KDS4 - amplifier for magnetic brakes
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.
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).
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.
Setpoint 0 .. 10V referenced to GND
10V no outward
Brake coil can be reversed
Slim DIN rail
Replaceable fuse on the front
24VDC / 100mA, reverse polarity without braking power, protected by a fuse
4-quadrant power stage with PWM control
4A, current pulse for 1s
Start on input 0 – 10V corresponding to 0 – 100%
0 … 50% adjustable by potentiometer
On optocoupler, typically 24V /> 12mA,
Low = <1V, High => 8V
Contact open = alarm, closed = ok
Is activated after about 1s > 2.5A and remains pending until receipt
Potential free NO contact, 30VDC/1A, 125VAC, 0.3A
Clearing the alarm output
Switching 1Q / 4Q jumper in the front panel
We only read at power
Green = Power
LED green = start
LED red = alarm
