Control transformers

Product catalog summary
Overview: The document details the LH series of control transformers by TrafoX, emphasizing their low losses and high quality. These transformers are manufactured by Muuntosähkö Oy - TrafoX, with operations in Finland, Estonia, and China, and are designed for various applications.
Specifications: The LH series features dual primary windings (230V and 400V) with an adjustable voltage setting of ±5%. They comply with DNV, Lloyds Register of Shipping, and Bureau Veritas standards for transformers under 250VA. The transformers are classified under T60/B temperature classification and use recyclable packaging materials.
Safety Features: Protective insulation around the coil, optional earthing of the iron core, and high-quality terminal blocks are included. Live conductors are protected against direct contact, and coil conductors are soldered to prevent breakage during installation.
Installation: Transformers up to 250VA support both DIN-rail and screw mounting, have a good power-to-weight ratio, clear terminal markings, and include a wiring diagram for quick installation. Individual packaging ensures cleanliness during storage and shipping.
Standards: The LH series complies with EN61558-2-6 and EN61558-2-4 standards and carries the CE mark, suitable for fixed mounting in cases or electrical switchgear installations.
Technical Data: Detailed specifications for various models include power ratings (40VA to 1000VA), primary and secondary winding voltages, frequency, protection class, isolation voltage, insulation class, ambient temperature range, and mounting options.
Measurements: Dimensions and weight for each model are specified to aid selection based on space and weight constraints.
Additional Overview: The document also covers transformers from the Trafox LH-series with power capacities from 1500VA to 5000VA, available in horizontal (XHM) and vertical (XHP) models.
Technical Specifications: Primary winding is 230/400V ±5%, with secondary options of 24V AC or 230V AC. Models range from 1500VA to 5000VA, with a frequency of 50/60Hz, protection class IP2X, isolation voltage of 4kV AC, and insulation class T60/B for 1500VA models, T40/B for others. Ambient temperature ranges from -20°C to +60°C for 1500VA models, -20°C to +40°C for others. Standards include EN61558-2-6 and EN61558-2-4, CE certified, with screw fastening installation.
Measurements: Specific dimensions and weight are detailed for each model, such as the XHP2000_24 model with dimensions of 210mm x 168mm x 261mm and a weight of 20kg.
Applications: Suitable for a wide range of applications, including control transformers and other electrical systems requiring reliable power conversion.
Manufacturer Information: Muuntosähkö Oy Trafox, based in Helsinki, Finland, specializes in the development and customization of transformers, chokes, filters, and monitoring devices.
