American Industrial Power Supply

In today's era of globalization and increasing industrial equipment exports, voltage standard differences have become a key factor restricting products from entering international markets. The US industrial power grid generally adopts a 480V three-phase power supply system, while many imported equipment or domestic Chinese equipment requires 380V voltage to operate. How to safely, efficiently, and compliantly complete voltage conversion has become a practical challenge for many enterprises. The 480V to 380V transformer with US UL certification launched by Shanghai Inshidan Electric Appliance Group Co., Ltd. is a high-quality solution tailored for this demand.

I. Core Product Advantages: Compliant, Efficient, and Reliable
1. US UL Certification, Direct Access to North American Markets

UL (Underwriters Laboratories) certification is one of the most authoritative safety certification standards in the United States and is also the "pass" for electrical equipment to enter the US market. Inshidan 480V to 380V transformers are strictly designed, selected, and manufactured according to UL standards, fully meeting the safety specifications of the US market in core indicators such as insulation performance, temperature rise control, short-circuit resistance, electrical clearance, and flame-retardant material usage, eliminating user concerns about equipment safety from the source and paving the way for products to smoothly enter the US market  .

2. Precise Voltage Conversion, Adapting to Multiple Scenarios
Input Voltage: Three-phase 480V±15% 60Hz, compatible with 460V power grid, frequency compatible with 50/60Hz
Output Voltage: Three-phase 380V (industrial main power), 208V (North American control/lighting), 30V/50V (safety control circuit)
Power Range: 1kVA–3000kVA, standard models in stock, non-standard customization cycle 7–15 days

This transformer is specifically designed to convert 480V voltage to 380V, meeting the power requirements of various industrial equipment such as machine tools, production lines, data centers, CNC equipment, and packaging machinery, ensuring stable operation of equipment in international markets  .

3. Electrical Isolation + Industrial-Grade Durability, Dual Protection
Electrical Isolation: Primary and secondary windings are completely isolated, effectively blocking grid harmonics and surge interference, creepage distance exceeds IEC standards by 20%, compatible with sensitive loads such as servo drives and precision instruments
Insulation Class: H-class (180°C) insulation, vacuum pressure impregnation process, high-permeability silicon steel sheets + oxygen-free copper wire windings, full diagonal lap joint stacking structure
Protection Rating: IP20–IP54 optional, stable operation from -20°C to 70°C, full-load temperature rise ≤90K
Dielectric Strength: Up to 2.5KV/60s, insulation resistance ≥100MΩ/DC500V
