For digital meters, substitute the letter D for M when ordering - example: BOP 20-10DL.
For GPIB control of the BOP, add the suffix 4886 after the letter L in the model name -
example: BOP 20-10ML4886.
(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) at the average rate listed.
As an option (L suffix), Kepco’s 200W (except BOP
200-1M) and 400W BOP models may be optimized
for driving inductive loads. 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.
To prevent voltage limit operation, the equivalent
impedance of the R-L series load at the working
frequency, must be lower than the nominal resistive
load value (nominal output voltage/nominal output
current).
All specifications of the unit in voltage mode are
unchanged from the standard model. The specifications
listed in the table to the right are for inductive load
models in Current Mode. All other specifications are
identical to the standard BOP.
In current mode the bandwidth of the BOP is reduced
when operating with a resistive load. Correspondingly,
the rise and fall time of the unit is increased (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 (see Bandwidth
Correction Chart).
