Buy & Import Grewin Toroidal Waterproof Transformer With IEC from Tianjin Grewin Technology Co., Ltd. - China Wholesale Supply

The Grewin Toroidal Waterproof Transformer With IEC is a double-insulated, Class II transformer designed for outdoor and humid environments, meeting the IEC 61558-2-6:09 standard for short-circuit-proof safety isolating transformers. It operates with input voltages of AC 220V, 230V, or 110V and provides output voltages of AC 12V or 24V, with a power range spanning 105VA to 1KVA. The unit features electrostatic and magnetic shielding, temperature protection via a thermal switch, and overcurrent protection, ensuring reliable performance in demanding applications.

Constructed with a cold-rolling directional silicon steel annular core, the transformer uses Mylar for insulation protection and polyester 7C for core insulation. Primary and secondary windings are made from enamelled copper wire, while the terminal cannula and underlay utilise PVC and polyester 19C, respectively. The body is composed of PP+GFRP, and the unit is potted with resin for additional waterproofing. Typical industry standards for such transformers include insulation resistance of 500V DC at 100 MΩ minimum and a hi-pot test of AC 3.8kV for 5 seconds with a maximum leakage current of 5mA.

This transformer is suited for applications such as garden lights, LED underwater lamps, LED ground lights, outdoor power supplies, audio sound fields, stage lighting, and Christmas lights. Its waterproof design and compliance with international safety standards make it ideal for humid or outdoor environments. Buyers should confirm compatibility with their specific voltage and power requirements, as well as any additional certifications needed for their region.

Sourcing Grewin Toroidal Waterproof Transformer With IEC from Tianjin Grewin Technology Co., Ltd. - China Import Guide

Before placing an order, verify that the transformer’s input and output voltage specifications match your system requirements. Confirm the power range (105VA to 1KVA) is adequate for your application, as under-sizing can lead to overheating while oversizing may result in unnecessary costs. Additionally, check that the transformer’s certifications (IEC, VDE, UL, CE, ISO 9000) align with the regulatory standards of your target market to avoid compliance issues upon import.

Discuss logistics details with Tianjin Grewin Technology Co., Ltd., including lead times, which can vary depending on order volume and customisation needs. Clarify Incoterms such as FOB, CIF, or DDP to determine responsibility for shipping costs, insurance, and customs clearance. Payment terms should also be agreed upon in advance, with options typically including T/T (Telegraphic Transfer) or L/C (Letter of Credit), depending on the supplier’s policies and your risk tolerance.

Request a pre-shipment inspection to confirm the transformer meets the specified technical parameters, including insulation resistance, hi-pot test results, and temperature rise limits. Ensure the supplier provides a detailed test report and certificate of compliance with IEC 61558-2-6:09. Upon receipt, perform a visual inspection for any physical damage and verify the packaging is adequate for international shipping to prevent transit-related issues.
