The PT570P and the PT570-24P are medium duty outdoor pan/tilts capable of handling loads up to 40 pounds (18.14 kg). Both units feature rugged worm-gear final drives to minimize backlash and prevent wind drift. The drives are fully adjustable for wear. Control voltages are 120 VAC for the PT570P and 24 VAC for the PT570-24P. Construction is of aluminum, and the units are completely sealed for all-weather use. The PT570P and PT570-24P are recommended for use with our EH4700 Series environmental enclosures. An optional factory installed heater is available to allow operation to -50°F (-45°C).
