HS Series High-voltage Power Supply Modules Charact e rized with Low Po wer Consump tion
Description:
With a breakthrough in the development of components due to the increasing scale and the close
cooperation with some foreign high-temperature component manufacturers, VAW Electronics Co, LTD embarks
on initiative design and customization of specialized high temperature electronic components. Based on more than
a decade of R & D and production, the company's electronic engineers have designed and customized a series of
dedicated power components which are charactered with wide operating temperature (-55℃～+150℃, -55℃～
+175℃, -55℃～+200℃, -65℃～+250℃) and various types (175℃ high-voltage lead capacitor, 350℃
magnetic core, 600℃ magnetic core, 250℃ SMD induct or, 250 ℃ SMD current sampler, 250℃ current sample
operational amplifier, 250℃ SMD capacitor, 250℃ SMD Precision high-power resistor, 250℃ SMD discharge
protector, 250℃ dedicated power control chip, 250℃ high-capacity filter capacitor, 250℃ high-power fast
switching tube, 250℃ high-current fleetness rectifier tube). In addition to using the most advanced special
components, HS series of high temperature and high voltage power modules also employs a number of
components developed and customized based on proprietary intellectual property rights, and produced according
to the technology and production quality control system of military supplies. The performance of all the products
has reached a new standard. All products in this series can work under -40℃ +225℃ ambient temperature
for 4 hours without considering their reliability.
Scope of application ：petroleum survey logging tool,petroleum drilling instrument,geophysical detecting
instrument, vehic les, tel ec o mmunication, network infrastructures, ent e rprise and hi g h-performance calculation.

3 Service Requirements：
（一） The ambient temperature shall not be higher than the maximum operating temperature of the module for a
long time. The module can work reliably in the rated temperature range without thermal damage for a
long time and, the maximum experimental time of the continuous work is 200 hours. However, the
working environment temperature higher than the rated operating temperature can accelerate
damage and aging of the devices and material, doubling the probability of failure. According to t en
years of statistics for the HVC series, the reliability data obtained are as follows: (there is no statistical
data for HS series temporarily because of their just being launched )
(1) In the rated temperature range, there is no limit on working hours and, the accidental failure period is
more than three years and, the constant failure rate (CFR) is less than 1%.
(2) Beyond +25℃ of the rated working temperature range for two hours each time, the failure rate is less
than 1 percent in the first year, about five percent in the second year, and about 10 percent in the third year.
(3) Beyond +50℃ of the rated working temperature range for two hours each time, the failure rate is less
than10 percent in the first year, about fifty percent in the second year, and about seventy percent in the
third year.
（二） Output voltage shall facilitate the installation of connection, in some occasions, if the output voltage and
input power are connected to the line where there may be interference, input power shall be shared.
（三） To make high-voltage output ripple less in use, the accompanying resistance and high-voltage capacitor
provided by our company can be used to form a RC filter, and the ripple generally could be less than 1
mVp-p. See the attached figure for connection method.
（四） When a voltage control mode is applied to high-voltage negative supply, a resistor shall be connected in
series with the green pilot wire, whose resistance value is exactly the value of the high-voltage output
change beginning from zero volt when the resistor is under the control mode, then the high voltage output
conforms to the curve of electric diagram.
