FAQs
Plan floor or wall mounting per the enclosure rating and weight. Ensure adequate clearance for cooling around the copper windings and allow space for connections and maintenance access. With a weight of 1144 lb, use proper anchors and lifting equipment to secure the unit and prevent movement during vibration or service.
Key metrics include a 75 kVA three-phase rating, 60 Hz frequency, 208 V primary input, and 208Y/120 V secondary output. The unit also provides a 50 dB sound level, 150 °C rise, copper windings, and voltage tap options (+2.5% and -2.5%) for regulation under supply fluctuations.
Yes. The transformer carries DOE 2016 Efficient compliance and UL Listed certification. These attributes help reduce energy costs in continuous operation, support safety compliance in industrial environments, and align with procurement standards that prioritize energy efficiency and safety.
The electrostatic shield and K13 rating minimize EMI and resonance between windings and nearby automation hardware such as PLCs and drives. This improves signal integrity, reduces nuisance trips, and enhances control loop reliability in harsh industrial environments, supporting higher uptime and safer operation of automated processes.
ROI varies with load profile and energy prices, but DOE 2016 efficiency reduces core and copper losses, yielding lower energy costs over the lifecycle. In high-harmonic environments, the K-Factor 13 design helps maintain efficiency and voltage regulation, contributing to longer equipment life and reduced maintenance expenses in drive-heavy plants.
