The Kepco BOP-36-12M is a high-speed, four-quadrant bipolar power operational amplifier delivering 400 W of output power for precision signal control and dynamic waveform synthesis. It sources and sinks 100% of its ±12 A current rating across a ±36 V range, operating through zero without polarity switching. Purpose-built for test and simulation environments requiring real-time voltage and current command tracking, this amplifier prioritizes dynamic response over energy storage, making it unsuitable as a general-purpose power supply.
## Technical Specifications
• **Output Power:** 400 W
• **Voltage Range:** 0 to ±36 V
• **Current Range:** 0 to ±12 A
• **Voltage Mode Output Impedance:** 60 µΩ (dynamic)
• **Current Mode Output Impedance:** 50 µH (dynamic)
• **Bandwidth (Voltage Mode):** 20 kHz
• **Rise/Fall Time:** 16 µS

## Key Features
• Four-quadrant operation with independent voltage and current control circuits and automatic crossover to limits
• Zeroable preamplifier for external signal scaling and summing
• Dynamic performance in voltage mode; reduced bandwidth and increased rise/fall times in current mode with resistive loads
• Stability optimized via feedback capacitance adjustment for loads exceeding 0.1 µF
• Special user-port terminals enable inductive-load compensation; modified versions (BOP 36-12ML/DL) support inductive loads up to 1 Henry
## Typical Applications
• Dynamic transducer and actuator control
• Real-time signal amplification and waveform replication
