FAQs
For reliable installation, ensure adequate ventilation and clearance around the transformer for natural air cooling, given the 80°C rise rating. Plan for a secure mounting footprint of roughly 20.36 in by 22.87 in base and a height of 37.59 in. Verify rail or panel mounting compatibility and provision for primary 240/480 V feeds and secondary 120/240 V outputs.
The unit features a 240/480 V primary and a 120/240 V secondary. It includes multiple taps for voltage regulation: +5%, -5% (two taps), +2.5%, and -2.5% (four taps). Use taps to compensate for voltage drop along feeders or loading changes to maintain consistent downstream equipment performance.
KT-13 K-Factor nonlinear ventilation is designed to handle non-linear, harmonic-rich loads common in drives and automation equipment. It improves cooling efficiency by responding to load-driven heat, reducing thermal stress and extending transformer life, which helps protect sensitive electronics and maintain stable voltage in demanding applications.
Yes. The NT20P11B1516CU is described with DOE 2016 Efficient notes in its catalog data, indicating its design and operation align with energy-efficiency standards. This supports energy-management goals and can contribute to lower operating costs in facilities with high annual energy usage.
Key ROI drivers include copper windings and a robust 80°C rise rating that enable reliable operation under typical industrial loads, reducing maintenance frequency. Regular checks should include ventilations clearance, inspection of connections for tightness, and monitoring for unusual heat during peak loads to prevent downtime and extend service life.
