PWM Signal Generator Dual Channel 1Hz-150kHz Panel Mount DC 5-24V PWM150

🔧 PWM150 Dual Channel Panel Mount PWM Signal Generator | AuscomTech

The PWM150 is a panel mount dual-channel PWM signal generator designed for precise square wave and pulse signal generation in electronics testing, control systems, automation and DIY projects. With an adjustable frequency range of 1Hz to 150kHz, independent output channels and fine duty cycle adjustment, it provides flexible signal control in a convenient integrated panel-mounted format.

Operating from a DC 5–24V power supply, this digital pulse generator features a rotary encoder, dual LED numerical displays and dedicated control buttons for adjusting frequency, duty cycle and phase. Two independently configurable channels can also operate in synchronised mode for applications requiring coordinated PWM signals.

Ideal for installation in custom control panels, electronics test benches, automation enclosures and equipment prototypes, the PWM150 provides a practical standalone alternative to microcontroller-based signal generation where direct manual adjustment is preferred.
