Specifications

ELECTRO-DYNAMIC SHAKER
ELECTRODYNAMIC SHAKER


FUNCTIONAL FEATURES--ELECTRO-DYNAMIC SHAKER

Double magnetic circuit structure to ensure high magnetic field intensity & reduce flux leakage; Special degaussing structure can
Reduce flux leakage to below 1 mt;

U-type spring,rollers and linear bearing for strong resistance of deflecting load;

Air spring are used for vibration isolation; Vibration system work steadily even with heavy load; no need special foundation;

Protection devices are provided for over-thermal, over-load, over-current, over-voltage, and over-displacement of the vibration
Tester; Electrical network protection devices for over-voltage, under-voltage, lacking phase; Drive power, current-limiting, soft-start,
over-temperature, short-current,module fault protecting;

Able to complete sine,random, impact environmental tests;

this system requires voltage fluctuation, 10%;

this system requires Grounding resistance, 4;

High reliability, especially suitable for long-time operation;

AMPLIFIER---ELECTRO-DYNAMIC SHAKER

GENERAL INTRODUCTION---ELECTRO-DYNAMIC SHAKER

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.

FUNCTIONAL FEATURES---ELECTRO-DYNAMIC SHAKER

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.

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

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 displayand operation state and fault judgment. with remote
Control, remote measuring, remote communication function, friendly interface, easy operation.

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 conversion frequency.
