Product Description:
The EL9576 brake chopper terminal is a Beckhoff product that is designed for industrial automation. Beckhoff is recognized for its extensive selection of robotics and drive technology options that are compatible with control systems. The brake chopper terminal is designed to keep supply levels stable and handle the drive systems' regenerative energy.
The EL9576 brake chopper terminal has a technology that enables it to operate at a minimum voltage of 72 V. The connector has a 155 µF capacitor. It can handle a ripple current of up to 10 A and has an internal resistance of less than 5 mΩ. The voltage of the chopper can be changed, and a 10 Ω braking resistor with a power limit of 100 W is usually best for most uses. The overvoltage control range is usually 1 V, and CoE data can be used to set the parameters. The braking resistor clock rate depends on the load and can go up to 100 µs. It uses a two-point control method. Between the E-bus and the field potential, there is 1500 V of electrical separation. The brake chopper terminal can be connected to servomotor, DC, or stepper terminals. It also has an adjustable cutoff for precise energy management. The item is meant to handle return currents and avoid overvoltages by releasing extra energy through an external brake resistor when the capacitor's capacity is reached.
The EL9576 brake chopper terminal has extra features that help it work efficiently and safely. The terminal is about 90 grams heavy and can work in temperatures ranging from 0 to +55°C. It can also be stored in temperatures ranging from -25°C to +85°C. The humidity level can go up to 95% without condensation, and it meets the standards for EMC protection and emissions EN 61000-6-2 and EN 61000-6-4.
