## Overview

The Vajravegha VVM303 is a cutting-edge Hall Effect based sensor module designed for precise, non-invasive DC voltage (up to 100V) and current (±50A) measurement. It features real-time energy tracking in Wh and Ah, serial UART communication with Modbus compatibility, and customizable over-current detection—ideal for industrial, solar, EV, and battery management systems. Made in India with robust electrical isolation and easy integration capabilities.

## Description

VVM303 Voltage Current Energy Sensor Module provides economical and precise voltage and current measurement solution for industrial and commercial applications. It allows system designers to monitor any current path without breaking or changing original system. Current flowing through the 9.0mm sensor slot will generate a magnetic field which is sensed and converted into a proportional voltage. The system uses precision resistors for DC voltage measurement and WCS1700 Hall Effect Sensor for current measurement. Diameter 9.0mm conductor through hole, Current Measurement Electrical Isolation 4000V Over current value can be easily set using potentiometer Bandwidth > 20kHz, nearly zero magnetic hysteresis Push button switch to toggle modes between DC Voltage Current, Watt hour and Ampere hour, over-current values and calibration setting Over Current can be detected by adjusting the preset RV1 for desired value of current.Zero Current Calibration Mode allows the user to reset the current reading to zero when there is no current flowing through the device. V, I, Wh and Ah values are available on Tx pin of Serial port Energy Wh and Ah values are auto saved Default Baud rate can be changed by sending character 'B' through the Serial pin. To maintain accuracy, use a good quality power supply with minimum voltage drift.  The device can be configured as a Modbus slave using a TTL to RS485 converter. Modbus Registers 40001 - 40008NOTE: Current measurement accuracy will be less for very low current values.

## Features

- Hall Effect based non-invasive current measurement, no shunt resistor or wire break required, based on WCS1700 sensor, precision voltage measurement
- DC voltage: 100V, DC current range: +/- 50A, Energy and Battery Capacity measurement in Wh and Ah with auto save
- Measured value can be fed to any micro-controller or Data Acquisition System,, Data is also available on Serial port, Default Baud Rate 9600, programmable,
- Current Measurement Sensitivity is 33mV/A, Voltage Measurement Sensitivity is 25mV/V, Diameter 9.0mm conductor through hole for current measurement, can be configured as Modbus Slave RTU via TTL RS485 Converter, Default Slave ID 1, programmable
- Typical Applications include Test and Measurement Systems, Instrumentation and Control Systems, Motor Control, Power Systems, Solar Systems, Battery Chargers, Electric Vehicles, battery capacity estimation, Load Detection, Over-Current Fault Detection, etc MADE IN INDIA.
