Micro current transformers are used to proportionally transform AC current signals into lower level AC current or voltage signals.

This series of products is compact in size, high in accuracy, small in phase shift, and easy to apply. It can accurately transform and isolate current signals and is mainly used for current, power, and energy detection equipment or electrical measuring instruments; At the same time, some products can use special processes to achieve 10 or even 20 times the overcurrent requirements, which can be applied to power protection equipment.

This series of products mainly uses through-hole direct input or pin input for the primary level, and asymmetric PCB direct soldering mode output for the secondary level. Installation is convenient, fast, and error free. At the same time, the product is made of flame-retardant PBT material or flame-retardant ABS engineering plastic, with excellent insulation and flame-retardant properties, and a flame-retardant rating of UL 94-V0; The epoxy resin encapsulation process has excellent waterproof, moisture-proof, and heat dissipation performance, and can be used in harsh environments.

In terms of selecting miniature current transformers, products made of PoMo alloy materials can be chosen, which have extremely high conversion accuracy and minimal phase shift, but also have the highest cost price; Nano crystalline material products can also be used, which have the advantages of high precision and low phase shift, and have more competitive advantages in cost and price; If used in relay protection, silicon steel material products can be selected, which have good overload performance and sufficient accuracy.
