Product Description:

The Copley Controls 5121 drive is a high-performance DC servo amplifier suitable for demanding applications. This small unit with a shipping weight of only 1.1 lbs has a maximum current rating of ~20 A at ~83 V, hence it can easily be used to drive high-power motor loads. By using the 25 kHz PWM switching frequency, the device offers an almost immediate response to changes in the input voltage and minimizes the ripple in the output voltage. These amplifiers deliver high torque efficiency at low speeds which makes them perfect for applications like robotics, CNC machines and automation systems.

The amplifier exhibits a 3 kHz bandwidth rate thus making it ideal for applications that require quick motion control. The amplifier uses differential reference input signals for independent monitoring and regulation of analog signals while maintaining a reliable short circuit protection system to safeguard the device. This device operates across different temperature ranges because its durable construction enables operation under challenging conditions. The device features a wide temperature storage range between -30 degrees C and + 85 degrees C which allows transportation and storage under any climate conditions. The 5121 drive can be operated when the baseplate temperature ranges between 0 degrees c and 70 degrees c. This wide operating temperature range shows that the device is suitable for use in any industrial setting and areas where there are frequent temperature changes.

The compact dimensions combined with the low weight allows the operation of this device in any system. Such benefits like high power density as well as highly consistent performance in low and high temperatures make the Copley Controls 5121 ideal for various operations in industrial automation, robotics, and any other motion control equipment.
