Selling Policy 25-000 - Distribution and Control Products and Services
The transformer uses copper windings and a dry-type construction to deliver durable performance with high efficiency, reducing heat under load and supporting longer service life. This translates to lower energy losses and a smaller footprint in compact electrical rooms, enabling easier deployment in new or retrofit projects. With 2 taps at +2.5% and 4 taps at -2.5%, it adapts to voltage swings common in PV farms and industrial facilities, helping maintain regulated secondary voltage and protecting sensitive equipment. Its NEMA TP-1 efficiency and UL Listed certification provide regulatory confidence, while the 80 °C rise rating ensures operation in hotter environments typical of busy switchgear rooms. Electrostatic shielding minimizes EMI, improving control-sensor accuracy and reducing interference in nearby automation equipment. Center-coil thermal indicators support proactive maintenance by signaling overheating before failures occur.
