Epoxy encapsulation and molded-in terminals provide moisture resistance, vibration durability, and simpler field wiring, reducing installation time and fault rates in harsh environments. This translates to lower maintenance needs and extended service life for automation panels where uptime directly impacts productivity. Copper windings paired with silicon steel laminations minimize copper losses and core losses, improving overall efficiency and reducing heat generation in operation, which supports cooler running transformers in switchgear enclosures. The dual primary 120/240 V and fixed 24 V secondary configuration simplifies integration into existing electrical schemes, avoiding tap adjustments and ensuring consistent control power for PLCs, relays, and contactor coils. A 350 VA rating supports multiple control loads from a single unit, reducing footprint and capital cost while simplifying spare parts planning. With 50/60 Hz operation, a 55°C temperature rating, and a 130°C insulation system, the design tolerates elevated ambient temperatures typical of factory floors, delivering reliable performance in demanding industrial spaces. RoHS compliance and UL Listed/CSA/cUL certifications provide regulatory assurance for panel builds and end-user installations, streamlining procurement and compliance workflows. The molded-in terminals and epoxy encapsulation also contribute to improved vibration resistance and dependable performance under shock and tilt scenarios common in manufacturing plants.

FAQs
For proper mounting, position the transformer in a ventilated panel area to manage heat build-up, and use the molded-in terminals for secure field wiring. The unit weighs about 11.2 lb, so plan for stable mounting on a panel rail or surface. Ensure clearance for maintenance and avoid direct exposure to moisture or corrosive environments.
The C0350E1B features a dual primary of 120/240 V and a fixed secondary of 24 V, rated at 350 VA. It uses copper windings and operates at 50/60 Hz with a 55°C temperature rating and a 130°C insulation system, making it suitable for standard industrial control loads and PLC peripherals.
Yes. The transformer is UL Listed, CSA Certified, and cUL Certified, with RoHS compliance. This combination provides regulatory confidence for North American installations, simplifying compliance documentation and supplier approvals for panel assemblies, OEM equipment, and repair/replacement programs.
Epoxy encapsulation protects windings and core from moisture and contaminants, reducing maintenance needs. Molded-in terminals minimize wiring wear from vibration. With proper enclosure protection and torque on terminals, expect extended life in factory environments, lower incidence of insulation failures, and fewer field service calls compared to non-encapsulated designs.
Applications with multiple 24V control loads—such as PLC coils, relay banks, valve actuators, and small motor contactor circuits—benefit from the 350 VA rating. This allows a single transformer to power several control devices, reducing footprint, wiring complexity, and overall cost in automation panels and machine control cabinets.
