12BOutput 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).

Figure 3-3 Jumper positions for Fast, Ramp, or Lamp response time settings.
