AZE4121 Experimental Panel Industrial Installations Vocational Training Tools And Equipment Electrical Lab Equipment
INTRODUCTION
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 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, 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 panel can be used in different positions over the table, according to the client requirements of service and room.
