M814 Introduction

The MultiPanel is a low cost three phase digital meter in a standard DIN 96 x 96 mm case, measuring the basic electrical parameters.
The standard unit can be used on any wiring system and any voltage between 10V to 415V LN (17V to 720V LL)
The MultiPanel is simple to use and is an ideal replacement for analogue meters.
