The BCS6402 battery charger/simulator and precision DC power supply is optimized for testing batteries and battery-operated devices. The BCS6402 features source/sink capabilities, a bipolar output, and variable output impedance to charge, discharge, or simulate batteries used in portable and wearable electronic devices. The BCS6402 also serves as a precision DC power supply with exceptional transient response times, high current readback resolution, and low ripple/noise characteristics due to its linear design. To handle rapid load changes, the fast output speed setting optimizes transient response time while minimizing overshoot and output recovery time. The BCS6402 single channel model offers up to 150 W of output power.
