High-voltage O/P Power Supply For Portable Ultrasonic Devices


MORNSUN has launched a high-voltage output power supply, the HO1 series, designed for applications of portable devices with ultrasonic technology. These include ultrasonoscope, pile test instrument, ultrasonic thickness gauge, non-metallic ultrasonic testing detector for concrete, and electrostatic printing, high voltage bias, industrial control, medical chemical industry, scientific experiment and so on.

The power supply features a 12V fixed input voltage and 0-600V continuous output with linear adjustable function. Adjustable output voltages of 200-1200V (0-200V, 0-600V, 0-800V, 0-1000V, 0-1200V optional) are available depending on different requirements.

The new HO1 series offers 600V high voltage to power ultrasonic detector, forms high voltage pulse at probe chip by drive circuit and results in pulsed ultrasound for high-frequency mechanical oscillation after electro-acoustic conversion.


The series has a wide operating temperature range of 40°C to +85°C without any derating, making it highly reliable.

Temperature coefficient of the new series is ≤ ±0.01%/℃, time coefficient is ≤ ±0.05%/hour, and output ripple is as low as 15mVp-p (typ.);

The output is stable and does not deviate with environmental changes, making portable devices testing results more accurate, claims Morsun.

The power supply is said to offer excellent EMC performance, better compatible system design, less electromagnetic interference to sensitive acquisition circuit, and more sensitive and accurate measurements.

In addition, HO1 series also has output short circuit and over-current protections to meet specific environment applications such as ultrasonoscope, photomultiplier tubes (PMTs), avalanche photodiodes, etc.
