High-Voltage Power-Supply Module for Ultrasonic Transmitter
specially designed for ultrasonic electronic equipment working in the harsh environment, is portable with its size of only L38.0×W22.0×H8.5mm and saves space for portable ultrasonic instrument. In consideration of battery-power supply characteristics of portable ultrasonic instrument, the power-supply module is designed with static working current of 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 105℃. 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
