PLS500 Dual-Channel PWM Signal Generator 1Hz–500kHz DC 5–24V
PLS500 Dual-Channel PWM Signal Generator 1Hz–500kHz DC 5–24V
PLS500 Dual-Channel Pulse PWM Signal Generator
The Gaqqee PLS500 is a professional-grade, programmable dual-channel PWM signal generator designed for engineers, electronics hobbyists, and lab technicians who demand precision and flexibility. With a wide frequency range of 1Hz to 500kHz, a full 0–100% adjustable duty cycle, and complementary output with programmable dead time, this compact unit handles everything from basic switching tests to complex industrial servo simulations.
Key Features
- 1.8-inch Colour Display — Clear, vibrant screen with intuitive encoder + pushbutton operation for fast, accurate parameter adjustments.
- Wide Frequency Range: 1Hz to 500kHz with 1Hz step resolution — ideal for sweep frequency testing and fine-tuning.
- Dual-Channel Output (CH1 + CH2) — Independent or complementary channel operation with phase shift testing support up to 359°.
- Duty Cycle Control: Freely adjustable from 0–100% with 0.1% step resolution; no waveform distortion at full pull-up or pull-down.
- Complementary PWM with Dead Time: Programmable dead time from 00–91ns (7ns increments) or 00.0–20.0µs (0.1µs increments) — perfect for H-bridge and motor driver testing.
- Ultra-Fast 10ns Rise Time — Maintains pristine waveforms even at high frequencies for accurate driver and switching device testing.
- Programmable Pulse Timing: T0 delay, T1 positive pulse width, and T2 negative pulse width each configurable from 0.001s to 60.000s.
- Pulse Count Control: Set counts from 1 to 60,000 or run continuously (∞).
- CE & RoHS Certified — Meets European safety and environmental standards.
- Compact Form Factor: 108×63×24mm panel-mount design with 100×56mm cutout dimensions.
