Description:

The Vinyas Microsystems “SMART DPM” is a microcontroller based, versatile microcontroller based instrument with variety of input configurations, display sizes and colour options . These 3 ½ 4 ½ and 5 ½ digit precision DPMs are ideally suited for OEM applications. The DPM models with different input configurations can accept signals from a wide range of sensors for the measurement of physical parameters like voltage, current ( both A/C or DC), load, temperature, pressure etc. The basic unit is powered by 5 volt DC. Other powering options like unregulated 6V, 8V, 12V, 24V DC are also available.
