Single-phase 400HZ power supply (medium power)

Product Profile:

The 400Hz medium frequency power supply manufactured by our company is a 400Hz medium frequency static variable frequency power supply specially designed and manufactured for aviation and military electronic and electrical equipment by using our company's unique patent technology and high frequency power electronic switching technology. It can be used in military electronic equipment such as aircraft and airborne equipment, radar, navigation and other occasions requiring 400Hz medium frequency power supply. It is a unit type variable frequency power supply. Source replacement products. The voltage and frequency of the product can be adjusted in a range of <20%. It is suitable for three-phase balancing and any unbalanced load, and can also be used as a single-phase power supply. It can adapt to various types of loads such as resistance, capacitance, induction and various mixed loads.

Product characteristics:

1. SPWM chip is adopted, which has high control precision, good waveform quality and can adapt to various loads.

2. IPM high frequency static inverters, small size, light weight, low noise, high efficiency, little interference to the outside world

3. Microprocessor control, the output voltage and frequency can be adjusted on-line, and the operation and fault state can be seen at a glance.

4. Suitable for three-phase balanced load and arbitrary unbalanced load, also for single-phase power supply.

5. Operational display digital LED panel, flexible and convenient to use, so that you are more handy

6. Single use or 19'standard cabinet
