China supplier mini current transformer 40A/20mA ac current transducer
Feature:
1.Permalloy core, 2.High precision, good linearity; 3.Epoxy potting , Safe and reliable 4.Flame retardant (UL94- V0), 5.Environmental protection( EU RoHS). 6.Small size and light weight 7.Easy to assemble and weld Guideline: National standard gb 1208-2006; Industry Standard jbt 10665-2006. Use Temperature:-25℃-+85℃ Relative humidity:≤95% Scope of application: Suitable for instrumentation, etc., need to convert large current into small current for precise measurement, Used for precision measurement or as electrical safety protection. Notes: If the load connected to the secondary of the transformer exceeds the rated load capacity, it may result in reduced accuracy or saturation. If you need to increase the load capacity and we can provide customized.
Note: This schematic diagram is the basic working principle of the transformer. We can design the transformer sampling circuit for the customer.
