CASE STUDIES
Buses used for student transportation are increasingly equipped with sensitive electronics for tasks like attendance tracking and route planning. However, the 12V power supply in buses is highly unstable, especially during startup. Voltage sags caused devices to reset or shut off creating headaches for drivers and introducing the risk of missing critical operational data. The customer needed a rugged, compact voltage booster that could stabilize power and operate reliably in harsh conditions.
Steiner Enterprises developed a robust 12VDC voltage booster, purpose-built for school bus environments. The unit was designed to filter and regulate the power supply during cold starts and voltage dips — keeping downstream devices powered and operational. The enclosure and circuit were engineered to withstand temperature extremes, continuous vibration, and electrical noise common to bus electrical systems.
Maintains consistent voltage during low-startup or noisy input conditions
Designed for hot, cold, and high-vibration vehicle environments
Easily integrates into existing equipment mounts
Reduced parts count and improved classroom durability
Assembled in the USA with international components
The voltage booster gave the customer a reliable power backbone for their electronic systems. It eliminated costly troubleshooting and boosted confidence for end users by ensuring startup stability without manual resets or data loss. This product has since been integrated across a range of bus models and equipment configurations.
