TRD System

VRLA Battery Thermal Runaway Detection System
  • Part Number: Consult with Alpha for PN
  • Product Line: Distribution
TRD System
  • Modular, hot-swap circuit card assembly
  • Two remote temperature sensor probes
  • Temperature display
  • Pre-alert and Thermal Runaway alarm relay contacts
  • Optional self-disconnect feature
  • The Alpha TRD (Thermal Runaway Detector) system complements our DCX battery disconnect systems to create the only self-contained Telecom grade thermal runaway detection AND auto-disconnect system which comply with both NFPA and State/Local fire codes for VRLA battery installations.

    The TRD controller circuit monitors temperature in three locations to analyze and determine if the VRLA battery system is approaching or is in thermal runaway condition. Two remote battery terminal sensors are compared against an internal reference temperature sensor and the differential is analyzed. Should a thermal fault be detected, the system alerts this status.
