- 1. Analog Servo Drive BDC30A8 Description Power Range Peak Current 30 A Continuous Current 15 A Supply Voltage 20 - 80 VDC The BDC30A8 PWM servo drive is designed to drive brushless DC motors at a high switching frequency. It is fully protected against over-voltage, over-current, over-heating and short-circuits. The drive interfaces with digital controllers that have a digital PWM output. PWM IN determines the output current. DIR determines the direction of rotation. A single red/green LED indicates operating status. See Part Numbering Information on last page of datasheet for additional ordering options.

- 2. Analog Servo Drive BDC30A8 BLOCK DIAGRAM Information on Approvals and Compliances US and Canadian safety compliance with UL 508c, the industrial standard for power conversion electronics. UL registered under file number E140173. Note that machine components compliant with UL are considered UL registered as opposed to UL listed as would be the case for commercial products. Compliant with European CE for both the Class A EMC Directive 2004/108/EC on Electromagnetic Compatibility (specifically EN 61000-6-4:2007 and EN 61000-6-2:2005) and LVD requirements of directive 2006/95/EC (specifically EN 60204-1:2006), a low voltage directive to protect users from electrical shock. RoHS (Reduction of Hazardous Substances) is intended to prevent hazardous substances such as lead from being manufactured in electrical and electronic equipment.
