Hammond Electronics, Inc. Isolation Transformer, 10A, 1.2Kva, 120V; Chassis Mount Transformer Type Hammond CV1201200

The Isolation Transformer, 10A, 1.2KVA, 120V, is a chassis mount transformer designed for constant voltage regulation. It operates with an input voltage range of 120VAC (+10% to -25%) and provides a stable output of 120VAC (+/- 3%). This transformer features a ferroresonant design that protects against brownouts, overvoltage conditions, and filters out surges, line harmonics, and RF noise. It has a total harmonic distortion (THD) of 3% and includes a second stage of high-frequency filtering. The unit is equipped with a standard 3-wire grounded plug and receptacle, and it comes with a 15-foot heavy-duty cord suitable for extreme temperature ranges. The transformer is housed in a rugged two-piece ventilated steel enclosure and is intended for indoor use only. Notably, the transformer provides complete isolation from the source voltage, ensuring that the neutral output wire has no connection to ground, which is a UL requirement for this type of device. It is important to note that these units produce audible noise due to their design and are not suitable for office environments. The product is UL listed and complies with safety standards.
