1. Circuit of teacher control console

Touching type of CMOS integrate circuit

LED screen displays voltage value.

Main AC/DC power supply of this laboratory is controlled by teacher with drawer model.

AC 220V power supply with leakage protection function

Adjustable voltage-stabilized DC2V-DC24V, Adjustable voltage-stabilized low voltage AC2V-AC24V, High power DC9V, High power DC24V, High voltage DC240V, High voltage DC300V are all with fine adjust function.

Four independent switches to control four groups (A, B, C, D) of students AC220V power supply

2. Circuit of student experiment table

Adjustable DC2V-DC24V power supply, and can be controlled by student or teacher control console

Adjustable voltage-stabilized DC2V-DC24V, Adjustable voltage-stabilized low voltage AC2V-AC24V, and AC220V are controlled by teacher control console, and then transmits to student experiment table after pre-adjusting.

DC2V-24V and AC2V-24V can be controlled between teacher control console and student experiment table.

Measuring tools come standard, include DC voltage meter, DC current meter and micro-current meter, and can test DC voltage, DC current and micro-current. This is very convenient to test external experiment circuit.

3. Wood part

Medium Density Melamine Plywood

Manufactured by German woodworking machinery with fine manufacturing technology
