Key Features:
Multiple Operation Modes: Constant Current (CC), Constant Resistance (CR), Constant Voltage (CV), Constant Power (CP), CC+CV, CP+CV, dynamic, and short-circuit modes.
Battery and BMS Testing: Includes built-in test modes for battery discharge capacity and protection testing for lithium battery BMS.
Turbo Mode: Allows for overload testing by doubling the power and current within 2 seconds, ideal for testing fuses, breakers, and BMS systems.
High Slew Rate: Up to 10A/μS (depending on model), suitable for simulating rapid transient responses.
Parallel Operation: Allows combining multiple units for increased load capacity in CC, CR, CV, and CP modes.
Advanced LCD Display: Displays 5 digital values (V, A, W) simultaneously.
MPPT Support: Test function for maximum power point tracking on solar panels.
