Product Description
EI190 4000VA Step Down Three Phase Transformer 220V to 120V UL Copper Winding
The CHIPSEN EI190110-220-15461 is a 4KVA (4000VA) low frequency step down transformer that converts a 220V 50/60Hz input into a 120V output, delivered through two independent 120V–4000VA output groups (terminals 3–4 and 5–6) so one unit can feed two separate 120V circuits or be linked for a single higher-current load. Built on an EI silicon steel laminated core with 100% copper windings and housed in a powder-coated steel enclosure with integrated mounting brackets, it is designed for continuous duty in industrial power conversion, imported 120V equipment, and machine-tool control power. The design carries UL file E339338.
Key Features
- 4KVA continuous rating — 220V input stepped down to 120V, rated 4000VA per output group
- Dual output terminals — 3–4 and 5–6 give flexible wiring for two loads or paralleled service
- Full copper winding — lower copper loss and cooler running temperature than CCA-wound alternatives
- EI laminated silicon steel core — low no-load loss, low audible hum, stable output under load swing
- 50/60Hz dual frequency — one model works on both European and North American grid frequencies
- UL recognized construction — file number E339338 marked on the nameplate
- Enclosed steel housing — removable front covers for terminal access, top brackets for wall or frame mounting
- OEM / ODM welcome — voltage, VA rating, terminal layout, enclosure colour and label can be customized

Frequently Asked Questions
Q1: Can the two 120V outputs be used at the same time?
Yes. Terminals 3–4 and 5–6 are separate 120V groups and can feed two loads independently, within the total rated capacity.
Q2: Can it be used as a step up transformer?
Yes, the unit can be reverse-connected to convert 120V up to 220V. Please confirm the application with our engineers before wiring.
Q3: Do you accept custom voltage and VA ratings?
Yes. Send us your input/output voltage, VA rating, frequency and terminal requirement, and we will quote a custom design.
Q4: Is a sample available?
Sample orders are accepted. Lead time and sample cost depend on whether the model is a standard or custom design.
Send us your voltage, capacity and quantity requirement and our engineering team will reply with a technical proposal and quotation.
