Introduction

USBisoVM is a unique data acquisition device that uses a standard USB port. Plug it into your RMS unit or into a Computer.

USBisoVM has six +/- 100 VDC electrically isolated voltmeters.

USBisoVM uses six 24 bit Delta Sigma ADC,s to deliver accurate DC voltage readings.

Board Overview

The USB isolated voltmeter board (USBisoVM) has 6 isolated voltmeters that transfer data back to a control module via USB. The USBisoVM is a monitoring device only, and requires either a PC,SBC, or RMS unit to communicate.

Each voltmeter is capable of measuring up to ±100 VDC with 24-bit accuracy. The data and power lines for each voltmeter are isolated with a chip-scale air core transformer. This enables each voltmeter to measure different DC voltage sources without any effect on the main board or other voltages.

This technology enables the ability to measure (but not limited to):

positive and negative voltages.
separate power sources.
individual batteries in a battery bank.
shunt voltages for equipment that may
be drawing or generating power.
solar panel voltage and amperage.
wind turbine voltage and amperage.
battery charger voltage and amperage.
