Kepco BOP200-1M

The Kepco BOP200-1M is a 200-watt bipolar operational power supply delivering precision voltage and current control across four quadrants. Operating as both a stable DC source and amplifier, It has smooth linear control from negative to positive voltage and current ranges without polarity switching. This high-speed power operational amplifier excels in applications demanding dynamic, linear regulation - including resistive loads and precision test systems. Unlike general-purpose supplies, the BOP200-1M omits energy-storage output capacitors to minimize high-frequency noise, making it ideal for fast-transient applications. Capacitive loads exceeding 0.1 µF require operational slowdown to prevent oscillation.
