The dual voltage, isolated VFD?PCM inverter can accept a speed reference signal without a separate isolation card. They can be used with a variety of motors including 3?phase induction, single?phase permanent split capacitor (PSC),shaded pole and synchronous motors. Packed with features, the VFD?PCM series has a 'doubling' jumper that can be set to output 230VAC to a motor when only 115VAC power supply is available. A jumper also determines if the VFD is set for automatic or manual restarting.
