The 200 and 400 W Bipolar Operational Power Supply (BOP) models for driving inductive loads are stable in Current or Current Limit Mode for loads up to 1 H. They are also stable with any R-L series load combination.
All specifications of the unit in voltage mode are unchanged from the standard model. In current mode the bandwidth of the BOP is reduced modestly. Correspondingly, the rise and fall time of the unit is increased somewhat (model dependent). Further, it is possible to reduce the bandwidth in current mode, in a predictable way, using one customer-installed component on the rear programming connector of the BOP.
