Universal measuring relays One device, many functions DOLD Our experience. Your safety.

VARIMETER PRO: The multifunctional measuring relay Function principle [i Selecting measuring functions Voltage Frequency Current cos phi Active power Reactive power Apparent Asymmetry Phase power (unbalance) sequence Complex processes in automation, process and industrial building systems, together with increasing demands in energy and environmental engineering require high operating reliability and permanent availability of the system. The universal measuring relays MK 9300N / MH 9300 of the VARIMETER PRO series monitor up to 9 different parameters simultaneously. Quite simply and without much...

Maximum output function for your application Precise monitoring and diagnosis in machines and plants has gained increasing significance over the past years. Mill drives Large drives such as grain or cement mills often still use slipring rotor motors. sliprin Solu Solution: Employing a frequency monitor to control the ram ramp-up. Adv Advantage: A soft start of the working equipment preserv the mechanical drive elements and prevents serves curr peaks in the feeding mains. current The early detection of impending failures and preventive maintenance prevent costly damages. The VARIMETER PRO is the...
