High-Amp Compact Low Voltage Disconnects Series - 250A - Compact LVD - The Most Powerful LVD Available

DataSheet:Download 48514 LVD Datasheet

Littelfuse Compact Low Voltage Disconnects electronically sense battery voltage and conserves starting power. The unit automatically disconnects and reconnects loads based on battery conditions which prolongs battery life by preventing damage due to excessive discharge.

When battery voltage falls below a programmed voltage settings for 2 minutes, non-critical loads are automatically disconnected.

Features & Benefits

  • The most powerful solid-state LVD available! 
  • Auto-ranging identifies whether system is 12V or 24V, and automatically establishes thresholds (one part number; two voltages)
  • Metric tin-plated copper terminals
  • Eliminates dead battery service calls and lost time. Extends battery life by preventing irreversible damage due to excessive discharge. 
  • Unit gives warning one minute before disconnect through a 250 mA alarm signal that can drive audible or visual systems
  • Optional manual override feature.
  • Can be mounted in harsh environments – sealed to IP67, with sealed Deutsch connector.
  • Solid state reliability and resistance to vibration – replaces vulnerable conventional solenoids. Unit exceeds one million cycles and is protected from over-temperature, overcurrent, overvoltage, and under-voltage.
  • Minimal draw on battery (only 1mA standby).
