Specification

Characteristic;
1.SA-Series Switch-mode Power Amplifiers is designed specially for driving electrodynamic vibrators. It consists of excitation DC power supply, fan cooling power supply and horizontal slipway oil pump power supply.
2.SA-Series Switch-mode Power Amplifiers is designed modularly and easy to combine with all vibrators made by different factories.
3.The frequency of the switch is 150 kHz. We reduce the size of the wave filter inductance elements so that lighten the weight of the power amplifiers. The power amplifiers are efficient and with low distortion of the wave shape.
4.SA-Series Switch Power Amplifiers has many mutual signal locks for protection and linkage:
a: electro-breaker switch,
b: shaker over-displacement, over heated, water leaking, heat exchanger
c: power amplifier over heated, over voltage, over electricity
d: over loading of fan and oil pump
5.EMI protecting box and cable
