Three in and out HPA series frequency converter 10kva ~ 300kva

Frequency converter adopts VPWM high-frequency technology (pulse wave width modulation technology), uses high-power imported IGBT module design, input and output are fully isolated, with stable and adjustable frequency, voltage regulation and frequency, voltage, current, Power digital indication and other functions can simulate the power grids of various countries in the world.

    Product characteristics

  Output voltage: single voltage 0-330 v, three-phase 0-520v

  Output frequency: 40-4999.9hz programmable dial setting

  Voltage, frequency, current, power meter using 4-bit digital led display, convenient, easy to read, high resolution

  Voltage (V), frequency(HZ), current(A), capacity factor(W),power measurement at the same time, display, do not need to switch

  No radiation interference, including small harmonic components, and after special treatment, no interference.

  Pure, steady sinusoidal output

  Large capacity, small volume, light weight, high efficiency, mute device, high reliability.

  Strong overload capacity, instantaneous current can withstand 3 times the rated current.

  There are over-current, over-high temperature, short-circuit, instantaneous power failure protection and warning devices.

  Suitable for use in resistive, capacitive, inductive and other nonlinear loads.
