Solenoids and Solenoid valves are found in many of the subsystems used to assist in control of a variety of vehicles. Solenoids are used on off-highway construction equipment, buses and trains as components in their brake control systems, shifting, sleet brushes, track head conditioning equipment and door opening/closing systems, sanding control systems, de-couplers etc.
High performance miniature valves for battery-based devices.
- Fluctuating supply voltage
- Wide range of ambient temperature
Our solution ADRV0002: it makes the switching independent on the external parameters.
Circuit Breakers in power converters Typical applications are found in trains and power stations.
Challenge: Reliability of the breaker.
Our solution ADRV1003: Consistent switching for push and pull functions.
Example: Door locking in elevators
Problem definitionA small solenoid that needs high pull in force has to operate in a confined space. The coil heats above 120°C. The customer is using a temperature switch to turn-off the solenoid when it over-heats. This solution is not comfortable and is expensive.
Proposed solutionFor this customer, we developed a miniature electronic circuit that regulates the power for the solenoid. The temperature is reduced to 60°C with sufficient holding force to maintain the door in its position.
