Bronson HE-D Series
High-Power, High-Efficiency Step Down Converters (230 V → 110 V)
The Bronson HE-D Series Step Down Converter family delivers a truly mobile, high-capacity answer for professionals who need to run North-American-voltage equipment from European mains. Each model—rated at 3000 W, 4000 W, or 5000 W—reliably transforms 220/230 V input into a stable 110/120 V output, eliminating the guesswork and bulk often associated with traditional transformers. Four on-board US NEMA 5-15 outlets let you power multiple devices simultaneously, while a robust enclosure, carry handles and rubber feet keep the unit ready for life on the road, in the studio or on a trade-show floor. Because the HE-D Series is dedicated to step-down conversion only, every watt goes toward efficient 230 → 110 V operation—no bidirectional circuitry, no added loss.
Key Features
High Continuous Power – Choose 3000 W, 4000 W or 5000 W to match your load profile without oversizing.
Pure Step-Down Architecture (230 V → 110 V) – Optimised exclusively for equipment designed around U.S. voltage and frequency.
Quad NEMA Output Panel – Four built-in, breaker-protected outlets simplify multi-device setups; no extra power strip required.
Soft-Start Technology – Intelligent inrush-current limiting prevents tripped mains breakers and safeguards sensitive electronics.

Use Cases
The HE-D Series Step Down Converter is particularly useful for on-site events where multiple 110 V lights, audio systems, or tools must be powered simultaneously without an unwieldy setup. In workshops or small production studios, these converters streamline operations by allowing easy plug-and-play connections for US-based gear. Rental services also appreciate having a single, mobile solution to accommodate multiple 110 V items at once. The soft-start mechanism protects both the converter and the equipment, ensuring a longer lifespan and fewer interruptions during operation.
