카테고리: AC 전원 공급 장치 시리즈

제품 특징

The output frequency ranges from 500 Hz to 900 Hz with a wide adjustable range, and the frequency step size is 0.1 Hz.
The output line voltage adjustment range is specified by the user, with a voltage adjustment resolution of 0.1 V.
Chinese-language LED display with user-friendly operation.
The input power supply is single-phase 220 V; the cable length is 3 meters, and it is connected via a three-prong socket.
Power supplies are available in various configurations—including portable chassis-style, cabinet-style, and cart-style options—to suit different user needs.
