Tenders Description & Specification for Experimental Panel Industrial Installations (Contactors and Switches) Teaching Equipment
Experimental Panel Industrial Installations (Contactors and Switches) Teaching Equipment
This Panel, complete with switches and electromagnetic devices, is the main unit for the practical learning of cabled direct and sequenced starting of single and 3-ph AC motors.
The panel, made of insulation material, includes the international symbols of all the devices. The connections are done in an easy and fast way via cables (supplied) with 4 mm safety terminals.
Not any tool is required for the development of the exercises. To perform the exercises in a “realistic” way, different types of AC motors and starting devices are supplied.
The control (or command) circuits work with 24 VAC ; the power circuits work with mains at 230 or 400 V; both power supplies are independent and protected with automatic thermomagnetic switches. This design allow to test fi rst the command circuit, and later the power circuits.
The panel can be used in different positions over the table, according to the client requirements of service and room.
