Buck-boost design delivers 0.75 kVA at 60 Hz in a single-phase package. This stabilizes voltage in panels facing fluctuations, reducing nuisance trips and downtime. Suitable for control panels, PLC power rails, and motor starters in automation buildouts. Encapsulated EP enclosure with aluminum windings and a NEMA 3R rating provides rugged, indoor-outdoor performance. This construction protects critical electronics from dust, moisture, and incidental exposure, enabling reliable operation in weathering environments and simplifying outdoor panel deployments. Wiring is configured for 3D connections with no tap changes, which streamlines installation and minimizes wiring errors during commissioning. The result is faster, error-free panel builds and easier field service. A 115 °C rise rating supports operation in hotter environments without derating, improving uptime in hot plants and machine rooms. Primary voltage options of 240 V and 480 V with a 24/48 V secondary give flexible compatibility for varied control circuits, reducing inventory and simplifying engineering. The UL Listed certification further reinforces safety and compliance, while the NEMA 3R enclosure and indoor-outdoor capability support versatile deployment across facilities. These features translate into measurable savings in maintenance, downtime, and total cost of ownership for panel builders and end users.
