I need a 12V automotive AC Compressor for an electric vehicle. Is this the right product? I read 312V and I don´t understand if it´s 12V or 312V.Please advise if this compressor is suitable for a regular electric conversion car using it´s energy from a 12V battery.Do I need any other components to make it work? a PWM signal maybe? Please let me know.Thank you and best regards,Maurice Claux
