NK VTR6-420-24L-DIN - AC Voltage Transducer, VTR Series Voltage Range = 600 V Output Type = 4-20 mA Supply Voltage = 24 V loop-powered Mounting = DIN rail compatible VTR Series AC Voltage Transducers are high-performance True RMS transducers for sensing voltage in single- and three-phase installations. Applicable on circuits of 120 V, 240 V, 480 V and 600 V, the VTR Series voltage transducers provide a fully isolated, 4-20 mA output proportional to rated voltage in sinusoidal situations. Housed in a slim, compact, easy-to-install DIN rail mounted case, the VTR Series comes in a variety of voltage ranges and with four-wire terminal block connection. Phase Loss Protection Voltage Transducer Applications True RMS Voltage Monitoring Detect below normal or “brown out” voltage conditions; protect against possible motor overheating. Identify phase loss conditions by detecting voltage reduction in one or more phase of three-phase motor. Monitor over voltage conditions associated with regenerative voltage to help in diagnosing/avoiding motor drive issues. Detect voltage conditions which may cause stress in or damage to soft starter components (SCRs). Voltage Transducer Features True RMS Output Allows for use in situations where power supplied is poor power quality or other electrically harsh/challenging environments. Standard 4-20 mA Loop-powered Output Industry standard output makes use with existing controllers, data loggers and SCADA equipment easy and reliable. Input/Output Isolation Input and output circuitry electrically isolated for improved safety of use. Compact DIN Rail Mounted Case* Space saving 35 mm wide enclosure mounts quickly for an attractive installation. UL/cUL and CE Approved Accepted worldwide.
