The 8600 series programmable DC electronic load has specialized modes for unique applications. The built-in battery test mode measures ampere-hours (Ah), voltage, and capacity level. CR-LED mode simulates the loading behavior of a typical LED. Power supply test modes validate overcurrent and overpower protection functions. Constant current, voltage, resistance, and power modes can be configured for a dynamically changing load with fast switching times. Self-test mode ensures reliability.
