TELL US WHAT YOU NEED Do you have or anticipate having requirements for a power supply to test or power inductive loads? Yes No If yes to the first question, what is the maximum inductance of your load? <2mH 2mH-100mH 100mH-1H >1H If yes to first question, what is your application? motor testing testing magnetic components powering correcting magnets for particle accelerators medical imaging other If you do not receive a confirmation page after clicking submit, please click here. TECH TERMS Bipolar Power Supply 4-Quadrant A power supply able to linearly pass through zero to produce outputs of either positive or negative polarity and able to function in all four quadrants of the orthogonal voltage-current area as either source or sink.	NEW FROM KEPCO: FOUR QUADRANT POWER SUPPLIES FOR MAGNET & MOTOR APPLICATIONS Series BOP Inductive Load Models Kepco introduces 200W (except BOP 200-1M) and 400W BOP models optimized for driving inductive loads as an option to their standard line of BOP power supplies. This option makes the BOP suitable for a wide variety of applications such as motor testing, testing of magnetic components (coils, speakers, etc.), industrial applications with inductive loads, driving CRT coils, cryogenic applications and powering correcting magnets for medical imaging applications or particle accelerators. These 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. All specifications listed below are for inductive load models in Current Mode. All other specifications are identical to the standard BOP. For models not listed, please consult factory. In current mode the bandwidth of the BOP is reduced modestly when operating with a resistive load. 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. (1) All specifications listed are for inductive load models in Current Mode. All other specifications are identical to the standard BOP. (2) 10% - 90%, Nominal Resistive Load. (3) Short-circuit, Nominal Resistive Load (4) Load effect increases nonlinearly with frequency from the typical 0.5 mA in DC full scale (same as the standard unit) with the average rate listed.
