Product Overview

With a maximum input voltage of 5000V AC and a standardized 0.333V AC output, the S Series Split Core Current Transformers ensure safety and compatibility across diverse power management platforms. The series maintains a strict ratio error of ±1% and a minimal phase error of less than 2′ at 50% rated current. Encased in UL 94-V0 rated flame-retardant ABS, these transformers operate reliably between -15°C and 50°C. Ideal for HVAC, smart lighting, and building automation, they meet UL and CE standards, providing manufacturers with a durable, high-accuracy solution for complex electronic systems and motor protection.
