VARIABLE FREQUENCY POWER SOURCE
EPPS Series
Features of IGBT / PWM Variable frequency power supply:
1. Input voltage: 3-phase 380V input frequency: 50Hz, 60Hz.
2. Output voltage: 0 ~ 520VAC adjustable output frequency: 40-499.9Hz programmable finger setting.
3. Provide standard voltage, frequency, simulation test of various electrical products in the world.
4. Voltage, frequency, current and power meter are displayed by 4-digit led, which is simple, easy to read and high resolution.
5. Voltage (V), frequency (Hz), current (a), power (W), power factor number (PF) windows are measured and displayed at the same time.
6. No radiation interference, small harmonic component, and special treatment, no interference, pure and stable sine wave output.
7. Strong overload capacity, able to withstand 300% of rated current in an instant, with over-current, over high temperature, short circuit, instantaneous power-off protection and warning device.
8. Suitable for resistive, capacitive, inductive and other hybrid loads.
9. The inverter adopts star type mode, each phase can be loaded independently, which is suitable for three-phase completely unbalanced load.
10. Accept customized output voltage 0-1000v adjustable, output frequency 5-1000hz adjustable (can be connected to PLC, optional RS232 and RS485)
