Advanced Electrotechnics Maintenance Skill

Training& Assessment System

A Overview

This device uses hanging box-type structure. The hanging box panel is equipped

with AC contactor,time relay,button,switch,thermal relay,PLC and other

experimental component.

B Feature

1. All the components of electrical  control circuit and electric  circuit are installed on

the panel.  Easy to  operate and replace.  Extended function  and develop  training

with topic and practicability option.

2.  Three phases,  five  wires input  to  assure  the training  equipment  grounded  and

stable.

3. Heavy line frame to distinguish function unit, Easy and safe.

4. Multi-protection on the meter box to avoid damage on the meters.

5. Special design for control  wiring and motor can simulate all electric  drive system.

Also it can meet requirements of installation, debug, fault analysis and so on.

6. With  current  against leakage  protector  to assure  the safety  of  operator. All  the

power output have monitor and  short circuit protection. All measurement  meter have

protection and the control screen have timer and alarm.

7.  All  the  components lead  to  terminal.  Student  only  need  to  connect  wire  on

terminals to protect the components.

8.  Platform  is  aluminum.   The  desktop  is  anti-fire,   water  proof  with  beautiful

appearance.
