specially designed for oil prospecting acoustic logging tool working in the harsh environment, is only L38.0×W22.0×H8.5mm in size and saves space for acoustic logging tool. Simply designed, the power-supply module’s static working current is only 30mA and load conversion efficiency up to 80%. It is resistant to high temperature, shock and moisture when working in harsh environment, thus it is able to normally work at an ambient temperature of 175℃. Shock resistance frequency: 20-50Hz/50Hz-2KHz and amplitude/rate: 0.5mm/10g. Shock resistance reaches three times per amplitude. Spike rate: 100g and duration: 6ms
