User Manual a predetermined nominal current value during the time of 0 1 sec allowing the current to be slowly sourced to an SLD module With this feature in use an overdamped switch on response of the driver without any overshooting over the nominal current setting is guaranteed Moreover the time of 0 1 sec is long enough to eliminate a sharp temperature related current impact on the TEC at start up therefore high reliability for the TEC operation throughout its lifetime is ensured Another benefit of the 0 1 sec start up time is that all turn on transients in the driving current completely die out during this time before applying the current to an SLD thereby not affecting the SLD operation It is important to note that in most cases applying these transients to an SLD leads to either its catastrophic destruction or parametric degradation of its performance Clamping limit circuit for SLD current This circuit provides a clamping limit for the SLD driving current so that an SLD is effectively prevented from overdrive by an excessive current above the limit point commonly called limiting threshold To help the user identify the situation in which the driving current has reached the limiting threshold a LED indicator called Service has been added on the front panel of the BroadLighter Once the current has reached the limiting threshold the LED lights up thereby showing the user that the current is being limited Automatic p
