Output Conditioning Selection
The 5620 Power has a jumper-selectable output conditioning feature, located on the lower
circuit board, that changes the output voltage response time (Fig. 3-3).
This feature protects the controller from excessive in-rush current when connected to resistive
loads that have low resistance when cold. The three different response time settings are:
Fast: For resistive loads where the cold-to-hot resistance is nearly constant. (.045 sec
response time)
Ramp: For rapidly responding resistive loads where the load resistance increases less
than twice from cold to hot. (1 second response time).
Lamp: For rapidly responding resistive loads, such as tungsten filament lamps, where the hot
resistance is more than twice the cold resistance. (5 second response time).
