As the flagship high-capacity model in Shunhong’s pure copper series, the Shunhong (Copper) SHJY-3000VA (TN30001) is an ultra-heavy-duty step-down converter engineered to run high-draw American (110V) and Japanese (100V) kitchenware, commercial appliances, and precision workshop tools in 220V environments. Encased in a sleek, minimalist fire-resistant white housing, it delivers uncompromised 3000VA power while blending naturally into modern homes and commercial spaces.
Dual-Port Bilateral 110V & 100V Synchronous Output
Unlike ordinary single-voltage converters, the (copper)SHJY-500VA features two isolated circuits on opposing flanks. The left outlet supplies calibrated 110V for American appliances, while the right outlet delivers authentic 100V for Japanese electronics. Both run simultaneously with zero cross-interference, eliminating the clutter and cost of buying two separate boxes.
100% Pure Copper Toroidal Windings
Engineered with high-purity pure copper wire tightly wound on a grain-oriented cold-rolled toroidal silicon steel core. Pure copper delivers significantly lower electrical resistance and higher thermal conductivity than aluminum models, keeping full-load heat generation exceptionally low while preventing voltage collapse under fluctuating grid conditions.
One-Touch Rocker Activation & Visual LED
Equipped with an independent physical rocker switch and high-visibility status LED. Click once to initiate instant voltage conversion without waiting for preheating. Eliminates the need to repeatedly plug and unplug cords, avoiding socket arcing, cord strain, and accidental looseness.
Whisper-Quiet (<20dB) Dual-Sided Passive Convective Cooling
Dense convective ventilation slits on both sides generate a natural airflow chimney effect that rapidly dissipates core heat without noisy cooling fans. Sound levels are strictly below 20dB, ensuring uninterrupted sleep and tranquil study environments.
Flame-Retardant ABS+PC Casing & Molded Power Cable
Constructed from high-grade fire-retardant ABS+PC composite engineering plastic that resists high temperatures, physical impacts, and chemical aging. Accompanied by an integrated 1.2m molded power cord with a 0.5mm² flame-retardant pure copper core for robust connection integrity.
Factory-Grade Quality Control with 37-Year Lineage & Customization Support
Backed by Shunhong’s established transformer manufacturing heritage since 1987. Each unit undergoes strict voltage calibration, full-load thermal testing, and 8-fold safety validation. Compliant with CE, RoHS, FCC, and CQC standards, with full OEM/ODM plug and voltage customization support.

Compatible Devices & Applications
US 110V & Japanese 100V Heavy Kitchen Cookware,
Induction Hobs, Steam Ovens, Commercial Coffee Gear & Machinery
Recommended Continuous Load Under 2400W
|
|
The (copper)SHJY-3000VA delivers a 3000VA peak apparent power capacity. Under continuous cooking conditions (lasting over 30 minutes, such as boiling soup or roasting), the combined load must be maintained below 2400W (standard 80% continuous duty rating). When connecting high-heat induction woks or electric steam ovens, confirm that their continuous power rating does not exceed 2400W. | |
How to Use This Voltage Converter
Frequently Asked Questions About Voltage Converters
Why is 100% pure copper essential for a 3000VA heavy-duty voltage converter powering commercial kitchenware?
At high loads nearing 16A, aluminum windings suffer from high electrical resistance, resulting in severe heat buildup and noticeable voltage drop that can cause induction stoves or CNC spindles to error out. The pure copper shjy-3000va 220v to 110v 100v transformer uses thick pure copper coils with ultra-low resistance, ensuring cool operation, zero voltage sag, and rock-solid power output.
What is the precise continuous load limit for the (copper)SHJY-3000VA (SKU: TN30001)?
The continuous load rating is recommended under 2400W. While the nominal capacity is 3000VA, adhering to the 80% rule guarantees that core temperature rise remains within safe margins, extending the transformer’s service life for decades. The copper shjy-3000va step down voltage converter dual socket is engineered specifically for heavy cookware and light industrial machines.
Can I connect two heavy appliances simultaneously, such as a 1200W American electric skillet on 110V and a 1000W Japanese IH cooker on 100V?
Yes, absolutely. The (copper)SHJY-3000VA features bilateral dual sockets designed for this exact scenario. With a combined wattage of 2200W (1200W + 1000W), it sits comfortably beneath the 2400W continuous threshold. The dual outlet 3000va pure copper step down converter delivers independent power across both sockets without cross-interference.
Can the (copper)SHJY-3000VA power imported workshop machinery such as mini CNC routers, air compressors, or packaging tools?
Yes. Motor-driven inductive machinery requires a 30% or higher power buffer due to startup inrush current. For any 110V or 100V tool rated under 1800W, the 16a heavy duty pure copper 220v to 110v step down transformer provides the substantial current reserves necessary to absorb startup surges without stalling the motor.
