Use this multifunctional panel meter from RS PRO as a system controller for three-phase industrial equipment. It allows for the prompt detection of any electrical problems such as voltage imbalances and dropped lines to improve the efficiency and reliability of machinery. It's well suited to regulating and controlling the operation of industrial boilers, lighting and air-handling units.
The three-line unit offers selectable parameters which can be displayed at the same time to reduce the need for additional control panels. Its wide range of optional parameters includes frequency and AC current and voltage monitoring for enhanced versatility in use. The meter's LED (light-emitting diode) display is bright and easy to read, even in the dark.
Choose a panel meter like this for harsh environmental conditions. Its Ingress Protection (IP) rating of IP50 means it has good resistance to dust so it's safe to use where air contaminants are present.
