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.

Enclosed Control Transformers

Enclosed control transformers from Hammond Power Solutions package the core and coil inside a protective metal enclosure that is ready to mount. This style is ideal when the transformer will be exposed in a mechanical room, on a wall, or in a location where people may come into contact with equipment. The enclosure provides electrical isolation and physical protection which simplifies code compliance for commercial, institutional, and light industrial installations.

Enclosed Control Transformers Key Features

• Factory assembled metal enclosure that protects live parts from accidental contact.
• Clean appearance and simple mounting for mechanical rooms, corridors, and equipment areas.
• Designed for light duty and general purpose control loads such as HVAC control circuits and lighting control.
• Suitable for applications that require circuit isolation between line and control wiring.
• Knockouts or wiring openings that make field installation straightforward for electricians.
• Secondary fuse provisions on many models for convenient overcurrent protection near the load.
• Reduces panel building time because no separate enclosure or guarding is required.
• Good choice where transformers must be accessible for inspection yet remain safely guarded.
• Available with common primary and secondary voltages that match building and equipment standards.
• Supports both new construction and retrofit projects where space for additional panel equipment is limited.

Enclosed Control Transformers Ratings and Certifications

• VA ratings tailored for general purpose and light industrial control loads.
• Enclosure styles that meet typical NEMA or equivalent protection expectations for indoor locations.
• UL and cUL listed models suitable for field installation in commercial and industrial buildings.
• CSA and CE compliance where applicable for broader market acceptance.
• RoHS compliant design that aligns with modern environmental standards.
