Description:
FP series high-voltage power-supply module is specially designed for laser radar device working in the harsh environment.
It is a power supply system especially applicable to petroleum survey logging tool,petroleum drilling instrument,geophysical
detecting instrument, vehicles, telecommunication, network infrastructures, enterprise and high-performance calculation.
FP series power-supply module is portable with its size of only L33.0×W22.0×H8.5mm and saves space for portable laser
radar. Simply designed, its static working current is only 10mA and load conversion efficiency up to 80%. This is suitable to
power supply characteristics of battery of portable device. 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
FP series power-supply module has five selections for input range and given rated voltage is its central value in working.
When input voltage is equal to rated input voltage, conversion efficiency of power supply reaches maximum. When it deviates
from rated value, the module is also able to work normally, but its conversion efficiency is low. Considering that its power
source may be not steady, it allows several input ranges including +5V(4.5～9V), +12V(7.5～15V), +15V(10～20), +24V
(15～30V) , and +28V(18～36V). Within the entire range of working temperature and conversion between full load and
no-load, and when input voltage fluctuates from minimum voltage to maximum voltage, output voltage fluctuates within 0.3V.
Output high voltage of FP series power-supply module is continuously adjustable from zero to the highest and there are
voltage-control type and resistance-control type. Control voltage ground and input ground of voltage-control type are
connected. When the range of control voltage applied to control end (ADJ) is 0～5.0V, output high voltage has linear variation
with control voltage. When control voltage is 0V, output high voltage reaches the minimum value and when control voltage is
5.0V, output high voltage reaches the maximum value. When control voltage is higher than 5.0V, output high voltage still has
linear variation with control voltage, but its performance and reliability will reduce sharply, for this reason, control voltage
should be less than 5.5V.
For FP series, control resistance of resistance-control type is connected between adjustment control end (ADJ) and input
ground and output high voltage increases with increment of control resistance, but not in linear. The more the control
resistance is larger, gentler the high voltage changes with it. When control resistance is infinite, namely control end is
suspended, output high voltage reaches its maximum value. Normally it is ok to connect a 200K adjustable resistance.
Resistance-control type can also use voltage to control output high voltage. First connect a resistance in series at control end

and apply control voltage. The bigger the resistance is connected, the higher the minimum output voltage will be! When the
range of control voltage is 0～5.0V, output high voltage has linear variation with control voltage. When control voltage is 0V,
output high voltage reaches the minimum value and when control voltage is 5.0V, output high voltage reaches the maximum
value. When control voltage is higher than 5.0V, output high voltage still has linear variation with control voltage, but its
performance and reliability will reduce sharply, for this reason, control voltage should be less than 5.5V. Its difference with
voltage-control type is that its minimum output high voltage has self adjustment, which can promote the precision of
adjustment.
FP series power-supply module is specially designed for applications in the circumstance of light load. The efficiency is
up to 75% when output is 1.2W and 85% when output is 5W. In order to achieve light load and high efficiency, the input range
of circuit not like other series of three times high-low ratio reduces to two times high-low ratio.
As FP series power-supply module adopts high-frequency working frequency and provides good condition for filtering. In
the circumstance of adding no filtering, its output voltage ripple is less than 100mV. The temperature stability of frequency
within the entire range of temperature is ±1%.
FP series power-supply module contains an in-built LC network, which can effectively reduce the fluctuations of the
input current and the output voltage.
Key components used for FP series power-supply module are purchased in military level and completely pass the
in-factory test in strict accordance with enterprise standard and the national military product quality standard. All finished
products have experienced 8-hour full-load operation under the temperature of +50 ℃(civil level), + 85 ℃(industrial level)
and +125 ℃ (military level) before delivery so as to fully check the damage to the components during the production process
and hence ensure the reliability of products.
