A. Overview

This  equipment introduced  Germany  dual  system educational  mode”  to  meet the

request of  vocational education and  practical operation training.  Under the guide  of

Chinese people  who had  been studied  abroad, introducing and  absorbing advanced

vocational training  equipment overseas and  producing products which most  close to

the  electrical  and  electric  drive equipment  at  industrial  scene  according  to  DIN

standard didactic equipment.

“DLWD-ETBE Electrical  Technology  Know-how Training  Series”,  with operation

safety (multiple human and equipment safety protection), is normative, flexible, stable,

durable  with beautiful  appearance  which  is  full of  sense  of  modernization. With

special working material and scientific structure, beautiful appearance,   the surface is

covered

by sapphire blue  painting and

it

together with the  patch board, power

box,  table board  and cabinet  have become  the mainstream  of  today’s science  and

technology——“silver blue world”( color blue and silver is the representative color of

science and technology).

“DLWD-ETBE Electrical Technology Know-how Training Series” are modern signal

products of school training  room. This set is  also the top choice of “Theory  practice

teaching”,  “Curriculum   teaching”,   “Modular  teaching”   and  “Project   teaching”

promoted by school.

B.Feature

1.Training platform and cabinet

The  flat  form  is  blue  column  structure  with  regulator  on  desk  lag  and  height

adjustable  to  assure  platform  stable. The  desk  is  fire-proof  material.  Fire-proof,

anti-abrasion, anti-light,  stain  resistant, strike  plate,  heat proof,  waterproof,easy  to

clean and high color fastness.

2. Power box

a) Aluminum structure, beautiful appearance. Complete with ETBE series.

b) Simulating instrument panel identity. Students easy to know the instruments

c) Heavy line framework distinguish function unit. Easy to operate,safety.

d) Supply box supply three-phase,  five wire power, single-phase power and two way

current 0-30V adjustable power. Protection for over current, low voltage, short circuit

and leakage. Four DC current/power meter outfit. The components are imported from

famous manufacturers. With scram button.

3. Patch board

Advantages:

To professional development and extension, and not be restricted equipment

Avoid repeat input, reduce equipment investment

Close to industry scene（patch board is widely use）

d) Student can design. Easy to cultivate students' creation

e) Easy to exercise the student operation ability

The stainless plate we use  is imported from Germany. Punching  is according to DIN

standard. The  CNC machine is  imported from Japan.  Special model is  Wilson. The

tolerance of hole is  about 1um.The dimension of patch board is 640*730mm  is fit to

DIN standard. This can assure various components fixed on any place.

This is used for training electrical skills, installation tectonics, fault analysis. Also can

be used  for assessment and  testing of electrical  and electric. The  experiment circuit

can  be   simple   and  multiply   as   required.  General   lighting  circuit,   automatic

closed-loop  control regulator  and  trial automation  systems  and integration  can  be

installed on the patch board. The patch boards have long life for more than 10 years.
