| Kepco's bipolar BOP power supplies are available in 100W, 200W and 400W sizes. For applications requiring higher power, see Kepco's 1KW High Power BOP. For applications requiring higher voltage,
Kepco's Series BOP-HV are available in 500V and 1000V models.
BOP are high speed power operational amplifiers that can be used to provide dynamically
agile voltage for test and simulation. They are not general purpose power supplies. By the
nature of the bipolar high speed design, they do not have any energy-storage noise
discriminating output capacitors. These power supplies offer ultra low noise and ultra low ripple at the output and are MIL-STD-461 compliant. |

Resistive Loads. To realize the full high speed potential of BOP, the load characteristics should be mainly resistive.
Inductive Loads. Kepco's 100W, 200W and 400W L option BOP models are optimized for driving inductive loads. 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. For further guidance on using optimized (L or C suffix) models vs. standard models, see Application Note: When to Use BOP Standard or Optimized (L or C Suffix) to Drive Reactive Loads. Capacitive Loads. Kepco's 100W, 200W and 400W C option BOP models are optimized for driving capacitive loads. This option makes the BOP suitable for a wide variety of applications such as solar cell/panel testing, driving and testing piezo-electric devices, capacitor testing, driving and testing capacitive transducers, and power for industrial or lab applications with capacitive or capacitive-resistive loads. For further guidance on using optimized (L or C suffix) models vs. standard models, see Application Note: When to Use BOP Standard or Optimized (L or C Suffix) to Drive Reactive Loads.

BOP Output Characteristics:
4 Quadrant with smooth crossing through zero 
|
In Kepco¹s BOP, the voltage and current outputs can be controlled smoothly and linearly through the entire rated plus and minus ranges, passing smoothly through zero with no polarity switching.

Remote Digital Control. BOP accept BIT plug-in cards for remote digital control; cards may be factory-installed. BIT 4886 provides 16-bit IEEE 488.2 talk-listen control with SCPI support.
With a BIT 4886 card installed, BOP can also be controlled via a USB port on a Windows 10 computer using KIT 219-0630, available as an accessory. For further details, DOWNLOAD the Instruction Sheet for KIT 219-0630.
BIT 802E provides Ethernet control, offering full control of the bipolar output, either through a web page using a browser or by using SCPI commands via Telnet.
Dual Channel BOP.
Kepco's Series BOP 2X dual-channel BOP models are 200W and 400W power supplies. Each channel is a separate power supply, completely isolated, independent and functionally identical. The 200W units have two 100W channels and the 400W units have two 200W channels. Dual channel models come 
in a single full rack chassis capable of mounting in a standard 19-inch wide rack. The channels are completely isolated, but share two digital front panel meters (without affecting isolation) which display output voltage and current for the channel selected by the front panel Channel select switch. A single power cord powers both channels; separate on-off circuit breakers turn each channel on/off separately.
The two channels are independent. They have separate input control signals and separate output ports. Remote programming can be configured so that each channel operates independently, or the input control can be connected in parallel so both channels are programmed by the same signal.
BOP's are UL listed conforming to 61010-1 safety standard and CE Marked per the LVD, EMC and RoHS 2 Directives. See applicable Declaration of Conformity.
