• Greater resistance to inverter noise.
• Monitor overvoltages, undervoltages, phase sequence, and phase loss for three-phase 3-wire or 4-wire power supplies with just one Unit. 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). Output overvoltages and undervoltages using separate relays.
• World-wide power specifications supported by one Unit (switchable).
• Output status can be monitored using LED indicator.
