Datasheet

Type of channel connection Simultaneous connection of all channels after power up of the supply
voltage > 20 V, delay time of 25 ms, 100 ms or adjustable "load
optimised" via DIP switch for sequential connection
Efficiency
Efficiency at Vout rated, Iout rated, approx. 97 %
Power loss at Vout rated, Iout rated, approx. 9 W
Switch-off characteristic per channel
Overcurrent switch-off Iout = 1.0 ...1.3 x set value, switch-off after approx. 5 s
Current limitation Iout = 1.3 x set value, switch-off not before typ. 100 ms
Immediate switch-off Iout > set value snd Vin < 20 V, switch-off after approx. 0.5 ms
Reset Using keys for each channel
Remote reset Non-isolated 24 V input (signal level "high" at > 15 V)
Protection and monitoring
Device/Line protection 5 A internal fuse per channel (not accessible)
Status display Three-color LED per channel: green LED for "Output switched
through"; yellow LED for "Output switched off manually"; red LED for
"Output switched off due to overcurrent"
