Hi folks
I'm currently building a restaurant and commercial kitchen. The extraction system uses a fan with a 3 phase motor. I've measured the voltage at around 110/120v per phase and my clamp meter shows a draw of around 1.5 amps per phase under full load. I'm looking to build/buy a speed controller but cannot seem to find many (affordable) options. I understand I can either adjust frequency or voltage. Hoping someone can push me in the right direction of what I should be looking for. Thanks in advance
