Lind PAUPS1221-3994 12V Smart Battery Backup & Delay Timer Modules
Looking for a reliable, heavy-duty mobile power solution for your fleet, security network, or DIY 12V off-grid build? This unit originally engineered for law enforcement vehicle networks (Panasonic Arbitrator Systems) and now ready for versatile deployment.
Every single unit in this lot has been individually bench-tested in our workshop to verify full operational integrity, relay switching, internal cell retention, and fuse protection. They are 100% functional and ready to install.
🌟 What Makes These Modules So Valuable?
These are not simple relays; they are intelligent 12V Uninterruptible Power Supplies (UPS) with built-in vehicle ignition sensing.
* Ignition-Sensing Delay-Off: Connect the white trigger wire to your ignition switch. When the engine shuts off, the module stays active, keeping your electronics powered for a pre-programmed delay window before shutting down safely to preserve your starter battery.
* Seamless Backup Power: Features internal secondary backup cell capability to smooth out voltage drops, engine cranks, and sudden power disconnects.
* Integrated Safety: Features a built-in, easily accessible 10-Amp mini blade fuse directly on the top faceplate to protect expensive downstream electronics.
🚐 Ideal Applications:
* Fleet Equipment & Upfitters: Perfect, drop-in replacement spares for police, fire, EMS, and municipal electronics grids using Panasonic Arbitrator systems.
* Van Life & RV / Overland Builds: Manage auxiliary 12V electronics (Wi-Fi routers, GPS trackers, mini-fridges, LED controllers) without worrying about draining your main vehicle starter battery.
* Mobile Security & Dashcams: Power multi-camera mobile DVR units or parking-mode dashcams seamlessly without risking your car’s electrical health.
