Switching Power Amplifier

SA Series switching power amplifier has the newest MOSFET technology, output power is from 5 kVA to 500 kVA, and all series are air-cooled.
SA Series switching power amplifier has high reliability, balancing parallel current, large output margin and can meet the requirements of 3σ of random vibration.
  • Designed for electro-dynamic vibrator, the power amplifier includes the power supply of filed coil, blower and oil pump of slip table. Modular design, convenience combination, and can match any shakers from other manufacturers.
  • Switching frequency up to 100 kHz and above. Higher switching frequency will reduce the size of filter component and the weight of amplifier, makes the amplifiers more reliable, and has small waveform distortion.
  • True color LCD and control methods. The LED shows output current and voltage, system working status and protection indication. New dust-proof design, the interior is compact with good appearance.
  • Variety of protection and the linkage signal interlock
a)Leakage circuit breaker switch
b)Shaker over-displacement, overheating, leakage, heat exchangers
c)Amplifier overheating, over-voltage, over-current
d)Fan and pump overload

STI is a world-famous production reliability test solution provider with 50 years experience in the industry.
