● In the range > 150 % of the selected current response threshold, the current is limited to
150 %, typically after 100 ms, the output is electronically shut down (LED of the output is
lit red).
● When the output current exceeds the selected current response threshold, and if the
supply voltage simultaneously dips below 20 V, then the output is electronically shutdown
(the LED of the output is lit red).

● An output current is continuously permissible up to the selected current response
threshold (LED of the output is lit green).
● In the range 101 - 109 % of the selected current response threshold, an overload current
is permissible for 5 seconds (LED of the output flashes green), then the output is
electronically shut down (LED of the output is lit red).
● In the range > 110 % of the selected current response threshold, the current is limited to
110 %, typically after 100 ms, the output is electronically shut down (LED of the output is
lit red).
● When the output current exceeds the selected current response threshold, and if the
supply voltage simultaneously dips below 20 V, then the output is electronically shutdown
(the LED of the output is lit red).
