Performance characteristics
1. stabilized voltage and current. Digital keyboard operation, voltage, current from zero to rated value adjustable, output voltage and current value set in advance. This product can work in the fixed voltage (CV) mode or the fixed current (CC) mode, the working mode switches automatically, and indicates the condition of the working mode via the LED. When CV-LED lights up, the power works on a fixed voltage mode, and when the CC-LED is on, the power is working in a fixed current mode.
2.High precision, low ripple. The DC power supply is controlled by peak current, and has good load and power regulation rate, and the output voltage and current precision are high. The output is equipped with a multilevel filter, and the output ripple is low.
3.High efficiency. The soft switching technology with international advanced level makes the power supply high efficiency, low noise and high reliability; the efficiency of the whole machine is higher than 95%.
4.The protection function is complete. There is an overload protection circuit inside the power supply to ensure the normal operation of the power supply equipment and the safety of the load.
5.Output display. The voltage and current are displayed with high precision LED digital meter.
6.Digital control. All digital control, voltage and current can be realized through digital programming; all the calibration is digital calibration, stable and reliable.
7.Remote control function. The power supply is equipped with RS485 interface and can communicate with the computer through the MODBUS protocol. It supports multi machine communication and reliable verification. Each 485 interface supports up to 255 power supplies and realizes monitoring at the same time. The computer can monitor all the parameters and states of the power supply remotely. The upper computer can realize remote parameter setting and control function according to authorization.
