Hall DC leakage current sensors can be used to measure DC, AC, pulse, and various irregular waveform currents in photovoltaic inverters under electrical isolation conditions. The transformed signal can be directly collected and received by various acquisition devices such as AD, DSP, PLC, secondary instruments, etc. It is widely used in current monitoring and battery applications, inverter power and solar power management systems, DC screens and DC motor drives, electroplating, welding applications, frequency converters, UPS servo control and other system current signal collection and feedback control.

The AHLC-EA series adopts the principles of modulation and demodulation, zero magnetic flux, and electrical isolation perforation measurement for DC leakage current. It has good accuracy, linearity, and stability, and adopts UL94-V0 standard insulation shell.

Applied to various industries such as battery power supply, uninterruptible power supply (UPS), inverter power supply, switch mode power supply, etc.

The BA series products apply the principle of electromagnetic induction to measure the AC current in the power grid in real time. They use precision constant current technology and linear temperature compensation technology to isolate and transform it into a standard DC signal output. Powered by 24V or 12V safe voltage, it has the characteristics of strong overload capacity, high precision, high isolation, high safety, and low power consumption, and can be widely used in the field of industrial automation.

The residual current sensor in the BA series is used for leakage monitoring, monitoring the insulation status of electrical circuits or equipment, and avoiding accidents caused by reduced insulation performance of electrical circuits or equipment.

The product complies with GB/T 13850-1998 and GB 1208-2006
