The two displays and their knobs are assigned to two separately adjustable and working DC output. The third output
is an auxiliary one and can only be adjusted in a very limited range by a trimmer. It doesn’t feature any protections.
Following applies:
• The left-hand display is assigned to the lower pair of DC output sockets and is called “output 1”
• The right-hand display is assigned to the middle pair of DC output sockets and is called “output 2”
• The upper pair of DC output sockets form “output 3”
The meaning of the signals on the display of output 1 and 2 is as follows:
Signal OT
(OverTemperature)
• Overheating of the device
• DCoutputwillbeswitchedo
• Non-critical
Signal OVP
(OverVoltage)
• Overvoltage shutdown of the DC output occurs due to high voltage being generated by
the device or is entering the device from outside
• Critical! The device and/or the load could be damaged
Signal OCP
(OverCurrent)
• Shutdown of the DC output due to excess of the preset limit
• Non-critical, protects the load from excessive current drain
1.8 Technical data
1.8.1 Approved operating conditions
