VMR 3P PR07(RELAY)

Description

• Supply Voltage: 3-Phase 415V AC, 50 Hz (R, Y, B & N).
• Auxiliary Supply: None required; it draws power directly from the monitored input.
• Output Contacts: Two SPDT (C-NO/O-NC) relay outputs, rated at 5A, 250V AC.
• Mounting: Standard DIN Rail.
• Physical Dimensions: 55(W) x 75(H) x 110(D) mm.
• Default Setpoints: Under-voltage default 360V; Over-voltage default 450V; Unbalance default 70V. [1, 2]
  Key Protective Functions
  • • Under/Over Voltage: Trips if voltage falls below or exceeds user-defined limits.
    • Single Phasing Preventer (SPP): Instantly disconnects power if any single phase fails.
    • Reverse Phasing: Shuts down the system if the phase sequence is incorrect.
    • Voltage Unbalance: Detects unbalances between phases that cause motor overheating. [1, 2]
  Interface & Indicators
  • • Digital Display: Shows current running voltage data and explicit fault text messages.
    • LED Status Flags: Dedicated Red LED for faults (UV, OV, SPP) and a Green LED indicating the relay status is active.
    • 3-Button Settings: Built-in SET, UP (INC), and DOWN (DEC) keys for easy field calibration. [1, 2, 3]
