Product Specifications

Technical details and manufacturing context for Voltage Feedback Sensor

Definition

The Voltage Feedback Sensor is a component used in electrical equipment manufacturing, specifically designed for voltage control units. It continuously monitors the output voltage of a system, converts the electrical signal into a measurable form, and provides real-time feedback to the control circuitry. This feedback enables the control unit to maintain stable and accurate voltage regulation by comparing the measured voltage against a setpoint and initiating corrective actions when deviations occur.

The sensor operates by detecting voltage across a circuit, typically using resistive dividers, operational amplifiers, or specialized integrated circuits to scale the voltage to a safe measurement range. The scaled signal is then converted, often to a digital format via an analog-to-digital converter (ADC), and transmitted to the control logic for comparison. This allows for precise monitoring and adjustment.

Key specifications include an input voltage range of 9–36 V DC, an output signal of 0–10 V DC, and an accuracy of ±0.5% of full scale. The response time is ≤10 ms, ensuring fast feedback for real-time control. The sensor operates within a temperature range of -40 to 85 °C and can be stored at -40 to 105 °C. It features an insulation resistance of ≥100 MΩ at 500 V DC and a dielectric strength of 2.5 kV for 1 minute, both tested according to IEC 60255-5. The protection rating is IP54–IP65 per IEC 60529, and the housing material is PC/ABS with a UL 94 V-0 flame retardant rating. The sensor weighs ≤200 g and has dimensions of 80×40×25 mm (L×W×H).

Materials used include semiconductor (silicon), copper, epoxy resin, and ceramic substrate. These specifications are reference values; for specific applications, verify model-specific data and standards with the legal manufacturer or supplier.

Working Principle

The sensor detects voltage across a circuit using resistive dividers, operational amplifiers, or specialized ICs to scale the voltage to a safe measurement range. The scaled signal is then converted, often to a digital format via an ADC, and transmitted to the control logic. The control logic compares the measured voltage against a setpoint and initiates corrective actions if deviations are detected, enabling stable voltage regulation.

Frequently Asked Questions

What is the input voltage range of the Voltage Feedback Sensor?

The input voltage range is 9–36 V DC, as listed in the specifications. This range is suitable for various control systems, but you should verify the exact range for your specific model with the manufacturer.

What output signal does the sensor provide?

The sensor provides an output signal of 0–10 V DC, which is linearly proportional to the input voltage. This analog signal can be used by control circuitry for monitoring and feedback.

What is the accuracy of the sensor?

The accuracy is ±0.5% of full scale. This means the measured voltage can deviate by up to ±0.5% from the actual value, which is suitable for many industrial control applications.

What standards are referenced for insulation and dielectric strength?

The insulation resistance and dielectric strength are tested according to IEC 60255-5. The insulation resistance is ≥100 MΩ at 500 V DC, and the dielectric strength is 2.5 kV for 1 minute. These are reference values; always confirm compliance with the manufacturer.
