Hammond Power Solutions control transformers are designed to provide reliable low voltage power for control circuits in industrial machinery, motor control centers, HVAC systems, and automation panels. They are engineered to handle the high inrush current of contactors and solenoids while maintaining stable secondary voltage so that critical control devices operate safely and consistently. The product family is available in three main construction styles so you can match performance and protection level to your installation environment.
Use molded control transformers when you need maximum protection in harsh or contaminated areas. Choose open core control transformers when panel space and flexibility are most important. Select enclosed control transformers when you want a ready to install unit with integrated protection for commercial or light industrial locations.
Molded Control Transformers
Molded control transformers from Hammond Power Solutions are built for demanding industrial environments and high inrush control loads. The windings are completely encapsulated in resin which protects the core and coil from moisture, dust, oil mist, and vibration. This style is an excellent choice for heavy duty motor starters, machine tools, press lines, material handling equipment, and any application where uptime and durability are critical.
Molded Control Transformers Key Features
Encapsulated coil design that seals windings from dust, dirt, and moisture.
