400XAC Series Programmable 1 Phase/3 Phase AC Power Source

One Power Workstation, Three Power Transmission

The 400XAC series is a single workstation capable of independently outputting single-phase, tri-phase, and DC power. The new External Trigger technology features synchronize waveforms for conducting effortless analysis. Free from the limitations of a single power system mode, the 400XAC series is suitable for any power source system used in laboratories and R&D departments.

Programmable Output Switching

The 400XAC series delivers programmable 1Φ/3Φ/DC output power in a single unit.

Synchronous Signal Capture

Synchronic signal output (ON/OFF/EVENT/External Trigger) functionality provides a useful tool for external monitoring, triggering use, and power analysis.

High Loading Capacity

The 400XAC series supports withstand inrush current up to four times the rated current, making it suitable for any high-inrush current loads (e.g., motors and compressors).

Customizable Output Waveform for Various Simulations

Adjustable starting and ending angle of the output waveform to simulates any operational circumstances.

Power of OCF

EEC proprietary Over Current Fold (OCF) function automatically adjust voltages, maintaining current for activating the DUT.

Design With Energy Saving

The built-in active power factor correction (PF>0.97) allows efficient conversion of electrical power into productive output, consuming less power for additional energy savings.
