS485, internet port, dry contacts, etc.

which enables flexible networking and remote monitoring

l Rectifier and controller are hot pluggable, easy and quick on-line

maintenance

l Wide input voltage range(85-300Vac) the power grid is adaptable

3. ET48-60KW consists of distribution unit, rectifier module, conversion module, monitoring module. The configuration is optional, as table below:

4. Payment & Shipping Terms:

5. Two operating methods:

(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.

Temperature compensation function is on by default, which can be activated or forbiddened by user’s command if necessary. Operation temperature ≥55℃, the power output of the power supply will be linearly reduced (@65℃,output power will be 1300W).
