This is a non-isolated converter. Input: DC 9-24V. Prohibiting direct short circuit output. hope you could understand. 1X DC-DC 12V 24V to DC 200V-450V 220V 380V High Voltage Boost Converter Step Up Desrcription: this is a DC convert with a huge output voltage of DC 450V. this module is amazing, when the input voltage is not stable, the output will be stable. this is a non-isolated converter.    Parameter:   Input: DC 9-24V lowest starting voltage: 8.4V Output:adjustable DC 220V-450V (MAX 450V the output voltage is stable even the input voltage is changing) Power: 40W continuously working, it can reach 70W occational working.Input voltage is lowered, the output power will drop, the input voltage increases, the output power increases, but does not affect the output voltage Size: 85*50*28MM Undervoltage protection: yes. when the input is less than 7.6V, the voltage will not be boosting Reverse connection protection: yes Indicator: the led will be on when the charging is finished Charging time: to charge 1000UF capacitance to 450V, it will take about 5 seconds   Notice:  when the power is big, the assurance may burn, you need to change to get the module back to work.   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 booster plate using low end limiting mode, that is, the low pressure side of the current restrictions, especially for charging the capacitor, we should all know the capacitor charging voltage is zero before time, direct charge, (in this case equivalent to short-circuit state) Any flow is not enough, easy to burn booster. This version can directly access the following 1000UF capacitor charging, 1000UF or more, preferably a series 5W, 10 European cement resistance about limiting it.   2. Not suitable for other big power electrical power supply, due to the current limit, output overload of work when the output voltage down. Will cause the output voltage instability phenomenon.   3. The use of lithium and other power supply, pay attention to the protection board can withstand enough current time, the current shortage will lead to damage to the protective plate, or protection board protection leads to insufficient input voltage undervoltage protection, resulting in no boost.    4. Found that many of my friends like to use with 9V battery powered multimeter used, such cells are laminated battery, the output current is limited, the battery capacity is small, if the capacitor is charged to 1000UF, 450V, the first charging rate very slow, and the second is very uneconomical, probably 1-2 times after charging the battery, there is no electricity.   5. When using a power shortage when to recharge the battery when it will cause the input supply voltage is low, the charge rate will be much slower. For example the use of 12V, 2A of power supply voltage will be pulled down to approximately 8.4V.     6. The capacitor in parallel with the output of more than just time and charging capacity will not appear light, generally parallel capacitance in capacitor voltage is not enough, resulting in the leakage voltage will never reach the set voltage value, so it does not light, so much Only when each individual test capacitance measured after good capacitance in parallel.   7. The board for the high-voltage output, high risk !! safety! Prohibiting direct short circuit output.   8. There are many of my friends always ask is how much of this output current, the output voltage is adjustable structure in different output voltage when the output current is different, the formula is 70 (power) divided by the output voltage is equal to output current to charge the capacitor when the concrete to due process of charging voltage has been changing, so at a different voltage point, the current output is different, it is a dynamic current.   9. There are a lot of customers to charge the capacitor after discharge, do not want to disconnect input power boost module tested way discharge switch module output to be used in series with a 10-20 European cement resistance between capacitance method, For SCR discharges, you can not use this method.     Package Included: 1x 70W High Voltage DC-DC Boost Converter  Refund
