Hall Sensor Amplifier from Portescap

Portescap has introduced its RoHS-compliant EBL-H-50-03 four-quadrant amplifier. With fully programmable features, this hall sensor amplifier is engineered to optimize the performance of Portescap brushless motors in applications where efficiency, high acceleration or safety is primary significance, such as Bi-PAP respirators. All inputs and outputs are clearly identified to facilitate easy startup in less than 10 minutes. The EBL amplifier can be customized by the factory for spe-cific application by programming the level of current protection and PI regulation parameters. With a compact footprint of 92 x 72 x 16 mm and weigh just 45 grams (1.5 oz), the EBL amplifier is ideal for portable equipment applications where size and weight are significant design considerations.

A broad supply-voltage range of 5.5 – 50 V enables accurate control of 16-30mm brushless motors at speeds up to 90,000 rpm. They also provide continuous current out-put of 3 amps, and maximum current output of 12 amps. Thermal, short and over current protection are included as standard, while an optional start up current limitation feature helps protect surrounding equipment (such as a battery pack).
