APM SPST300VAC4500W-2-9 - Linked 3-Phase AC Power Supply System
It 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. It 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.
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.
High Output Current Factor
The surge current could reach 5-6 times of the rated current, especially suitable for inrush current testing.
Output Simulation Sequence and Disturbance Simulation
Capable of simulating power line disturbance simulation test.
Built-in IEC Standard Test
