Frequently Asked Questions
- What is the Load Bank LB-70 used for?
This load bank is designed for load testing alternators, DC power sources, and vehicle charging systems. It helps technicians confirm system output and detect issues under varying electrical loads, ensuring real-world performance in workshop or diagnostic settings. - How is the load controlled or selected?
The LB-70 offers incremental load steps of 5A, 10A, and 20A, allowing users to apply a precise electrical load up to a total of 70 amps. This flexibility is ideal for simulating different operating conditions during diagnostics. - Does the unit require external power to operate?
No. The LB-70 is self-powered, meaning it draws power directly from the source being tested. This makes it ideal for on-site testing, mobile mechanics, and applications where plug-in power may not be available. - Can it be used for continuous load testing?
Yes. Thanks to its fan-cooled design and 100% duty cycle, the LB-70 is built for continuous operation. It’s safe and stable during prolonged tests, making it suitable for workshops and endurance diagnostics. - Is this unit suitable for test benches and mobile work?
Absolutely. It’s widely used on Durst Test Benches and by field technicians who need to validate alternator output, charging current, or DC supply performance. Its portable footprint and robust construction make it ideal for professional use.
