This is a toroidal (ring-type) transformer from Tianjin Grewin Technology Co., Ltd., available in 100VA and 200VA power ratings with dual primary windings for 12V or 24V output. The design features a low-hum, low-dispersion construction with a low level of magnetic induction. It supports horizontal, sunk, side, and bridge installation methods.
The transformer series includes models from 20VA to 6000VA, with specific dimensions and weights listed for each rating. For the 100VA model, the outer diameter is 85mm, height is 60mm, and weight is approximately 1.50kg. The 200VA model has an outer diameter of 110mm, height of 80mm, and weighs about 2.80kg. Standard no-load current for the 100VA is 30mA and for the 200VA is 100mA.
These transformers are used in audio equipment, communication systems, new energy applications, electrical control panels, and cable TV networks. They are sourced by manufacturers of electronic devices, power supply units, and industrial control systems. Tianjin Grewin's production facility includes over 50 toroidal winding machines and holds certifications such as CE, CQC, RoHS, UL, and ISO9000.

Before placing an order, confirm the exact electrical specifications for your application. Verify the required VA rating, primary and secondary voltages, and any need for additional taps or shielding. Request a detailed datasheet or test report from Tianjin Grewin Technology to ensure the transformer's performance parameters, such as regulation and temperature rise, meet your system's requirements.
Clarify all logistics and trade terms. Discuss the MOQ, which is not stated in the listing, and confirm packaging methods to protect the transformers during shipping. Inquire about available trade terms (e.g., FOB Tianjin) and payment options. Since the supplier's platform response rate is low, establish direct email or phone contact to negotiate terms and timelines effectively.
Implement quality verification upon receipt. Check the transformers for physical damage, correct labeling, and winding integrity. Perform basic electrical tests, such as measuring no-load current and checking for short circuits between windings and the core. For bulk orders, consider a third-party inspection at the factory before shipment to verify compliance with your agreed specifications and certifications.
