Voltage relay with spring clamp - Voltage monitoring relay 9,6...150V VME421H-D-1 – Bender – B73010003: Voltage relay with spring clamp VME421H-D-1 Design of the electrical connection Spring-loaded connection, 1-phase undervoltage possible, 3-phase undervoltage possible, 1-phase overvoltage possible, 3-phase overvoltage possible, 1-phase window possible, 3-phase window possible, contains DC voltage undervoltage function, contains DC voltage overvoltage function, contains DC voltage window function, voltage measuring range 1 9.6 ... 150V, voltage type of the measuring range AC/DC, rated control supply voltage Us at AC 50 Hz 9, 6 ... 150V, Rated control supply voltage Us at AC 60 Hz 9.6 ... 150V, Rated control supply voltage Us at DC 9.6 ... 150V, Type of voltage for actuation AC/DC, Min. adjustable response delay time 0s, Max. permissible response delay time 0s , Min. adjustable off-delay time 0s, Max. permissible off-delay time 0s, Number of NC contacts 0, Number of NO contacts 0, Number of changeover contacts 2, Width 36mm , Height 90mm, Depth 110mm, The VME421H series voltage relays monitor frequency, undervoltage, overvoltage and the voltage between two threshold values (window function) in AC and DC systems. The voltages are measured as effective values. The current measured value is permanently shown on the LC display. The measured value that causes the alarm relay to switch is stored. System-specific properties can be taken into account using adjustable delay times, e.g. B. device-related start-up phases, short-term voltage changes, etc. The VME421H version takes the supply voltage from the system to be monitored and has an internal energy store
