Product Description
100% Brand New and High Quality
Desrcription:
This is a DC convert with a huge output voltage of DC 250V. this module is amazing, when the input voltage is
not stable, the output will be stable. this is a non-isolated converter.
Parameter:
1. Input:
DC 9-24V
2. Lowest starting voltage: 8.4V
3. Output: adjustable
DC 100V-250V
(MAX 250V the output voltage is stable even the input voltage is changing)
4. Power:
40W continuously working, it can reach 70W occational working.
lnput voltage is lowered, the output
power will drop, the input voltage increases, the output power increases, but does not affect the output voltage.
5. Size: 85*50*28MM
6. Undervoltage protection:
yes
. when the input is less than 7.6V, the voltage will not be boosting
7. Reverse connection protection:
yes
8. Indicator: the led will be on when the charging is finished
9. Charging time: to charge 1000UF capacitance to 450V, it will take about 5 seconds
10.
Notice: when the power is big, the assurance may burn, you need to change to get the module back to work.
11. Recommand power supply for the converter: DC 12V lead-acid battery or 3/4-series of 18650 batteries, which can provide a current over 7A.
Purpose:
magnetizing charging capacitor DC power supply equipment, test fixture, the product pressure test tubes low-voltage DC power supply, glow tube power, and other purposes.
Note:
1. The use of low-voltage side of the current limiting mode, is to limit the low-side current, especially for the capacitor to charge, the capacitor before charging the voltage of 0, the direct charge, (this time is equivalent to short-circuit state) This version can be directly connected to the following capacitor 1000UF charge, more than 1000UF, to a series of 5W, 10ohm cement resistance around what about.
2. Not suitable for other power supply too much power, due to current limiting, the output in the overload when the output voltage will be pulled down. Will cause the phenomenon of unstable output voltage.
3. When using lithium battery and other power supply, pay attention to the protection board can withstand enough current, the current will lead to damage to the protection board, or protection board protection lead to insufficient input voltage protection, resulting in no boost.
4. Many customers like to use 9V multimeter with the battery power supply, this type of battery is a laminated battery, the output current is very limited, the battery capacity is very small, if the 1000UF, 450V capacitor charge, the first charge speed is very slow, The second is very uneconomical, probably charging 1-2 times after the battery is no electricity.
5. When the power supply is low, charging the battery will cause the input supply voltage to be pulled low and the charging speed will be greatly reduced, for example, using 12V, 2A power supply, the power supply voltage will be reduced to about 8.4V.
6. Output more than the capacitor in parallel when there will be and charge capacity will not light, the capacitor is generally parallel to the capacitor voltage is not enough, leakage voltage will never reach the set voltage. So light is not light, So many capacitors in parallel when it is recommended that each capacitor alone test, the capacitor test and then parallel.
7. This board is high voltage output, high pressure danger !! Note safe! Direct short circuit output is prohibited.
8. Many customers always ask how much this output current is, the output voltage is adjustable structure, at different output voltage, the output current is different, the formula is 70W divided by the output voltage is equal to the output current. Specific to the capacitor when charging, because the voltage during the charging process has been changing, so at different voltage points, the output current is different, is a dynamic current.
9. A lot of customers to charge the capacitor after the discharge, do not want to disconnect the boost module input power, through the test switch discharge can be used in the module output to the capacitor in series between a 10-20ohm cement resistance method, for With the discharge of thyristor, this method can not be used.
