Accordingly, our instruments store measured values and compare them to a manufacturer’s limits. Also, a fingerprint obtained in this way can be used at a later stage as a reference during subsequent measurements. In order to obtain an accurate comparison, the tests need to be performed using identical test parameters. Consequently, any deviation and change in the test results may indicate the circuit breaker condition deterioration. Even more, to overcome this issue, DV-Win enables test plans and graph overlay features.Finally, as a final result of a circuit breaker maintenance process, the DV-Win provides analytical tools and customized report creations.

  • Heavy Duty Dynamometers

    MD-7500-HD - Mustang Dynamometer

    Today’s Fleet Managers are faced with many challenges – most important of which is maintaining a healthy bottom line. With fuel costs at an all-time high, these challenges have become increasing difficult. Fleets being transitioned from fossil fuels to electric propulsion also face challenges with durability and range to make sure routes can be completed on time each and every day. To help combat these problems and others facing fleet managers today, Mustang Dynamometer offers the MD-7500-HD Series Chassis Dynamometer – which features the most advanced diagnostic capabilities in the industry. The MD-7500-HD is designed to simulate the driving conditions that fleet vehicles encounter on the road every day in a safe and controlled shop floor environment so that critical engine and drivetrain systems can be evaluated to insure vehicles are performing properly and at maximum efficiency. What’s more, the MD-7500-HD offers several levels of testing capabilities in a modular, compact package and with capabilities that can be upgraded in the future as your needs change. Every vehicle in your fleet can now be tested and validated before and after a repair to ensure proper diagnosis and repairs have been performed. In addition to testing repaired vehicles, the MD-7500-HD can be used to test vehicles on a regular basis as a preventative maintenance measure which decreases unexpected breakdowns and allows fleet management to control fuel costs while reducing repair costs. Periodic testing keeps fuel consumption to a minimum and helps technicians identify suspect components before they fail. A proactive approach to Fleet Service can prevent unexpected engine and or drive-train failure which saves organizations thousands of dollars in lost fair revenues. At the heart of the MD-7500-HD is a set of three air-cooled eddy current power absorbers. Each absorber, or brake, can hold up to 600-hp (total power of 1,800-hp) – more than enough to simulate a fully loaded transit bus. As the systems PAU’s (brakes) are air-cooled, no water is required to or from the device – eliminating the high cost of water consumption and/or the cost of an expensive water recovery system – which can sometimes exceed the cost of the dynamometer system itself. Mustang is the only company that offers a Universal Fleet Test Bed without water supply requirements. AC Motors can be added to simulate regeneration and validate range for organizations that have transitioned to carbon free electric propulsion. The 7500 is the best solution for fleet managers looking to improve their bottom line and offer disruption-free public transportation.
