Voltage Transmitter HVT 300-DX

Product catalog summary

Application
The HVT 300-DX is designed for high voltage monitoring up to 1000 V DC, particularly useful in the electrification of industries such as automotive, where next-generation powertrains and batteries operate at 800-1200 V. This device addresses safety challenges during manufacturing and testing by providing a failsafe voltage threshold.

Scope of Use
The device is applicable to various components including batteries, battery management systems, motors, inverters, climate aggregates, chargers, compressors, and HV supplies.

Safety Features
The HVT 300-DX employs a safety-by-design approach with diagnostic functions to create a safety loop using diagnostic relays REL3/REL4. It offers two configurable safety outputs and features LED status indicators for power, error, and alarm.

Technical Data 1 miitec i I Your sate choice Featuring a safety-by-design approach, the HVT 300-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...20mA analog output are available. Main Benefits - Failsafe voltage monitoring - Simple software configuration via USB or Modbus RTU - 0-1000 V DC measurement range - Redundant architecture - Robust...
