The KSR1 can be supplied by 40 – 250 V AC (45 – 65 Hz)
or 40 – 300 V DC.
Attention: The power supply must be connected as it is depicted on the rear side of the device. A wrong
connection can cause malfunctions or can damage the device.
3.2 Inputs
3.2.1
Measurement input
The KSR1 has a voltage input as well as a current input. Here, the possible voltage range is 0,1 – 20 V and the
measurement range at the current input is 15 mA – 5 A. Both ports can be used for monitoring purpose, but it is not
possible to use both inputs parallel!
