OPTIMIZE BOP 200W AND 400W
FOR DRIVING CAPACITIVE LOADS
TO 10 MILLI-FARADS
8
For digital meters, substitute the letter D for M when ordering - example: BOP 20-20DC.
For GPIB control of the BOP, add the suffix 4886 after the letter C in the model name -
example: BOP 20-20MC4886.
(1) All specifications listed are for capacitive load models in Voltage Mode.
(2) For BOP 20-20MC, DC: nonuniformities of the frequency response creates a larger 3-dB bandwidth
for the resistive load than for the standard BOP.
(3) Nonuniformities of the frequency response for the standard 10μF load create a larger 3-dB bandwidth
than for the resistive load.
(4) 10% - 90%, with nominal resistive load.
(5) Load between infinity and nominal resistive values.
As an option (C suffix), Kepco's 200 Watt (except
BOP 200-1M) and 400 Watt BOP models may be
optimized for driving capacitive loads.
These BOP units are designed to operate in a stable
manner in voltage or voltage limit mode for capacitive
loads up to 10mF. They are also stable when driving
any R-C parallel combination where load R is ≥
nominal value and C is ≤10mF. Load R (nominal value)
= nominal output Voltage/nominal output Current
(e.g., BOP 36-6MC, R = 36/6 = 6 Ohms). To prevent
current limit operation, the equivalent impedance of
the R-C parallel load circuit at the working frequency
must be greater than the nominal R value.
Static specifications representing accuracy for various
influence parameters are identical to the standard
BOP models. Ripple and noise specifications are better
(approximately 50% lower) for the C option units
compared to the standard BOP.
In voltage mode, with a resistive load, the
bandwidth of the BOP Capacitive Load is reduced
versus the standard model, while the response time is
increased (except the 20V model: see Specifications
Chart). The frequency response variations can be
practically eliminated by reducing the bandwidth in
voltage mode in a predictable manner using an
internal user-installed component to increase the
internal compensation capacitance (see Bandwidth
Correction Chart).
In Current Mode the dynamic specifications are
almost identical for all BOP C option models: 3-dB
bandwidth of 4.9kHz and rise/ fall time of 72µsec
(lower bandwidth and higher rise/fall time than the
standard BOP models).
