Built-in 3.7V lithium battery with a robust capacity of 1500mAh ensures extended usage, ranging from 1-5 hours depending on the output load. It features a maximum charging current of 0.8A, with a battery indicator that turns green upon full charge, automatically halting the charging process, typically taking over 6 hours. Voltage output settings are highly customizable within a range of ±12V, with a factory default of 0-10V. Post-calibration accuracy reaches up to 0.03V, ensuring precise measurements. Additionally, the unit is equipped with reliable short circuit protection for enhanced safety. Current output can be finely adjusted from 0-24mA, with a preset range of 4-20mA as the factory default. After calibration, the accuracy sharpens to 0.05mA, and it supports a take-off resistance of less than 500 ohms, including the capability to handle short-circuits effectively. Features a versatile PWM output with a frequency range adjustable from 1-150 kHz and a duty cycle that can be set from 0-100%. The high level is fixed at 5V, suitable for driving currents under 20 mA. Note: This PWM output is not suitable for 12V or 2V systems as 5V is considered a low level for these configurations. Designed to remember the output value even when powered off, this generator ensures continuity in operations. It includes comprehensive safety features such as output short circuit protection, reverse connection protection, and charging protection, making it a reliable tool for various applications.
