Power supply accessories -DC 3.7V-7.4V to 1000kV power supply module Highlights generic brand DC 3.7V-7.4V to 1000kV power supply module Description: This high voltage generator module is based on the coil principle. You're here. This small, high-efficiency module can release high-voltage pulse output with a simple external circuit power supply. Ideal for students to study electrical experiment, do science experiments, etc. Input: 3.7V - 7.4V / 4A Output Voltage: 800KV - 1000KV / 0.5A Specification: Dimension: 88.5 x 26mm (LxD) Input Voltage: DC 3.7V - 7.4V Input Current: 4A Length input wire length: 10cm (Red positive Green negative) Output voltage: 800KV - 1000KV (please be careful when using) Output current: 0.5A Output wire length: 16cm Discharge time : 10s Arc distance / High voltage discharge distance range: 15mm - 20mm Power supply: 1x 3.7V lithium battery, 2x 3.7V lithium batteries in series (like 18650 battery), NiCd / NiMH batteries, lead acid batteries -4V/6V acid, etc. (6V battery is recommended for the best effect) Package includes: 2 Pieces 3.7V to 1000KV Power Supply Module Generator Note: 1. The high voltage module should not be under voltage when it is in high state. no-load voltage. (The power supply should be adjusted to a suitable distance from the high voltage output line, the battery capacity and voltage are proportional to the distance of the high voltage arc) 2. During the experiment, please please test the arc distance from short to long, DO NOT exceed the maximum arc distance, or the high voltage energy may not be released and it may easily damage the module. 3. Input voltage affects output voltage and arc distance. 4. The module power is large, and the heat dissipation inside is small. Please let the module work intermittently, continuous work should not be longer than 1 minute. Incorrect voltage and long working hours can easily damage the module.
