BTM-090-10 by Copley Controls

The Copley Controls BTM-090-10 from the Bantam M-Axis Controllers series is a compact DC powered analog current amplifier engineered for industrial automation. Measuring 53.3 x 45.7 x 15.2 mm and weighing 0.037 kg, it operates over a +20 to +90 Vdc voltage range and delivers a 5 Adc continuous current with 10 Adc peak current (±15%). Feedback is provided via three digital Hall sensors with a 10 k pull-up resistor and 33 µs RC filter for precise trapezoidal commutation. Protection against short circuits, over-temperature and high-voltage over/undervoltage ensures reliable operation up to 95% non-condensing humidity. Cooling is achieved by conduction through the heatplate or convection, and three open-drain N-channel MOSFET digital outputs support amplifier status, regenerative control and braking functions for versatile motor control integration.
