rmiiteci I Your safe choice HVT 400-DX Failsafe High Voltage Monitor for up to 1.500 V Scope of use Electrification of numerous industries is prevalent. This is especially true for the automotive industry. Voltage levels of next generation powertrains or batteries in electric cars and trucks are increasing. Currently, 800-1200 V is made standard to achieve higher efficiency and faster charging time. This poses challenges to the safety of workers and equipment during manufacturing and testing of high voltage powertrain components using a failsafe voltage threshold (for example 50 VDC). Due to the flexible software configuration, the HVT 400 series is suitable for numerous industries and various electrification components.

Technical Data 1 miitec i I Your sate choice Featuring a safety-by-design approach, the HVT 400-DX provides a wide range of diagnostic functions. In order to create a safety loop, the desired output must be evaluated in conjunction with one of the two diagnostic relays REL3/REL4. This way, two individually configurable safety outputs can be created, for which either the relays REL1/REL2 or the 4...20 mA analog output are available. Main Benefits - Failsafe voltage monitoring - Simple software configuration via USB or Modbus - 0-1500 V DC measurement range (DC and true RMS AC versions are available)...
