Manufacturer: Wenchi Electric Ignition Instruments Co., Ltd. Summary: Twist each end of two lead wires together and form a fixed protection zone, make both of twisted ends of two lead wires as the two poles of electric bridge. Because the powder head is small, it is suitable to be put on the mini-type firing things, so the application range is wide. The ignition time is long and the noise is small. It is mainly applied to stage (indoor) fireworks and novelties fireworks. This type of igniter has the top-ranking qualification in the world. All parameters are in the permitted range of related criterion and we absolutely guarantee the ignition of connection in series to be perfectly normal, no phenomenon of failed ignition. Every batch of igniters, quality is stable and we ensure all igniters can be fired in milliseconds. View the drawing three. Main Performance parameters: Resistance: 1.6~2.0Ω Rated ignition current of connection in parallel or single: 0.50A 20ms Rated ignition current of connection in series: 0.80A 5.0ms Firing point current: 0.37A The firing time while the current is 1A: 2ms Safety current: 0.20A 5s Test current: 50mA Lead wire: Φ0.4mm copper-core wire or zincked iron-core wire, covered by PVC.
