Special features
Electrostatically shielded
The 25 kVA single-phase K-Factor nonlinear ventilated transformer delivers robust power for demanding automation loads, reducing harmonic distortion and improving panel reliability. The copper windings minimize copper loss, delivering lower operating temperatures and longer service life, which translates into reduced maintenance costs and fewer outages. With taps for +5% and -5% (plus +2.5% and -2.5% in multiple positions), it enables precise voltage regulation across supply fluctuations, ensuring sensitive controls stay within specification. The 60 Hz rated core and windings optimize performance in standard North American facilities, while the electrostatic shielding reduces EMI, enhancing communication between automation devices and PLCs. UL Listed and NEMA TP-1 compliant, plus DOE 2016 efficiency, provide regulatory assurance and energy savings that support sustainability reporting. The sizeable 25 kVA rating, 240/480 V primary to 120 V secondary, and copper windings enable straightforward installation in control panels and distribution enclosures, with a weight of about 703 lb and dimensions suitable for upright racks. Engineers appreciate compatibility with DOE efficiency standards and Eaton's rugged build for long-term reliability.
