DVL 250 Lem

Voltage transducer DVL 250 V = 250 V PN For the electronic measurement of voltage: DC, AC, pulsed..., with galvanic separation between the primary and the secondary circuit. Features Applications Bipolar and insulated measurement up to 375 V Single or three phase inverters Current output Propulsion and braking choppers Input and output connections with M5 threaded studs Propulsion converters Compatible with AV 100 family. Auxiliary converters High power drives Advantages Substations. Low consumption and low losses Standards Compact design EN 50155: 2007 Good behavior under common mode variations EN 50178: 1997 Excellent accuracy (offset, sensitivity, linearity) EN 50124-1: 2001 Good response time EN 50121-3-2: 2006. Low temperature drift High immunity to external interferences. Application Domain Traction (fixed and onboard) Industrial.
