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.

Resistive Loads. To realize the full high speed potential of BOP, the load characteristics should be mainly resistive.

Inductive Loads. Kepco's 200W (except BOP 200-1M) 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.

Capacitive Loads. Kepco's 200 Watt and 400 Watt 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.

Operational Amplifier. BOP, while fully rated power supplies, are also high-powered operational amplifiers with full 4-quadrant, bipolar operation. Their output is capable of both sustained d-c and the replication of arbitrary a-c waveforms. The Kepco's BOP is the recommended operational amplifier for measuring Power Supply Rejection Ratio in an Audio Precision Knowledge Base Technote.

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.

BOP are CE Marked per the Low Voltage Directive (LVD), EN61010-1 and the EMC Directives. See applicable Declaration of Conformity and the Conditions of Conformance.
