Trumeter VMR03 Voltage Monitor Relay, 5s ON delay, 0.5 to 15s time delay

The VMR Series voltage monitoring relays are engineered to improve reliability and efficiency across general industrial and white goods applications. These compact, DIN-rail mountable relays feature true RMS measurement for accurate monitoring on three-phase, 3-wire systems (208–480V).

Ideal for applications requiring dependable voltage protection and flexible setup, the VMR Series offers smart monitoring in a space-saving footprint.

Key Features:

• Multi-voltage input support for broad compatibility
• Self-monitoring and fault detection across one or more phases
• Protection against: Over-voltage (OV), Under-voltage (UV), phase asymmetry, phase loss, incorrect phase sequence, three-phase interruptions
• Selectable supply voltage with adjustable trip points for UV, OV, and phase imbalance
• Configurable ON/OFF time delays to suit system requirements
• Single Form C (changeover) relay output for reliable switchingv
• Compact 17.5mm DIN-rail enclosure for easy installation
• LED status indicators for real-time fault alerts and dip switch change detection
