Servo amplifier is powerful and lightweight

The Castanet, from Elmo Motion Control is an ultra-light, .76 oz [21.5 g], analog servo amplifier. Available in two different models, the 60-volt Castanet provides a continuous current level of up to 3.3 amps (60 volt input) and the 100-volt model provides 2.5 amps. This 330 watt peak and 165 watt continuous miniature servo amplifier delivers high power density. The Castanet can operate as a standalone device or as an integral part of a multi-axis motion system best used by OEM's. Elmo's Castanet operates from a DC power source in current mode and controls both DC brush PM motors and brushless PM motors. External power supplies are used to support 7.5 - 96 volt operation. Important operating features include output linearity and zero dead band performance. Elmo Motion Control, Inc. Westford, MA elmomc.com
