High reliability :
In order to cope with the complex application environment, to maintain the excellent performance of products, we continue to pursue strong design and excellent stability.
1. Perfect protection circuit, overload, polarity protection, over voltage protection, over current protection, over temperature protection, ensure the safety of power supply.
2. The utility model has the function of simultaneous protection of voltage and current, and the power supply can automatically switch between the CC/CV according to the load condition, so as to improve the adaptability of the power supply to the load.
3. Efficient cooling system, according to the temperature of the system, automatically adjust the speed of the cooling fan, which can reduce the noise of the system, but also can improve the power density of the system.
4. Innovative design of the screw rod terminal, especially suitable for large current output, easy to operate, reliable and durable.
5. Specially designed high strength chassis, with plastic sheath before and after the effective protection of equipment to extend the system use time.
High performance:
Years of research and development in the field of power supply and production experience, the use of innovative design and advanced circuit structure, improve product performance.
1. The use of low dropout linear regulator and multi-level output filter can effectively reduce the power supply ripple and noise, can achieve the same capacity linear power supply indicators.
2. Active power factor correction circuit with high power density, high power efficiency, high power factor.
3. In the switching mode using a linear adjustment mode, so that the switching power supply can be adjusted from 0V start.
4. The remote feedback terminal can be used to offset the voltage output error caused by the loss of the line, and to ensure the precise control of the output voltage of the power supply.
ulti function, easy operation:
With constant current and constant voltage automatic switching function, according to the load automatically switch
1. Support SCPI programmable instrument standard instruction, equipped with RS232 interface, Easy to form ATE system with other programmable instruments.
2. The operation interface conforms to the principle of human engineering, and the software design takes full account of the needs of customers, The operation is convenient and quick
3. Convenient and fast operation and setting interface, high speed adjustment knob and digital key input.All electronic calibration. Need’t to Remove case.
