Product Description

Product Description

 

Introducing our pioneering DC Panel, an engineering marvel crafted for seamless operation in large, medium, and small power generating plants or substations. This extraordinary panel ensures a steadfast DC power supply for numerous essential functions, including ON/OFF operations, relay protection, automatic control, and lighting for high voltage switches, regardless of whether conditions are normal or faulty. Widely recognized for its outstanding reliability, it remains an indispensable auxiliary power source in both substations and power plants. This cutting-edge panel features a compact design, exceptional efficiency, and advanced technical specifications. Its revolutionary module design incorporates n+1 heat redundancy backup, guaranteeing unmatched reliability. Embracing the avant-garde Resonant voltage dual-loop control resonant switch power source technology, it facilitates four remote operations and is equipped with standard RS-485 and RS232 interfaces, ensuring seamless automation that transcends conventional power sources in both effectiveness and innovation.

 

 

 

 

Full voltage auto drop

It can automatically switch on/off according to the voltage for closing operations, by use of stepless voltage drop device, or
voltage step drop device, reliably and securely

Centrally monitor and control function

Central monitor device ordinate or control the running parameters/status of each part in DC panel, meanwhile collect the parameters of each function module and upload to host machine, transfer the command from the host machine. The structure designed as building brocks, the panel can supervise the input AC source voltage, current, of two loops, work mutually as the main and standby source for auto-switching n/off. ordinate or control the current and voltage of control busbars and closing busbars; battery voltage, battery discharging current, insulation parameter, supervise the operating status of the closing switch control switch, battery fuse, detection of the insulation for outgoing line (option), toured inspection of battery (option), monitoring ambient temperature

Multi-stage protections

Surge protector to prevent input over-voltage: output over-voltage protection; output current limiting protection; short circuit protection; module shunt protection; over-temperature, over-current protection, all of these can improve the safety and reliability of operation

Temperature compensation

According to the data provided by the battery factory, select the temperature compensation center and the coefficient
automatically adjust the charging voltage, to meet the requirement of battery charging

Alarm function

After parameter set, it can perform different alarm functions, including under-voltage of control busbar, under-voltage of battery group, insulation abnormality, output switching status

N+1 Redundancy design

Change the qty and capacity of power source modules, to realize the free combination of output scheme of panels, to match different battery capacities, from 10Ah-3000Ah. Meanwhile, because this design executes n+ 1 redundancy arrangement when the capacity is small, it still can realize 1+1 standby.

Communication function

Through the selection of interface, it can shift the communication protocol between CDT and MODBUS. Two communication ports RS-485 and RS-232 to be selected for four remote operations

Battery-free of maintenance

Valve Regulated Lead Acid Battery, free of maintenance, is utilized, able to work securely and safely. It does not need to add acid or water. The smart controller can shift between average charge and float charge according to the presetting
