Overvoltage/Undervoltage Monitoring Relay for AC and DC Input

Description

• Detect overvoltages or undervoltages (switch selectable) from 4 mV to 300 V.
• Detect undercurrent, reverse current, or overcurrent in DC circuits using shunt (SDV-FL).
• Detect three-phase AC current for under and/or overcurrent using current converter.
• Available in 7 supply voltage configurations.
• Single-function model with ON-delay, OFF-delay, or startup lock settings (SDV-FH@T).
• Select either AC or DC voltage input.
• Polarity can be specified (SDV-FL) to enable easy reverse current detection.
• Selectable reset value range from 2% to 30% of operating value (SDV-F).
• LED operation indicator.
• UL, CSA (SDV-F), and RCM approval.
