VL-CBR-5013A

VL-CBR-5013A Application Field and Working Principle

The VL-CBR-5013A is an industrial-grade, stand-alone, two-stage power monitor specifically designed for industrial and energy management applications. Suitable for both indoor and outdoor uses, this device features loop-powered accuracy and adjustable current/voltage inputs with accuracy of currents ranging from 5mA to 5A.

This device can be used in a variety of applications, such as motor control applications, power monitoring in industrial plants, monitoring of high-power HVAC systems, data acquisition and logging in industrial processes, and other applications that require precise current and voltage measurements.

VL-CBR-5013A Working Principle

At its core, the VL-CBR-5013A is a small, self-contained monitor that uses a combination of analog and digital techniques to measure current, voltage, phase shift, and power. The monitor can be programmed for any type of power measurement including peak, peak-to-peak, average, RMS, apparent, and reactive.

The VL-CBR-5013A has a two-stage power monitor that includes a current sense circuit and a voltage sense circuit. The current sense circuit is an operational amplifier configured to provide high input impedance, while the voltage sense circuit is a resistor bridge configuration that provides excellent linearity and accuracy. The voltage sense is connected to the current sense circuit and is used to determine the phase shift of the current sense output.

The two-stage power monitor then uses a Digital Signal Processing (DSP) technique to analyze the amplitude of the signals and to convert the voltage and current measurements into power reads. The power reads are then sent to the analog outputs or to a serial port

Conclusion

The VL-CBR-5013A industrial-grade two-stage power monitor is an ideal solution for power monitoring in industrial and energy management applications. It is accurate in both current and voltage measurements, and provides precise power readings. Additionally, the digital signal processing technique provides additional functionality and reliability.
