Product Description:
A compact heavy-duty 4122DC servo amplifier manufactured by Copley Controls presents advanced configuration options. This small amplifier has the dimensions of 85 mm x 85 mm x 50 mm and its weight is only 0.43 lbs. It can handle power within the range of ~20A at a voltage of ~80V. The 4122 also has a PWM switching frequency of 25 KHz and therefore has the capability to respond to changes in loads while at the same time ensuring minimal ripples in the output voltage. Its protective features consist of two main elements. The first protects the device from short circuits while the second monitors temperatures above 70 degrees Celsius to improve overall system reliability.
The 4122 operates when its load inductance ranges between 200 ?H and 40 mH. The output voltage is dynamically regulated according to the equation: HV*(0.97) ~ (Ro)*(Io) where Ro is the output resistance of the circuit (0.2?). It can control the voltage with high precision and also sustains the operations. Overall, with an operational bandwidth of 3kHz and a supply current of 23mA, it is highly suitable for high-speed motion control applications. It operates at a low supply current of 23mA when driving a load of 200?H.
With regard to size and installation compatibility, the 4122 is suitable for numerous settings due to its compactness. It has an input supply of +22 VDC to +90 VDC. It has a differential reference input which has upper and lower voltage limits of ~ 20V which can be used to control the speed and position of a motor. These features coupled with high power density and sturdy construction make the Copley Controls 4122 suitable for several Industrial and Robotics applications.
