Precise, timed switching sequences (like an automation relay for a testing cycle or dosing system).
The is a highly versatile, dual-mode electrical signal generator capable of driving high-current loads up to 8A directly. Operating on a wide DC voltage range of 3.3V to 30V, this device serves as a square-wave signal source, motor speed controller, valve actuator, and test bench excitation source.
: Provides continuous frequency control (1Hz to 150KHz) and duty cycle adjustment (0–100%) for tasks like motor speed regulation or LED dimming. PULSE Mode Zk-pp2k Manual
: By connecting a therapeutic coil to the ZK-PP2K and setting the module to output low-frequency pulses (4-30 Hz) with a 5-15% duty cycle, you can create a simple PEMF device. This involves connecting a 12V-19V power supply (e.g., a laptop charger) and a hand-wound coil with sufficient resistance to form the core of the therapy system.
Shows frequency, duty cycle, or pulse settings. Rotary Encoder: Dial to increase or decrease values. On/Off Button: Toggles the signal output instantly. Mode Switch: Internal setting to toggle PWM or Pulse mode. Wiring Terminals: VIN+ / VIN- : Power supply input. PWM : Signal output terminal. GND : Common ground terminal. ⚙️ Operating Modes Explained The device operates in two distinct functional modes. 1. PWM Mode (Continuous Output) Precise, timed switching sequences (like an automation relay
PULSE mode gives you fine control over individual pulse waveforms, down to the millisecond. Hold for 6 seconds until the "%" icon clears.
"Because," Kael said, "it was designed by sadists. It requires a specific sequence to arm the firing pin. If you get it wrong, the chamber seals shut. Forever." : Provides continuous frequency control (1Hz to 150KHz)
Now, a pile of suspiciously gun-shaped metal sat in a tray, mocking him.
The ZK-PP2K is controlled via four tactile buttons on its front panel. A basic understanding of these buttons is essential for using the module effectively. The table below provides a quick reference.
