Product Description:
The 800-1475 DC servo amplifier is manufactured by Copley Controls and belongs to the DC Servo Amplifiers series. It accepts an external power bus and modulates that energy according to an analog command so that a motor receives armature current proportional to demand. By providing rapid torque control, the module serves positioning tables, conveyors, and other automation axes that rely on tight velocity or force regulation. Integration is accomplished through panel mounting, and standard auxiliary rails furnish logic power for feedback electronics.
During continuous operation, the amplifier can deliver 10 A of output current, while short-duty bursts allow up to 20 A so motors can accelerate quickly. The current loop is observable at a front test point with a scale of ±10 V for ±20 A, simplifying drive tuning with an oscilloscope. To protect connected equipment, the output shuts down if the bus voltage rises above 390 VDC or falls below 45 VDC. Continuous power dissipation is 61 W, indicating the amount of heat that must be removed when the unit is fully loaded. The amplifier measures 7.50 inches wide, 6.94 inches high, and 2.72 inches deep, permitting installation in compact control enclosures without additional brackets.
At idle, the amplifier releases only 7 W of heat, lowering cabinet temperature when connected axes are stopped. If the aluminum heat plate reaches a surface temperature of 70 °C, an internal sensor disconnects the power stage to prevent component stress. The assembly weighs 3.71 lb, making it easier to handle during panel installation. Two auxiliary supplies are available for encoders or signal conditioners: a +5 V supply provides 200 mA, and a ±10 V supply provides 5 mA. The U-to-V phase offset is factory set to 120 degrees to match standard three-phase motor wiring.
