KDS4 - amplifier for magnetic brakes

KDS4 - Verstärker für magnetische Bremsen

Description

Compact power
24V operating voltage
4A peak current

This new amp for the 24V voltage range provides high-tech in a small space. The integrated, powerful processor ensures accurate current setting and monitoring occurring current spikes.

Intelligent Control
By jumper on the front of fashion can be changed. So you can run both standard Q-1 magnetic braking and braking with deletion of the magnetic Restremanenz in 4-Q mode.

An LED display informs the user about the status of the start input and the response of the device (alarm output).

Reliability
Of course, the start input of the amplifier via opto-isolated from the operating voltage, the alarm output is a potential free contact.

A transparent cover protects against accidental operation.

Improvements
Setpoint 0 .. 10V referenced to GND
10V no outward
Brake coil can be reversed
Slim DIN rail
Replaceable fuse on the front
