PowerHome Launches New 3-Phase SCR Power Controller Series, 3-Wire & 4-Wire Models Available
PowerHome rolls out its brand-new three-phase SCR power controller lineup, including dedicated 3-wire and 4-wire variants. Designed for industrial 380V power regulation, the new series delivers precise voltage control for heating, automation and industrial cabinet applications, expanding the brand’s power control hardware portfolio for global manufacturers.
- (1888PressRelease) July 18, 2026 - PowerHome, a trusted supplier of professional industrial power regulation equipment, officially announces the launch of its brand-new three-phase SCR power controller series, covering two core models: the 3-wire SCR power controller and the 4-wire SCR power controller, to satisfy diverse industrial wiring and power supply requirements across worldwide manufacturing sectors.
For industrial facilities running on standard 380V three-phase power supplies, wiring structure differences have long created matching obstacles for power regulation devices. Traditional single-phase SCR controllers fail to meet high-load three-phase heating, furnace temperature control and energy storage cabinet power adjustment demands, while outdated three-phase regulators lack compatibility for both 3-wire and 4-wire circuit layouts. To resolve this industry pain point, PowerHome has developed two targeted three-phase SCR power controller solutions with fully optimized circuit logic and internal thyristor modules.
The 3-wire SCR power controller, accessible at https://www.powerhome.com/3-wire-scr-power-controller, is engineered for balanced three-phase load circuits widely used in industrial furnaces, large infrared heating equipment and metal processing production lines. It adopts compact integrated packaging with high-speed phase-shift triggering technology, which ensures stable output voltage adjustment without phase imbalance, greatly lowering the risk of component burnout under continuous heavy-duty operation. Built-in overcurrent, overheat and short-circuit protection circuits extend service life and reduce factory maintenance downtime for long-running industrial equipment.
Meanwhile, the all-new 4-wire SCR power controller (https://www.powerhome.com/4-wire-scr-power-controller) caters to unbalanced three-phase loads and equipment requiring neutral wire connection, such as multi-zone temperature control cabinets, packaging automation machinery and new energy auxiliary heating systems. The added neutral wire channel effectively eliminates voltage drift caused by uneven load distribution, supporting accurate fine-tuning of power output even when single-phase loads fluctuate drastically. Its standardized terminal layout enables fast on-site installation, compatible with most mainstream industrial control cabinets without extra wiring modification.
All units in the new three-phase SCR series retain PowerHome’s core advantages of low electromagnetic interference and wide power range coverage. Every product undergoes strict aging testing before delivery to guarantee consistent performance in harsh workshop environments, including high temperature, dust and frequent start-stop cycles. The release of these two three-phase controller models completes PowerHome’s full-spectrum SCR product matrix, combining single-phase, three-phase 3-wire and three-phase 4-wire options to deliver one-stop power control solutions for global system integrators, equipment manufacturers and industrial heating plant operators.
Company spokespersons stated that the new three-phase SCR power controller series has received early trial orders from automation manufacturers across multiple regions. PowerHome will continue upgrading its power regulator product lines, focusing on higher precision, energy-saving performance and cross-scenario compatibility to support sustainable and efficient industrial production worldwide.
