Bi-directional DC to DC converter:
Features：
1.Bi-directional Dc Power Supply operation mode
The equipment has five operation modes: constant voltage, constant voltage current limiting, constant current, constant power and constant resistance. The operation parameters of voltage, current and power can be set, and the power protection parameters can be set at the same time
2. Control mode selection function
The equipment can set the control mode of the equipment through the operation interface, including local control, communication control, external analog control and default control mode
(1) Local control function
Through the touch screen, control operations such as power operation parameters, operation, stop and fault reset of control equipment can be set. It can also view various parameters of equipment operation and other operation records.
(2) Communication control function
The power operation parameters can be set through the communication software or communication command to control the equipment operation stop, fault reset and other control operations, and the equipment operation parameters and operation records can also be viewed through the touch screen.
(3) External analog control
Control the operation / stop, fault reset, voltage and current regulation of the equipment through the external analog interface, and monitor the power supply voltage, current, operation status and fault status.
(4) Default control
In this control mode, the power supply equipment can be operated through panel operation, communication control and external analog control.
3. Emergency stop function
The power supply equipment has emergency stop function. In case of emergency, it can stop the power output through the emergency stop button, communication interface and external control interface on the operation panel.
4. Protective device
The power supply equipment has input protection, output overcurrent protection, output overvoltage protection, power device overtemperature protection.
