Dahl?
The RLDD015H-350H is a high power switching mode carbon sensor driver from Royal Dahl. It is designed for applications requiring both high temperature operation and high current control. The device is capable of running with up to 350W output in a wide range of operating temperatures. It features a special design that allows the switching frequency to be reduced from its nominal frequency to below 500Hz, providing a much more efficient operation when used in high temperature applications. It also provides protection against voltage transients and an adjustable over-current protection. The device can also interface with multiple communication interfaces such as RS485, USB and GPIO.
