Product Description:

Copley Controls introduced a 4212 DC servo amplifier that is an upgraded one for operation in the most challenging manufacturing environments. Its most prominent characteristic is the PWM switching frequency of 25kHz, which is responsible for fine and immediate control of motor operations. The switching frequency frequently reduces ripple currents and increases the efficiency of the motor control system. Also, the amplifier reference input and the maximum voltage of ~20V ensure the stable and accurate signal conversion of the amplifier.

The power supply requirements for the 4212 servo amplifier are moderate where the voltage inputs range from +22VDC to +125VDC. An advantage of this wide input voltage range is it makes the amplifier suitable for different industrial settings. The power output features a continuous power of ~6A at ~120V whereas the pulse power output is ~12A at ~120V thus making the amplifier suitable for applications that require both constant power and high surge power. The power and motor connections involve the Phoenix MKDS 3 connectors which make installation easier and make sure that there are safe electrical connections.

In regards to performance, the 4212 servo amplifier has a bandwidth of about 3 kHz at 200 uH load, which is essential to control the motor operations. The inductance of the amplifier can vary from 200 uH to 40 mH, however, the application of this type of amplifier is versatile and can be used in almost any type of motor system. The operating temperature range of 4212 is 0 to 70 degrees C and it is compact with 4.3 x 3.0 x 1.0 inches dimensions which means that it cab operate under various industrial conditions. It has high rigidity which is a significant feature to facilitate the enhancement of speed and accuracy for motor control systems.
