Battery Simulating DC Power Supplies

Optimized for portable, battery-operated devices
Testing portable, battery-operated devices under realistic conditions requires a DC power supply that can simulate a battery under a wide range of situations. Keithley's battery simulating power supplies can simulate both a battery's output resistance and discharge state. The dual-channel version of these power supplies can use one channel to sink current for simulating a discharged rechargeable battery while using the other channel to supply voltage for testing the charge control circuitry of a portable device.
