Ideal for 3-phase voltage asymmetry monitoring for industrial facilities and equipment.

• Monitor voltage asymmetry, 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.
• One SPDT output relay, 6 A at 250 VAC (resistive load). • World-wide power specifications supported by one Unit (switchable).
• Relay status can be monitored using LED indicator.
