characteristics of brake-controller, type b...

purpose

Devices of type b... are thyristor-controlled and are used for a controlled deceleration and accurate landing with 3-phase ac-motors.

general

• designed for speeds up to 0.63 m/s (type b...)
• relays for the power contactors and the mechanical brake (controlled by the rated value and the actual value of the speed)
• analog and digital sensor input on the same circuit card
• the brake-controller provides a dc-current which has to be supplied to the motor
• brake-controller of type b...pi use a 2-phase rectifier and devices of type b... use a 3-phase rectifier.

technology

• potentiometers for actual speed and deceleration distance
• input: 2 x 400 VAC, 230 VAC, operate-signal via an external relay-contact
• output: relay-contacts (4A/250Vac) for the power-contactors and the mechanical brake
• monitoring: rated value - actual value
• installation: vertical
• ambient temperature: max. 45 °C / 113°F
• enclosure: IP00
• duty-cycle: 30%
