Model BOP 50-2M (top), Model BOP 100-4M (bottom)

Kepco's bipolar BOP power supplies are available in 100W, 200W and 400W sizes. 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. To realize the full high speed potential of BOP, the load characteristics should be mainly resistive. If the load is capacitive, (>0.1 microfarad), the BOP must be slowed to avoid oscillation. This is accomplished in voltage mode by increasing the value of the feedback capacitance. Special terminals on the user port are available to slow the BOP for optimum current-mode stability into inductive loading.

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.

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.

BOP accept BIT plug-in cards for remote digital control; cards may be factory installed.

• BIT 4882 provides 12-bit IEEE 488.2 talk- listen control with SCPI support.
• BIT 4886 provides 16-bit IEEE 488.2 talk- listen control with SCPI support.
• BIT TMA-27 connect BOP to Kepco's single-address multiple instrument serial bus for long range (>300m) control from IEEE 488.2, RS 232 or VXI-based hosts.
• BIT 488B or BIT 488D offer listen-only GPIB support in binary or Hex format.

BOP are CE Marked per the Low Voltage Directive (LVD), EN61010-1 in accordance with the Conditions of Conformance.
