PM 0043

  • 4ch IEPE,3ch AMP

  • PM 0043 is a conditioner specifically designed for production line testing of consumer products. It features a 4-channel 23V constant-voltage exciter, which is used to condition IEPE-powered sensors such as microphones, artificial ears, and accelerometers. Additionally, it has a 3-channel power amplifier for driving high-power loads like artificial mouths and speakers. When used in conjunction with the IMP 1000, it can also perform speaker impedance analysis.

    This product is characterized by its abundant channel resources, adjustable IEPE gain, high input impedance, low output impedance, low noise floor, wide frequency response, and high test repeatability.
