It is designed for interfacing the driver with the customer electronics, power supplies and measuring equipment and is very handy for limited volume production or to allow the testing of systems before the customer's electronics is ready. Together with the -E2 drivers, they were designed to control Boreasa blowers. For more details about the -E2 drivers, refer to the D30/x/xQx-E2 literature. • Drives one BLDC motor (up to 30 V and 10 A) • Speed and Current limiting modes • Designed for Boreasa blowers, but suitable for various motor requirements • Robust 30 VDC power supply interface • Reverse polarity protection Typical hookup drawing:

So the power supply voltage HAS TO BE lower than 30 VDC.
