1.5 HP Type 3HD ADD-A-PHASE Power Converter

The Add-A-Phase^® Type HD is a heavy-duty static phase converter engineered to provide balanced and efficient three phase power from a single phase source. Designed for demanding industrial and agricultural applications, the Type HD is ideal for high-load machinery, pumps, compressors, and other motor-driven equipment that require many starts per hour (60 or more).

With its advanced auto-transformer and capacitor-based design, the Add-A-Phase Type HD ensures excellent voltage balance across all three phases, maximizing motor performance and efficiency. Unlike traditional rotary converters, this static converter offers a compact, low-maintenance solution that delivers smooth power conversion without excessive energy loss or heat buildup.

Built to withstand harsh operating conditions, the Type HD features a durable, NEMA-rated enclosure for protection against dust, moisture, and extreme temperatures. Its rugged construction and high-quality components make it a long-lasting and dependable power solution for critical use applications where three phase utility service is unavailable or cost-prohibitive. Examples of critical use may include; Fire sirens, community warning sirens, flood gates, door openers, ice makers, and valve actuator pipeline motors.

Installation is straightforward, with no need for motor modifications or complex wiring. The Add-A-Phase Type HD seamlessly integrates into existing electrical systems, allowing businesses to power heavy-duty three phase equipment with minimal downtime and investment. Its ability to handle high-inertia loads and fluctuating power demands makes it an excellent choice for applications requiring consistent and reliable operation.

For industries that depend on robust and efficient power conversion, the Add-A-Phase Type HD delivers the performance, durability, and cost-effectiveness needed to keep operations running smoothly.
