Need a variable speed drive? Whether you have a 3 phase (415v) supply or a domestic single phase (230v) supply, one of our Goldcrest inverters should provide you with the motor speed range that you require. You can order your inverter for either 230v or 415v input, but remember the motor you order with it will always be a three phase (which is cheaper anyway) Just ring me (Tony) on 01785 818338 or 07940 872475 for advice 8.30am - 5.00pm Monday - Friday, or send me your enquiry via eBay.
