1. Product Overview
DASN Low-Voltage Current Transformer Drawing on the successful development experience of the DAS series, HEYI launched a brand new member, the DASN series low-voltage current transformer. The product is designed to match modern molded case circuit breakers and also employs advanced electromagnetic induction technology and first-class materials to ensure excellent performance even in complicated working conditions. It covers a wide current range from 60A to 1600A and comes with transparent terminal covers for easier on-site observation and maintenance. By optimizing the design of the magnetic circuit and insulation structure, this product greatly improves measurement accuracy and stability and functions well in various low-voltage distribution scenarios.
2.1 Integrated design saves space and reduces cost;
The DASN series low-voltage current transformers adopt an innovative plate installation structure, and the dimensions of its structure can be precisely calculated to achieve perfect matching with mainstream MCCBs. This equipment is designed to be relatively compact in physical structure, saving more than 40% of installation space compared with traditional transformers. The modular design will also be very unique, which could shorten the installation time by over 50%. The wiring solution of this low-voltage current transformer is flexible, which could bring about effective reductions in cable loss and material costs for customers, thus creating huge economic benefits.
2.2 Electrical performance of DASN is excellent to ensure safety and reliability of the system.
The DASN series products have obtained several international standard certifications such as IEC60044-1, EN60044-1, VDE0414-44-1, GB1208-2006, etc. The product is made of high-quality silicon steel sheets and special insulation materials. With a withstand voltage of AC 3kV/1min, its rated thermal current is up to 60In, and the dynamic current reaches 2.5lth. Its shell with V0 level flame retardancy effectively prevents flame spread in extreme situations, and when overload occurs, the accuracy limit factor FS 5 guarantees accurate measurement. This low-voltage current transformer has a wide applicable temperature: from -10 ℃ to 50 ℃, which can adapt well to various harsh environmental conditions.
2.3 Different DASN models to suit various application needs
The product series, which ranges from DASN240 to DASN250, contains more than twenty kinds of commonly used ratios. It covers 60/5-200/5 for general purposes in the DASN240 series; the DASN248 series covers middle current for 250/5-630/5; while the DASN250 series is specially optimized for large current at 600/5-1600/5. The secondary output of the low-voltage current transformer supports both 5A and 1A industrial standards, which can flexibly match all kinds of metering instruments and protection devices in multiple fields with excellent performance.
