- Greater resistance to inverter noise.
- Monitor overvoltages and undervoltages for three-phase 3-wire or 4-wire power supplies. DIP switch setting for 3-phase 3-wire or 3-phase 4-wire power supply.
- Two SPDT output relays, 5 A at 250 VAC (resistive load). Separate outputs possible for overvoltages and undervoltages.
- World-wide power specifications supported by one Unit (switchable using DIP switch).
- Relay status can be monitored using LED indicator.
