产品详情

Suitable for application: engine start-up, motor test

Product advantages: small size, light weight, low price, strong impact resistance.

Disadvantage of the product: The output ripple of the linear power supply is larger than that of the linear power supply.

Performance characteristics:

1. Power supply devices adopt a new generation of IGBT, which makes use of the characteristics of high frequency and low loss of IGBT switching mode to complete power conversion. It has the characteristics of small size, light weight, high efficiency and high reliability.

2. Current-mode control uses full-bridge conversion, PWM control and slope compensation technology. It does not need series anti-bias capacitors. It has the advantages of fast dynamic response, strong anti-impact load capacity and reliable over-current protection.

3. The LED panel shows the operation parameters and working status of the power supply; it has the function of fault self-diagnosis, which can remember the recent faults and improve the maintainability.

4. Functional units and components are all designed into modular structure, which can be expanded in series through components. It has small size, high efficiency, good reliability and maintainability.
