Dc amplifier operates from 120 V
A brushless dc servo amplifier, the model 526AC, develops +/-15 A
continuously, +/-30 A peak, at motor drive voltages from +/-24 to +/-180
V. Auxiliary outputs are rated +/-15 V and +/-5 V at 20 mA. The amplifier
operates directly from 120 Vac, 50/60 Hz, thus eliminating the cost and
bulk of a separate dc supply. The switching frequency is 25 kHz. The
amplifier is protected against short circuits, excessive temperatures, and
under and overvoltages. ($750–stock to 6 weeks.) Copley Controls Corp.
