We have released the official FW 1.1.3 firmware update for the ShackMaster Power 600 power supply.

The main improvement of this release completely changes the approach to measuring input voltage and guarantees users maximum data accuracy.

The mathematical model for evaluating input current parameters has been completely redesigned:

1. Previous algorithm: The system used the Goertzel algorithm to calculate the Fast Root Mean Square value (Fast RMS).
2. New algorithm: The power supply has switched to full True RMS calculation.

Previously, due to the specifics of the Fast RMS calculations, the readings displayed on the device could have slight discrepancies compared with actual measurements. Now, thanks to True RMS, the integrated monitoring system of the ShackMaster Power 600 displays the input voltage with the accuracy of a professional laboratory multimeter (voltmeter).

The update is already available for download. The new firmware can be installed using the free ShackMaster control software on the ShackMaster Power 600 product page.
