Feature:

High-speed digital controlling processor is adopted as the output core of the tester. 32 bit double precision arithmetic is employed in the software, through which arbitrary high-accuracy waveforms of each phase can be produced. Since integrative structure is adopted,the structure of the tester is layed compactly.

Due to high density of fitting ponit, fidelity of waveform is high and harmonic component is small, which don’t have a strict requirement on the low-pass filter.

Digital Input and output

This tester has 10 channels digital input and 8 channels output.

The switching input circuit is compatible for both the empty contacts and 0-250V electric potential contacts in the input and output circuit. When the electric potential contacts are selected, 0-6V belongs to closed switch and 11-250V belongs to open switch.

Auxiliary DC Power Supply Output for Special Use

A circuit of special adjustable DC power supply output is allocated on the rear panel, which has 110V and 220V two shifts that can be used as test standby power supply on the spot.
