-48V DC Cable Breaker Module

-48V DC Cable Breaker Module

Part Number: QTL2834 / QTL2861

Product Details

Incorporate power cycling / power testing for -48V powered telecommunications equipment.

The -48V cable breaker is an automated solution for hot-swap testing and fault injection on ELCON Mini 2-pin connectors. Automation provides easier, faster, and more detailed testing. Consistent, repeatable results reduce time to market and improve reliability.

This device makes a great complement to our SFP and RJ-45 breakers, allowing control over the data links and power supply to telecommunications equipment.

This module requires the purchase of a separate controller.



  • ELCON Mini 2-pin connectors
  • Power cycle the supply
  • Simulate intermittent faults
  • Improve test coverage while decreasing duration
  • Ideal for bench testing, debugging, and evaluation
  • Up to 4 modules can be rack mounted in 1U


  • Requires Torridon Array Controller or Interface Kit
  • Individual control over power and present signals
  • Glitch and pin-bounce at ~3uS minimum period
  • 20A max at -48V
  • Supports voltage range from -25V to -72V



This is the basic module


This version has the addition of 2 SMA connectors for external trigger IN/OUT. This allows the module to connect to to an external analyser or similar. You can then cause a hot-swap or glitch to occur at a precise time within the data stream.
