With a 120/240 V primary and a 24 V secondary, this transformer delivers dedicated control power to relays, PLC inputs, and motor starters, enabling reliable control circuits without oversizing equipment. The 300 VA rating translates to robust performance across typical automation loads, reducing the need for multiple smaller transformers. Core construction uses epoxy encapsulation and laminations of high-quality silicon steel to minimize core losses and improve efficiency, especially in 50/60 Hz environments. The result is lower energy waste and cooler operation, which can extend component life and cut maintenance costs. Molded-in terminals and copper windings simplify installation and improve durability in vibration-prone industrial settings. Copper windings provide better electrical conductivity and heat resistance, while molded terminals resist wear from frequent connections. Compact dimensions—approximately 4.56 in long, 4.5 in wide, and 4.22 in high—fit standard electrical enclosures without compromising accessibility. RoHS compliance along with UL Listed, CSA Certified, and cUL certifications ensure regulatory alignment and procurement across global plants. The epoxy encapsulation also guards against moisture and dust ingress, supporting long service life in harsh environments. Designed for panel builders and integrators, this MTE-style transformer offers 50/60 Hz compatibility and molded-in terminals for quick wiring and reduced installation time.
