Linear Current Amplifer Module (LCAM)
High-precision machines and drive systems will benefit from Quanser’s robust and compact Linear Current Amplifier Module (LCAM). When operating in current mode, Quanser’s OEM dual-mode linear amplifier is best suited for precision controls to drive inductive loads such as voice-coil actuators, coreless DC motors, magnetic bearings and the like. Alternatively, the LCAM can also operate in voltage mode.
Applications which exclude the use of standard PWM amplifiers because of stringent noise requirements (or applications where dither due to PWM signals is unacceptable) can utilize the low-noise, wide-bandwidth and cost-effective LCAM. Industries incorporating the LCAM technology include: high-precision machine tools and robots, metrology and instrumentation, nanotechnology (MEMS), microelectronics, optical fabrication, photonics, automotive, and many others.
Designed to run from a single power supply (with a rating ranging from 27 to 60 VDC), the LCAM can deliver a maximum continuous current of 7 A and has a peak current capability of 10 A. The LCAM also includes accurate current sensing, current limiting, thermal protection and selectable gains for the built-in closed-loop current controller.
