Linear Servo Brush Amplifier drives voice coil linear actuators.

Press Release Summary:

Preset to match continuous and peak current specifications of any H2W voice coil motor, LCAM 5/15 are designed to drive voice coil linear actuators. DC linear brush-type servo amplifier, engineered for low-noise operation, offers 5 A continuous and 15 A peak output. Operating from +24 to +70 Vdc supply, product has 6.5 kHz (90° phase shift) bandwidth and supports current or velocity mode operation. Amplifier Enable input and Fault Indicator output are standard features.

Original Press Release:

Linear Servo Brush-Type Amplifier

H2W introduces a new DC Linear Brush-Type Servo Amplifier (LCAM 5/15) that is ideally suited to drive our complete line of voice coil linear actuators. Since the majority of voice coil actuators have very low inductance windings (less than 1 mH), the preferred method to drive these voice coils is with a linear servo amplifier. Amplifiers will be preset to match the continuous and peak current specifications of any H2W voice coil motor. Available from stock for immediate shipping.
