Overview

The SolaHD DT661H118S Drive Isolation Transformer is a high-capacity, industrial-grade solution designed for heavy-duty motor drive applications requiring robust power isolation. Rated at 118 kVA with a 460V delta primary and 230Y/133V secondary winding, this transformer ensures clean, stable power delivery for 100 HP drives operating on 60 Hz power grids. Its primary function is to isolate sensitive motor drives from upstream power sources, mitigating harmonic distortion, voltage spikes, and electrical noise that can degrade performance or damage equipment. Certified to multiple safety and performance standards—including UL 506, UL 1561, UL 25872, CSA C22.2 No.66, and cULus E7014—the DT661H118S meets stringent requirements for industrial environments. The transformer’s compact design and high-efficiency core minimize energy loss while maximizing reliability, making it ideal for installations where space is constrained but performance cannot be compromised. Applications span a wide range of industrial settings, including manufacturing plants, process control systems, conveyor belts, CNC machines, and utility power distribution networks. By providing galvanic isolation between the primary and secondary circuits, the DT661H118S protects downstream equipment from transient events and ensures consistent operation of variable frequency drives (VFDs) and other motor control systems. Its compatibility with standard 460V delta primary systems and 230Y/133V secondary outputs makes it a versatile choice for retrofitting existing installations or designing new power distribution architectures. Key benefits include extended equipment lifespan due to reduced electrical stress, improved power quality for sensitive electronics, and compliance with regulatory safety standards. The transformer’s UL/CSA listings validate its suitability for use in North American industrial facilities, where adherence to electrical codes is mandatory. With a focus on durability and low maintenance, the DT661H118S delivers long-term value while safeguarding critical industrial operations against power-related failures.
