THE UNIVERSAL POWER SUPPLY: WHY EVERY SHOP NEEDS ONE
In the world of trailer diagnostics, uptime is everything. Whether you're running a busy repair bay, managing a municipal fleet, or operating a mobile service rig, there's one piece of equipment that often gets overlooked — power. When testing air brakes, ABS, or electrical systems, the last thing you want is to be tethered to a dead vehicle or hunt down a battery cart. That’s why the Universal Power Supply from Lite-Check is one of the most practical and essential tools any shop can own.
This rugged, compact unit delivers reliable 12V DC power on demand, allowing technicians to perform trailer diagnostics and inspections without relying on the tractor or truck to provide voltage.
Power When and Where You Need It
In many cases, trailers are dropped off without the tractor. That leaves technicians without a power source for lighting, ABS, or brake systems. Without power, you cannot test. That either delays service or forces the use of unreliable workarounds.
The Universal Power Supply eliminates that issue. It provides a clean, consistent 12V power output that can energize the trailer’s electrical systems, lighting circuits, and more — even in the field. Whether you're doing quick light checks or full ABS diagnostics with tools like the Inspector 930 or Advantage 1100, this unit keeps your workflow moving.
Designed for Compatibility
Lite-Check’s Universal Power Supply is engineered to work with all Lite-Check diagnostic tools, including:
Inspector 930
Advantage 1100
STryker 1000
Pro-Check Series
Output Tester 137
Its universal design ensures seamless plug-and-play integration with 7-way trailer connectors and diagnostic test equipment. This means your techs can get set up in seconds and jump right into the inspection without wasted time.
Benefits for Every Fleet Maintenance Operation
1. Prevents Downtime
When you cannot run diagnostics because the trailer has no power source, you lose valuable time. This tool eliminates that bottleneck and keeps your bays productive.
2. Increases Technician Efficiency
The power supply allows for true one-person operation, which aligns with Lite-Check’s mission of “One Person, One Tool, One Process.” Your tech can start inspections immediately, without waiting for a tractor to arrive or another team member to assist.
3. Boosts Mobile Capability
For shops offering field services, the Universal Power Supply is a game-changer. You can perform full trailer inspections roadside or on-location, even with parked trailers or yard units.
4. Cleaner Power, Safer Testing
Compared to jumper packs or modified batteries, Lite-Check’s Universal Power Supply provides clean, stable voltage. That reduces the risk of damaging sensitive components during testing.
