FAQs
Ensure adequate clearance for 28.22 in width and 48.56 in height, confirm indoor mounting on a stable base, and verify 200X wiring connections. Check room ambient conditions to maintain the 115 °C rise rating without triggering excessive cooling loads. Plan for space for service clearance and future tap adjustments.
The harmonic mitigating design reduces input current distortion and voltage distortion, lowering the peak harmonic currents that stress downstream drives. This translates to lower heating, fewer nuisance tripping events, and longer life for connected motors and drives, while maintaining stable 208Y/120 V secondary outputs for sensitive controls.
Yes. It provides a three-phase 480 V primary with a 208Y/120 V secondary, supporting typical automation panels and control circuits. The fixed taps and copper windings offer reliable voltage regulation under dynamic load conditions common in automated assembly lines and robotics systems.
The unit is UL Listed and certified for NEMA TP-1 efficiency, with a NEMA 2 enclosure. These certifications assure safety, reliability, and energy efficiency for indoor industrial environments, aiding procurement decisions and regulatory compliance for plant operations.
Expect reduced maintenance due to improved power quality and lower thermal stress on downstream equipment, which can extend component life and reduce replacement costs. The UL TP-1 efficiency and compact, shielded design also contribute to lower energy waste and easier, faster commissioning, delivering measurable ROI over time.
