The Kepco BOP15 is a bipolar operational power supply that functions as a high-powered DC-coupled operational amplifier for precision voltage and current control. Its four-quadrant output architecture enables simultaneous sourcing and sinking of current, permitting smooth bidirectional power delivery and arbitrary AC waveform synthesis without polarity switching. The BOP15 operates without output energy-storage capacitors, delivering high-speed dynamic response with primarily resistive loads.
## Technical Specifications
• **Output Configuration:** Bipolar, 4-quadrant (source/sink)
• **Operational Mode:** High-speed power operational amplifier, DC-coupled, inverting configuration
• **Load Optimization:** Designed for resistive loads; capacitive loads >0.1 µF require feedback capacitance adjustment to prevent oscillation; inductive loads up to 1 H supported via optional “L” models or external current-mode stability terminals
• **Current Protection:** Built-in current sensing with protective limiting at approximately 110% of rated current; internal clamp with ~2-second reapplication delay circuit
• **Output Monitoring:**
– Voltage monitor: Eo Monitor Output (pin 20, PC12 connector) with 5 kΩ series resistor; buffered, no overvoltage protection
– Current monitor: Io Sensing Output (pin 10, PC12 connector); unbuffered with short-circuit risk
• **Reference Supply:** Two ±6.2 V ±5%, 1 mA references
## Key Features
• Four-quadrant bidirectional power delivery with zero-crossing capability
• Capacitor-free output design enabling high-frequency response
• Dynamic agile voltage and current control
• Programmable operation via analog (voltage/resistance) or digital control
## Programmability & Control
• **Analog:** Local control or external analog voltage input
• **Digital:** IEEE 488.2 (GPIB) with SCPI support; Ethernet/LAN interfaces; Kepco SN 488 Digital Programmer; BIT TMA-27 serial bus control option
## Load Protection
Inductive load protection requires external bipolar transorbs, crowbar elements, or AC normally closed contactor connected directly at output.
