TSR- three-phase dry-type isolation transformers
Three-phase dry-type isolation transformers of TS(З)R series are made with a protective separation of the primary and secondary windings. Meet the requirements of GOST IEC 61558-1, GOST IEC 61558-2-4. Transformers are manufactured according to TU 3411-001-88223587-2015 and are intended for the protective separation of the primary circuits of the transformer connected to the power source from the secondary circuits to which devices or other equipment are connected.Download the questionnaire on transformers Calculate price SEE SPECIFICATIONS
Isolation transformers are used where, according to the rules of electrical installations or the requirements of technical conditions for electrical appliances between the circuits, double or reinforced insulation is required.
Type of transformers based on moveability - stationary.
Mode of the transformers operation is continuous.
Type of installation - connected (designed to power specific devices or equipment, or parts thereof), built-in (designed to be embedded in a specific device or equipment, or into parts thereof, the shell of which provides protection against electric shock).
Connecting to the transformer is made through special, labeled in accordance with the scheme terminal clips.
Transformers allow long-term overload voltage of not more than 10%, while the transformer current should not exceed the rated current at the rated supply voltage.
