Hangzhi RIT series AC / DC Leakage Current Sensor
Hangzhi AC / DC Leakage Current Sensor, developed on the basis of Multi-Point Zero Flux Gate technology, is a measuring module that uses the principle of electromagnetic induction to convert the measured current into a DC/AC voltage (or DC/AC current) signal proportional to the primary current. The primary and secondary sides are highly insulated. It has the characteristics of high accuracy, high linearity, high integration, small size, simple structure, stable long-term work and adapting to various working environments.
RIT series leakage current transducer is designed for residual and micro current measurement from 0.01A to 10A, and output with voltage. It has been used for vacuum coating and data center power supply systems (Trusted by Vertiv Technology Co., Ltd).

Typical Applications of Hangzhi Leakage Current Transducer
• Measure instantaneous current and voltage values in isolation.
• Hangzhi Residual Current Transducer Products are available with range from 0.01A to 10A with non-contact method to measure current
• Highly flexible installation, and modular design to meet the different market demands of railway systems.
• Achieve high performance indicators (accuracy from 1% to 0.1%)
• Wide temperature range, high insulation withstand voltage and electromagnetic compatibility design to meet the railway standards of different countries.
The maximum allowable input leakage current of UPS products is up to 5% of the UPS rated load current, which is much higher than common 30mA configuration. Therefore, the operating current level must be increased when selecting the anti-leakage protector to prevent frequent misoperation. According to the regulations of the power department, UPS leakage protection It should be classified as a first-level general protection and belongs to leakage protection.
When there are multiple leakage protectors in the power distribution system, the selectivity of grading actions should be met. The rated leakage current of the upper-level leakage protector should be at least three times the rated leakage current of the lower-level leakage protector, and the minimum non-operation time of the upper-level leakage protector should be greater than the maximum cut-off time. The closing time of the lower level protector. Otherwise, due to the matching problem of the upper and lower actions, a large area power failure will occur.
Hangzhi residual current transducer products are designed to meet the requirements of multi-level residual current protections, with range from 0.01A to 10A, high accuracy & linearity, low zero offset voltage, high bandwidth and short dynamic response time.
