3 Phase Detection & Sequence Analysis
- Micro-Controller based system using resistor type sine detection (50Hz) for all the three phases.
- +5V Zener based supply from 440V AC to 12V AC Step down transformer.
- +12V Relay – 7A Output – either latch or trigger type, when any one phase fails.
- Low Cost & Easy to install.
- LED Indication for the phase fault sense.
