MDC servo amplifiers for brush-type motors up to 850 oz-inches are MOSFET, pulse-width-modulated, providing four-quadrant control in torque, velocity, and voltage modes. MDC servo amplifiers are available in two voltage ranges, 21 to 80V dc and 40 to 180V dc, and in two current ranges, 6 and 12A. Additionally, an onboard 5V dc 250 mA supply powers an encoder. Measuring 4.43 X 7.3 X 1.6 inches, these inaudible 20 kHz switching amplifiers are available in custom performance ranges and packaging.

The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
