Digital Switch Type Amplifier Introduction:

This system adopts the sine pulse width modulation technology of digital power amplifier.Its working

principle Is:using the MOSFET field-effect’s high frequency switch power, through digital circuit to amplify and restore the low-voltage signal which input by controller, Then the output the original signal to vibration

tester's moving coil circuit,and drive vibration tester's extension table movement.The main part of the digital power amplifier: the front control, power amplifier module, protection circuit, the power part and electric cabinet.

Digital Switch Type Amplifier Features:

1.Easy maintenance: Interchangeable power module box, compact design, saving space, easy to

maintenance.

2.LCD display:

Logic module adopts microcomputer CPU chip processor, LCD display function;Can be showed

various system data in detail (The power amplify output True RMS value, with additional data

display) and operation state and fault judgment.With remote control, remote measuring, remote

communication function, friendly interface, easy operation.

Digital Switch Type Amplifier Protection function:

The power amplifier set up protection of power grid over-voltage, power grid under-voltage, power

grid lack of phase, logic fault, power module, power temperature module,output over-current, output

over-voltage,driving power, the table’s displacement, table temperature, etc. Any failure occurs, shut

down output,with sound and lighting alarm at the same time. Except the above protection, also has poor

RMS value the protection, and emergency stop protection.

High conversion efficiency ( higher than 92%) ,and high convert ion frequency

Horizontal Slip Table:

With horizontal slip table ,the electrodynamic vibration tester able for X,Y,Z trial direction testing.And can combine temperature humidity test system do combined environmental testing .With turbo - scroll bar or chain wheel rotation system, one person can easily rotate the vibration bench and connect it to the horizontal table.Adopt mechanical position limitation to ensure the connection between the vibration system and horizontal slip table. Multi size slip table available, from 300mm×300mm(for small vibration system)to large specimen test 2m×2m slip table. Different bearing limitation able to perform different operation and comply different requirements. The thickness and size of the slip table will influence the vibration system performance, and affect the high limitation frequency , user can customize it.

Digital Controller Features

Vibration controller is the latest design by ucon company that adopts international advanced distributed system architecture, and its core is the latest TMS320 series 32-bit floating-point high-speed processor of TI company. Test report is automatically generated in Microsoft Word. During or after the testing, the test report can be edited, and then generated automatically or manually.
