Type B Current Transformer
1. Full DC & AC Leakage Detection Compliance
Detects 6mA DC and 20/30mA AC residual currents — fully compliant with IEC 62752 and UL2231, making it ideal for EV charging safety.
2. Wide Operating Temperature – From -40°C to +105°C
Engineered for reliability in extreme environments, from freezing cold to high-heat industrial or outdoor conditions.
3. Fast Calibration & Built-in Self-Test Logic
Supports automated calibration (≥240ms) and self-test mode (≥60ms), with clear SCR output logic (DC 4.8V when fault detected), simplifying integration and diagnostics.
4. Low Power Consumption, High Precision
Consumes only 110mW, yet maintains accurate detection through calibration signal compensation — ideal for energy-conscious smart systems.
5. Clear Digital Output with Strong Drive Capability
SCR signal output delivers clear fault status (LOW 0V / HIGH 4.8V), with current drive capability up to 5mA, allowing direct interfacing with control systems.
6. Designed for Seamless Embedded Integration
Supports 5V ±0.25V supply, simple digital pin control logic, and standardized signal timing – making it plug-and-play friendly for most microcontrollers and safety modules.
