3000W Three Phase AC Source System

Product Introduction:

APM 3 Phase Ac source SPS300VAC3000W is capable of delivering 3000VA of output power.3 Phase Ac Power Source is a 3-phase output programmable AC Power Supply which provides with high power density. With high speed DSP+CPLD control, high frequency PWM technology, active PFC design, It is able to provide not only stable DC/AC output power, but also 3-phase / 1-phase output. This AC power supply is featured with high power density, high reliability and high precision, meanwhile it possesses operation interface of touch screen and keys manually. It is able to analog output normal or abnormal power input for electrical device to meet test requirements, which is applicable to electric, lighting, aviation sectors, etc. It could be applied to enterprise`s production test as well.


Product Features:

● Large touch color screen, possess complete functions and easy to operate

● AC+DC mixed or independent output mode for voltage DC offset simulation

● Capable of setting output slope/phase angle, 0~359.9°

● Output frequency 15~1000Hz, capable of setting output slope of voltage and frequency

● High output crest factor could satisfy surge tests requirements

● Multiple current measuring level selection. Increase measurement accuracy

● Standard USB data interface, support CSV file waveform import

● OCP/OVP/OPP/OTP/ Short circuit protection

● Built-in power meter, which is capable of measuring 15 electrical parameters per phase, including voltage, current, power, etc

● With reverse current protection to avoid current flowing backward

● Capable of setting voltage and current output restriction, support for constant current output mode



Basic Functions:

1. Adjustable Phase Angle/Slope

Adjustable Phase Angle/Slope is applicable to verification test of ON/OFF inrush current testing. This function is applicable to start inductive or capacitive load with large capacity to avoid high current when instantaneously start the device.

2.High Output Current Crest Factor

The surge current could reach 5-6 times of the rated current, especially suitable for inrush current testing.
3. Output Simulation Sequence and Disturbance Simulation

Capable of simulating power line disturbance simulation test.


Advanced Functions:

1.Built-in IEC Standard Test
Built-in IEC standard test could be recalled directly.

2.3-Phase Operation and Parallel Mode

Support 3-phase operation, 3 units in parallel
