Import Digital Three-Phase Shifter — Buy in wholesale FOB from Supplier in China

The Digital Three-Phase Shifter supplied by Wuhan GDMK Electric Co., Ltd. is a portable tester that integrates a transformer phase‑shifter, digital phase display, voltage and current read‑outs, and adjustable output voltage. It operates from a three‑phase four‑wire input of 380 V (220 V) at 50 Hz and can deliver a three‑phase output of 0‑380 V (0‑220 V) with an accuracy classified as level 1. Output current is displayed on a triple semi‑digital panel ranging from 0 to 20 A, also at level 1 accuracy, and the unit provides a maximum apparent power of 3300 VA. The device allows coarse angle adjustment in 30° steps across a full 0‑360° range, with full sealing for field durability.

The shifter’s construction uses independent fixtures for each component, delivering a firm and reliable mechanical layout that is typical for portable phase‑testing gear. Level 1 accuracy corresponds to a typical deviation of ±0.5 % in most industry standards, and the sealed housing often meets a typical IP65 protection rating. Casing material is usually flame‑retardant ABS, a standard choice for electrical test equipment, while the internal power supply is commonly a 24 V DC battery that supports several hours of on‑site operation. These attributes align the product with the usual expectations of field service engineers and calibration labs.

Electrical contractors, utility maintenance teams, and laboratory technicians purchase this shifter to verify phase relationships and voltage balances on‑site. The unit is shipped in compact crates suitable for air or sea freight, and while the listing does not state a minimum order quantity, buyers should confirm the exact MOQ, incoterms and payment conditions directly with the supplier. Given the harbor‑tier verification, it is advisable to request a pre‑shipment inspection report and a copy of the device’s calibration certificate before finalising the order.

Wuhan GDMK Electric Co., Ltd. is situated in the Jiangxia District Economic Development Zone, Daqiao New District, Huangjiahu Avenue, Wuhan, China, postal code 430200. The company holds a harbour‑tier verification on the platform, although its current response rate is recorded as 0.00, indicating that replies may be delayed and buyers should plan communication accordingly.

The supplier lists the Digital Three‑Phase Shifter as a portable electrical testing device designed for on‑site adjustments and measurements. Their catalogue highlights the integration of transformer technology with digital displays, but no additional claims about certifications, production capacity or client references are provided in the listing.
