Standing at the absolute apex of residential voltage conversion, the Shunhong SHJY-3000VA (N30004) is our flagship power transformer for Japan. Expertly calibrated to elevate Japan’s standard 100V grid power into stable, full-bandwidth dual 220V–240V outputs, this 3000W powerhouse effortlessly drives high-draw imported appliances—including induction cooktops, steam ovens, commercial espresso machines, and high-speed blenders.
Ultimate 3000VA Peak Power for Heavy Culinary Loads
Designed for high-demand cookware that trips smaller converters. The SHJY-3000VA provides tremendous power reserve, easily soaking up cold-start inductive surges and sustained heating cycles.
High-Purity Toroidal Silicon Steel Core
Precision-wound cold-rolled silicon steel toroidal core achieves >90% power conversion efficiency. Low internal magnetic leakage ensures silent operation (<35dB) and modest operating temperatures.
Bilateral Dual 220V Sockets for Dual Heavy Kitchen Equipment
Both left and right flanks feature high-amperage 220V universal sockets. The bilateral separation guarantees that two thick, rigid cords plug in securely without mechanical stress or pin bending.
1.5mm² Integrated Japanese Plug & Heavy-Duty Conductor
Factory-integrated 1.2m Japanese 2-prong cable built with 1.5mm² oxygen-free copper conductors. Tested to handle high continuous currents without wire jacket softening or voltage losses.
Nine-Fold Safety Network with Dual Thermal Cutoff Sensors
Dual internal thermal cut-off sensors monitor core and casing temperatures in real time, triggering instant disconnect upon overheating. Backed by UL94 V-0 flame-retardant housing and an auto-reset breaker.
38-Year Direct Factory Pedigree & Commercial Grade Reliability
Engineered and produced by Foshan Shunhong (since 1987) under strict ISO9001, CE, and RoHS standards. Fully approved for international baggage check-in without battery or chemical hazards.

Safety Buffer & Prohibitions The 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. Ensure the Japanese wall circuit breaker (typically 15A or 20A dedicated kitchen line) can support the corresponding input draw. | |
How to Use This Voltage Converter
Frequently Asked Questions About Voltage Converters
Q1: Can the Shunhong SHJY-3000VA safely power a 2100W Chinese induction cooker in a Japanese residence?
A: Yes. A 2100W induction cooker operates well within the SHJY-3000VA’s 2400W continuous threshold. The Shunhong SHJY-3000VA japan step up transformer features heavy-gauge cold-rolled toroidal windings that handle the continuous electromagnetic coil switching without tripping or overheating.
Q2: What is the precise continuous load limit for the SHJY-3000VA (N30004)?
A: The continuous load rating is strictly recommended under 2400W. While the apparent capacity is 3000VA, adhering to the 80% rule guarantees that core temperature rise remains within safe margins, extending the transformer’s service life for years. The SHJY-3000VA 100v to 220v voltage converter is engineered specifically for heavy kitchenware.
Q3: Can I connect two appliances simultaneously, such as a 1000W rice cooker and an 800W soup stewer?
A: Yes, absolutely. The SHJY-3000VA features bilateral dual 220V sockets designed for this exact scenario. With a combined wattage of 1800W, it sits comfortably beneath the 2400W continuous threshold. The dual outlet 3000va step up converter 100v 220v delivers independent power across both sockets.
Q4: How does the SHJY-3000VA manage heat dissipation during hours of stewing or baking?
A: The unit employs stereoscopic natural convective airflow with top and lateral ventilation grilles, augmented by dual smart thermal sensors that constantly monitor coil temperatures. Encased in fire-rated ABS+PC housing, the flagship 100v to 220v voltage transformer for kitchenware stays cool and silent without loud fans.
