FEATURES:

• Greater resistance to inverter noise.
• Monitor overvoltages and under voltages 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 over voltages and under voltages.
• World-wide power specifications supported by one Unit (switchable using DIP switch).
• Relay status can be monitored using LED indicator.
