Multifunctional three-phase monitoring relays
- Use the principle of True RMS to measure
- There are 2 sets of contacts inside the device to choose from (2C/O).
- Small size only 22 mm. Easy to install with DIN Rail mounting.
- Detect voltage drop, over voltage, lost voltage, reverse polarity voltage.
- You can set the operation of the contact unit to ON-delay or OFF-delay on the device page.
- The reverse polarity voltage function can be turned on.
- Delay time can be set from 0, 0.1-30 seconds.
- 3 LEDs show the working status of the device.
