SIL2-Voltage Monitoring Transmitter HVT 300-DX

Application of Voltage Monitor

Typically, the voltage transmitter HVT 300-DX is used in applications which require safety measures to cope with the risk of high voltages. This could be, for example, controlling the access to an automotive test bed or simulation of high voltage powertrain components using a failsafe voltage threshold (for example 50 VDC). Due to the flexible software configuration, the HVT 300 series is suitable for numerous industries and various electrification components.

Scope of use

• Battery
• Battery Management System
• Motor
• Inverter
• Climate Aggregate
• Charger
• Compressor
• HV-Supply

Safety Features

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.
