Import Gf101 Program-Controlled Single-Phase Standard — Buy in Bulk from Supplier in China

The Gf101 program‑controlled single‑phase standard is a programmable power source designed for laboratory and field testing. It delivers selectable AC voltages of 57.7 V, 100 V, 220 V, 380 V and 750 V, with automatic range switching, and provides current outputs from 0.1 A up to 100 A across eight preset steps. Phase angle can be set from 0° to 359.99°, frequency from 40 Hz to 65 Hz, and each phase is rated at 40 VA. The unit measures 420 mm × 320 mm × 155 mm and weighs 12 kg, meeting the physical envelope required for most bench‑top setups.

The device incorporates a 32‑bit MPU, DSP and FPGA core, enabling hardware PID control and fast response to load changes. A 320 × 240 LCD presents data in Chinese or English, and the system supports RS‑232 communication for PC integration. Such architecture is typical for precision programmable sources that aim for harmonic distortion below 0.1 % and a temperature drift of 8 ppm/°C, matching industry expectations for high‑stability test equipment.

Typical users include power‑distribution utilities, university research labs, meter‑manufacturing quality‑control units and equipment‑testing services. The Gf101 can be applied to voltage‑regulation studies, harmonic analysis, reactive‑power compensation testing and load‑control algorithm verification. Beijing Gfuve Electronics lists the product under an imported tier with a harbour‑level trust rating; buyers should request MOQ, lead‑time and payment terms directly, as these details are not disclosed in the public data.

Beijing Gfuve Electronics Co., Ltd. is based at 01117‑8 Fortune Street No.67 Chaoyang Rd, Beijing 100025, China. The company is classified as an imported‑tier supplier and carries a harbour‑level trust tier, indicating that it meets basic verification standards on the platform. Its response rate is recorded as 0 %, so prospective buyers should anticipate a need for proactive communication to obtain detailed quotations or technical documentation.

The supplier specialises in programmable electrical test equipment such as the Gf101 and GF102 series. The public listing does not provide specific certifications, production capacity or client references, therefore buyers are advised to ask the supplier for factory audit reports, CE or IEC conformity statements, and any relevant test reports before finalising a purchase.
