  • Which kinds of the aluminum cover resistor are used by inverters？

    As we known, the Al-shell power resistors are used to brake for the inverter, so we can call them as braking resistors. To the system of high-inertance, the motor can produce current when reducing the speed. At the same time, the current can go to the inverter to rise the voltage of the inverter. When the [...]

  • What kinds of water-cooling resistors are made by YINGFA?

    The Water-cooling Resistor is a kind of high performance production, with serval engineers’ hard work in 2008.At present, there are more kind types of water-cooling resistors. Accroding to the test, the withstand voltage of the resistor is up to 5KV. Sometimes, we can product the resistors with high-voltage or high-current(10KA).
    The power  of the resistors is accroding to [...]

  • Temperature control switch for high power resistor

    YINGFA can add the temperature control swith to all kinds of the high-power resistors according to the requirements of customers.
    Usually, the temperature switch valse is 125℃/130℃/140℃, at the same time, we can setup according to the need of customer.

  • What is the ultra-thin Aluminum housed resistor used for?

    A：目前各行业大部分的公司产品都追求在满足各项性能的前提下尽量将产品小型化完美设计，以获得客户的亲睐。超薄铝壳电阻是颖发公司专业为变频器行业设计和生产的一款精小型铝壳电阻，它具有功率大，散热快，易安装等优点。由于它非常的薄，适合安装在柜子里面，这给变频器行业的客户带来了非常的方便和美观。
    Usually, the thin value of resistor is 5mm/7mm/8mm/15mm/20mm,and so on. We can make it according to the needs of customer.

  • How much is the highest power value of the trapezoidal aluminum-housed Resistor?

    The highest power value of the trapezoidal aluminum-housed resistor is 3KW/PCS. If the value is over 3KW, it can be produced to be RXLG-Resistor-Box, which contains sevaral RXLGs(trapezoidal aluminum-housed resistor)

  • How much is the highest power value?

    Answer: The highest power per high power resistor is 20KW. If the power is over 20KW, We have to produce it to be Resistor Box.
