Small size, high ... moreefficiency, simple external circuit( just plug in the switch, the battery can be) discharge intensity violent. Specification: Voltage: Input DC3.6-6V. Output DC400kV- 600KV( Please note that when security) High Type: Pulse Current High voltage bipolar discharge distance: 10mm-20mm Output voltage lines Length: about 100mm Input power cable length: about 10mm( red is positive) Dimensions: Φ24* 63mm About Power: 3.7V Li-ion battery can be used single or two series. Such as 18650, idle cell phone batteries( to remove the protection board, the proposed capacity of 2000mAh or more) or NiCd/ NiMH battery pack, 4V or 6V Lead Acid batteries. This module is a small production with high-pressure science inverter transformer/ booster finished module. The input terminal DC3V-7.2V voltage can get 200,000 volts DC high voltage( about 1-2 cm arc) at the output can be used as high school science experiments, electronic equipment, negative ion generator, high voltage source to use when making small science. Note: Avoid high-pressure high-voltage module load electricity use. Must adjust the high voltage side suitable distance( before electricity. Battery voltage and capacity is proportional to the distance from high-voltage arcing used when testing the arc distance from short to long experiment, prohibited from beyond the arc when powered up, the energy can not be released due to high pressure, easily damage the module. Due to power. The internal heat is not easy, every power-on time should be controlled within a minute. Determine whether the battery capacity can be driven approach is the maximum power output of the battery when the voltage measurement arcing. If so you can 6V maximum power output.

While regulating the“current potentiometer” so that the output current reaches a predetermined overcurrent protection value. For example, the meter displays the current value of 4A, then you can use the module to a maximum current of 4A) 3) Connected to the load. 2、Use as a battery charger Usage: 1) Make sure you need to charge the battery float voltage and charging current; if lithium parameters 3.7V/2200mAh. Then the float voltage is 4.2V, the maximum charging current 1C, ie 2200mA) 2) Under no-load conditions. Adjust the“Voltage potentiometer” so that the output voltage reaches the float voltage; if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V) 3) use a multimeter to measure the output short-circuit current with 10A stalls. While regulating the“current potentiometer” so that the output current reaches a predetermined Charging current value. 4) Charge turn lamp current factory default is 0.1 times the charging current; Battery during charging current is gradually reduced.
