Low voltage input and high current with high slew rate of 100a/us electronic loads introduced by texio corporation [formerly kenwood] japan, can be run with minimum operating voltage of 0.3 v with rating current of 150 a. Equipped with each is a discharging mode, constant current, constant resistance, constant power and constant voltage. Confirmation of setting conditions can be made easily on the lcd panel and with joystick operation. For external control gp-ib, usb, and rs 232c interface are equipped as standard, and all settings can be performed through a pc. These electronic loads find wide applications in evaluation and testing of microprocessors pol and vrm power supplies, power supply circuits, batteries, including fuel cells, and electronics components.
