- N35100 series is a bidirectional programmable DC power supply. N35100 adopts dual quadrant design, which can supply &absorb the power, and return power to the grid cleanly, so as to save the power consumption and reduce the space heat dissipation, which can greatly reduce the test cost. N35100 series provides high precision measurement and multiple testing functions, which can be widely used in new energy, automotive, energy storage, electric drive, battery simulation and other industries.
