Block 230 V ac Toroidal Transformer Dual 12 V ac Outputs 20 VA RKD 20/2x12

Block RKD 20/2x12 Toroidal Transformer is engineered for demanding electrical and electronic environments, providing a primary voltage of 230 V ac with dual secondary outputs of 12 V ac each and a power rating of 20 VA. Its robust toroidal core and dual secondary windings allow for series or parallel connection or independent use, making it highly versatile for different applications.

This open toroid transformer offers a compact footprint with a diameter of 61 mm and height of 31 mm, significantly reducing weight to just 350 g compared to stacked lamination transformers, enhancing ease of handling and installation. The low radiated magnetic field and minimal core noise make it ideal for noise-sensitive industrial, laboratory, and manufacturing equipment.

The lead termination type aids straightforward wiring connections, and the unit comes supplied with a mounting kit to facilitate installation in industrial power supplies, test instrumentation, and HVAC systems. With a maximum operating temperature of 40°C, this transformer supports durable operation in challenging conditions.

Certified for quality and safety with EAC, UL, RoHS, and cURus approvals, this transformer ensures compliance with international standards. The device’s insulation class B enhances its durability and reliability for continuous industrial use.

Dual secondary winding provides two 12 V ac outputs for flexible connection options. Compact toroidal design minimizes size while reducing electromagnetic interference. High efficiency with low iron loss and minimal induced noise (hum).

Open toroid core construction and lead termination ensures ease of installation. Operating temperature up to 40°C supports stable performance in industrial environments. Supplied with mounting kit for secure and fast mounting on surfaces.

Complies with EAC, UL, RoHS, and cURus standards for quality and safety. Manufactured in Germany with high-quality materials and craftsmanship.
