Frequently Asked Questions
Q: What is a three-phase sine signal generator used for?
A: A three-phase sine signal generator is used to simulate or test three-phase AC signals in electronics development, motor control systems, inverter testing, power electronics research, and circuit simulation. The Elubor generator allows precise independent adjustment of frequency (0.1–2000 Hz) and phase (0–360°) for each of three output channels.
Q: What is the difference between sine wave output (filter ON) and PWM output (filter OFF)?
A: When the built-in filter is enabled (Filter = ON), a filtering capacitor is connected to the output, producing a smooth sine wave signal. When the filter is disabled (Filter = OFF), the device outputs a PWM (Pulse Width Modulation) signal without the capacitor. Choose the mode based on your application requirements.
Q: What power supply does this signal generator require?
A: The Elubor three-phase sine signal generator operates on a DC power supply between 7 V and 12 V, drawing less than 50 mA of current. Batteries are not included. A regulated DC bench power supply or suitable DC adapter is recommended.
Q: Can this device measure external signal frequencies as well as generate them?
A: Yes. In addition to generating three-phase sine signals, this device includes a built-in frequency measurement function that can measure external signals from 1 Hz up to 200 kHz with a resolution of 0.01 Hz. The input voltage range for frequency measurement is ±0.7 V to 10 VDC.
Q: Is this generator compatible with standard microcontroller or embedded system projects?
A: Yes. With a 5 Vpp output amplitude and a standard LCD1602 display interface, this generator is well-suited for integration with microcontroller-based projects, embedded system testing, and lab bench setups requiring precise three-phase signal sources.
