2-quadrant battery charger/simulator and power supply series
B&K Precision has announced the release of the BCS Series battery charger/simulator, optimised for testing batteries and battery-operated devices.
Consisting of a single and dual channel model in a compact 2U form factor, this series features source/sink capabilities, a bipolar output, and variable output impedance. Additionally, this series serves as a precision DC power supply with exceptional transient response times, high current readback resolution, and low ripple/noise characteristics.
The single channel model delivers up to 150W of output power while the dual channel model offers up to 45W per channel or 90W combined. Device manufacturers and design engineers typically evaluate their products under various battery conditions including different capacity and internal resistance levels.
Battery simulation mode allows users to configure battery parameters including capacity, voltage, and internal resistance to evaluate a device under test. This reduces the need for a physical battery where parameters may not be as easily controlled. In addition to battery simulation, these instruments feature comprehensive battery charge and discharge capabilities with configurable stop conditions.
When enabled, the relay off function offers electrical isolation from connected batteries to prevent parasitic drain. Both models also provide list mode programming, internal storage for custom battery simulation profiles, and a rear panel digital voltmeter (DVM). Remote PC interfaces include USB (USBTMC-compliant) and LAN interfaces supporting SCPI commands.
