BWDK-S201F Dry-type transformer thermostatIt is an intelligent temperature controller researched and developed by Fuzhou Yingnuo Electronic Technology Co., Ltd. and is suitable for air-cooled dry-type power transformers. It utilizes the Pt100 platinum RTD embedded in the three-phase windings of the transformer to detect the temperature rise of the windings and automatically controls the temperature rise according to the temperature rise.Cooling FansThe start/stop, over-temperature alarm, and over-temperature trip to ensure the safe operation of the transformer.
