170w Power and White Color projector lift

Buy offer Details

Dear Friend,
I am starting an audiovisual company in Per (South America). I am looking for projector lifts for 10 kilos of loading weight and 3 travel options : 0.75, 1 and 1.5 meters. The voltage in my country is 220VAC, 60Hz. Free space in false ceiling is common of 0.45 meters, I could consider other similar measures. The option of control must be by RF and contact of 5, 12 or 24VDC. (for control systems). You could send me a quotation of 3 units, one of each model. It is the first time that I will do business with China and I need to make a portfolio of suppliers. Also, would you appreciate, for your experience, recommending the best purchase option?
Best regards,
Johann Miranda.
