The BCS Series battery charger/simulator and precision DC Power supplies are optimized for testing batteries and battery-operated devices. This series features source/sink capabilities, a bipolar output, and a variable output impedance with dedicated battery charge, discharge, and simulation modes. Additionally, both models serve as a precise single channel or dual channel DC power supply with fast transient response and low ripple/noise characteristics.

Applications include evaluating batteries and charger circuitry used in cell phones, wearable devices, and other IoT devices.
