LINETRAXX® VME420
- Undervoltage, overvoltage and frequency monitoring of AC/DC systems 0…300 V
- Various monitoring functions selectable < U, > U, < f, > f
- Adjustable start-up delay, response delay and delay on release
- Password protection for device setting
- Preset function (automatic setting of basic parameters)
The VME420 series voltage relays are designed to monitor the frequency, undervoltage, overvoltage and the voltage between two threshold values in AC and DC systems. The voltages are measured as r.m.s. values. The currently measured value is continuously shown on the LC display. The measured value required to trigger the alarm relay is stored. Due to adjustable response times, installation-specific characteristics, such as device-specific start-up procedures, short-time voltage fluctuations, etc. can be considered. The relays require an external supply voltage.
