FAQs
The S38D11P02PX uses a rugged NEMA 3R enclosure designed for indoor-outdoor applications, providing reliable protection against dust, moisture, and weather exposure. Its 68P frame size aligns with standard mounting patterns, simplifying installation in outdoor cabinets or semi-exposed plant areas. With UL Listing and aluminum windings, it is a robust choice for panel builders seeking dependable outdoor performance.
This transformer is a single-phase device with a primary voltage of 380 V and a secondary voltage of 120/240 V. It includes four taps: 2 at +2.5% and 2 at -2.5% to allow voltage adjustment. Rated at 2 kVA and designed for 50–60 Hz operation, these taps help maintain precise output under fluctuating input conditions.
A 2 kVA rating supports typical control loads in compact panels, allowing you to minimize transformer count and reduce overall cabinet size. This rating helps maintain clean power delivery to relays and PLCs, potentially lowering wire runs and improving heat management. Aluminum windings contribute to weight savings and corrosion resistance, further improving installation efficiency.
The S38D11P02PX is UL Listed and housed in a NEMA 3R enclosure suitable for indoor-outdoor use. Its 50/60 Hz catalog notes ensure compatibility with common national grids, while the epoxy encapsulation and aluminum windings enhance durability. These certifications and features align with industry safety, reliability, and environmental requirements for panel builders and OEMs.
Plan for a standard 68P frame mounting position and ensure adequate clearance per the enclosure guidelines. Use the four taps for voltage tuning as needed, and route wiring to the Hold connection per the manufacturer’s specification. Expect a weight around 44 lb, and consider outdoor-rated placement for outdoor-use environments. Verify UL and NEMA 3R compliance before commissioning.
