App calculates voltage drop between LED drivers and fixtures
The Dr Voltz app can be used to calculate the voltage drop depending on the length of cable which links the LED lighting fixture and an LED driver, as well as a number of other critical installation factors.
Dr Voltz aims to simplify calculating the voltage drop for either constant voltage or constant current LED applications and assists in planning cable runs, cable specifications and LED system parameters to avoid potential onsite LED installation issues.
By downloading the free app from Google Play and entering a series of data values into the Standard Calculator, including the cable diameter, fixture voltage, distance from the fixture to the LED driver and the forward current of the LEDs, the app calculates a voltage drop value for a specific cable length. In addition, the user is also provided with a value at which the driver voltage should be set, in addition to a simple graph demonstrating voltage drop along the length of the cable.
Dr Voltz provides quick, accurate voltage drop calculations and an automatic warning when the LED forward current exceeds the rated cable forward current.The Advanced Calculator goes one step further and allows the user to determine the maximum LED forward voltage and number of LEDs within a remotely placed fixture, given an LED driver voltage and cable distance.
IST developed the app in order to facilitate installation designs for its iDrive centralised LED driver range and customer demand was so high for a simple app that the team released the free app for everyone to use.
The Dr Voltz app is free to download from Google play at and is compatible with Android version 4 and all subsequent software versions.
