Selling Policy 25-000 - Distribution and Control Products and Services
Harmonic mitigation design reduces total harmonic distortion, improving the reliability of sensitive loads and extending equipment life. This translates to lower cooling requirements and higher uptime in electrical rooms. Application: data centers, manufacturing lines, and healthcare facilities where clean power matters. The unit provides voltage regulation through taps at +2.5% and -2.5%, enabling stable operation during input fluctuations and reducing equipment stress across varying loads. Application: systems with variable demand, such as presses, furnaces, and motor drives. Copper windings and dry-type construction deliver high efficiency, durable performance, and lower maintenance costs. Application: new installations in tight spaces where thermal management is a concern. The rugged frame 918A and 200X wiring connection simplify mounting and field connections, speeding up retrofit projects. Application: retrofit in existing buildings with minimal downtime. Compliance and protection features include UL Listed and NEMA TP-1 approval, supported by an optional 80kA per phase SPD on the secondary, enhancing surge protection for critical loads. Application: data centers, hospitals, and control rooms requiring robust protection. Weather protection WS34 and electrostatic shielding further improve reliability in outdoor or challenging environments. Application: outdoor substations or harsh industrial spaces.

FAQs
Install in a suitable electrical room or enclosure, mounting using the 200X wiring connection for primary and secondary terminations. Set voltage taps to match system voltage variations (+2.5% or -2.5%). Install the secondary SPD as required and ensure UL Listed and NEMA TP-1 compliance are respected. Verify clearance for cooling and follow manufacturer installation guidelines to maximize thermal performance and longevity.
The transformer is designed to mitigate harmonics by its inherent dry-type copper-wound construction and engineering to reduce distortion in the 480 V system. This translates to lower THD, reduced overheating of downstream equipment, improved UPS and drive performance, and enhanced reliability for sensitive electronics in data centers, manufacturing lines, and medical facilities.
Yes. With UL Listed and NEMA TP-1 compliance, 150 kVA rating, 60 Hz operation, and a 0° phase shift, it provides clean power to sensitive loads. The +2.5% / -2.5% taps support voltage stability under varying load, while the 80kA per phase SPD option protects against surges common in data centers and high-demand manufacturing environments.
The unit is UL Listed and NEMA TP-1 compliant, reflecting adherence to recognized safety and efficiency standards for power distribution transformers. It also features electrostatic shielding and is designed for robust surge protection with an optional 80kA per phase SPD on the secondary, aligning with critical facility protection requirements.
Expect minimal routine maintenance typical of dry-type transformers, focusing on visual inspections and thermal monitoring. The copper windings and rugged frame support long service life, while harmonic mitigation reduces downstream equipment wear and energy waste, contributing to lower operating costs and improved uptime—key drivers of favorable ROI for data centers and manufacturing facilities.
