JBK Series Transformer
Product Overview
As an upgraded product of traditional control substation transformers, this series adopts German imported silicon steel sheets and cold-pressed terminal technology, and achieves performance breakthroughs through three core technologies:
Multi-scenario adaptation:
Covering all JBK standard/JBK3/JBK5 models, supporting 220V-24V and other multi-voltage conversions, meeting the differentiated power supply needs of CNC machine tools, medical equipment and other precision equipment
Energy efficiency optimization:
no-load loss is reduced by 18%-25% compared to traditional models, and the overload capacity reaches 2 times the rated current for 1 minute
Security Architecture:
The power frequency withstand voltage between windings is 2500V for 1 minute without breakdown
IP2LX protection level and alloy base plate integrated design
It complies with international standards such as VDE0550 and IEC204-1 and is suitable for harsh industrial environments with an altitude of ≤3000m and temperatures between -15°C and +40°C.
