[Signal Generator Parameters] Wide operating voltage: DC 3.3V-30V; Output current: 8A (maximum); Frequency range: 1Hz-150kHz; Duty cycle range: 0.00%-100% (Note: Do not reverse the signal generator's positive and negative poles, as this may cause damage). [Dual Mode] - PP2K PWM DC Motor Speed Regulator has two modes: PWM mode: adjust frequency and duty cycle (Note: number of switches cannot be set in this mode); PULSE mode: set startup delay and start time, with adjustable number of switches. [Can Directly Drive Loads] Capable of directly driving loads such as LEDs, motors, and solenoid valves. Pulse count, frequency, duty cycle, and delay period are adjustable. [Usage] Can control the on/off function of equipment and is suitable for switch fatigue testing. Power-off testing to verify equipment reliability. Applicable for use as a PWM signal generator; for driving lights, motors, solenoid valves; square wave or rectangular wave signal generation; and control of servo motors, stepper motors, and electric grippers.
