It also features built-in anti-reverse polarity protection. The PP2K uses a high-power MOS transistor switch output rated up to 8 A, so it can directly drive DC motors, LEDs, and solenoid valves without a separate driver. Both modules share the same dual-mode (PWM + PULSE) functionality and the same frequency\/duty cycle range.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I switch between PWM mode and PULSE mode on the module?\u003c\/h4\u003e\n\u003cp\u003eA: The module powers on in PWM mode by default (a \"%\" symbol is shown on the LCD). To switch to PULSE mode, press and hold the SET button for more than 6 seconds until the \"%\" symbol disappears from the display. To switch back, repeat the long-press. All parameters are stored in non-volatile memory, so your settings are preserved after power-off.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I set a timed delay before the output starts?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. In PULSE mode, press and hold the SET button for approximately 2 seconds to enter the pulse count and delay time settings interface. Use the P+\/P− buttons to set the delay time (0.000 s up to 9999 s, with 1 ms resolution) and the N+\/N− buttons to set the number of output pulses (1–9999 or infinite). Press SET again to return to the main pulse interface, then press ON to begin — the module will wait the specified delay before emitting pulses.\u003c\/p\u003e\n\u003ch4\u003eQ: What input voltage range is supported, and is reverse polarity protection included?\u003c\/h4\u003e\n\u003cp\u003eA: Both modules support a wide input voltage range of 3.3 V to 30 V, making them compatible with common power supplies including 5 V, 12 V, and 24 V systems. The PP1K includes built-in anti-reverse polarity protection. The PP2K does not include this protection, so ensure correct polarity before connecting power to avoid damage.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the maximum frequency this PWM generator can output?\u003c\/h4\u003e\n\u003cp\u003eA: Both the PP1K and PP2K support a frequency range of 1 Hz up to 150 kHz. The PP1K has approximately ±1% frequency accuracy; the PP2K is approximately ±2%. For DC motor speed control applications, a frequency of 20 kHz is typically recommended to keep switching noise outside the audible range.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the difference between the PP1K and PP2K PWM signal generator modules?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The PP1K outputs a low-power signal (up to 30 mA) intended to drive external motor driver boards, stepper motor controllers, servo amplifiers, or other signal-level inputs.
