Kepco Inc. has introduced 200 W and 400 W bipolar operation power (BOP) supply models optimized for driving inductive loads. The modified BOP units are designed to operate in a stable manner in current or current-limit mode for loads up to 1 Henry. 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 (model dependent). Further, it is possible to predictably reduce the bandwidth in current mode using one customer-installed component on the rear programming connector of the BOP.
According to the company, this option makes the BOP more suitable for a wide variety of applications, such as solar cell testing.
