【鉄道模型】鉄道模型用パワーパック・ショート時の事故リスク軽減の為にコンデンサの交換と動作の比較 #鉄道模型 #パワーパック #工作

If you're interested in model trains or railways, please subscribe to our channel! Regarding the power pack we built last time, it was pointed out that the electrolytic capacitor used in the PWM speed controller had a large capacitance, posing a risk of a large current flowing from the capacitor even when the current was shut down in the event of a derailment short circuit. It was suggested to replace the electrolytic capacitor with a smaller capacitance ceramic capacitor. This time, we will replace the capacitor. We also compare the operation of the product in its default state, without the capacitor, and after replacing it with a ceramic capacitor. If you build this using the same parts, please take the above issues into consideration and proceed at your own risk. Below are the parts used in the construction, and the total cost for one unit was approximately 986 yen.

Other necessary components include a case, various lead wires, and an AC adapter. A 12V 1A AC adapter is required. These are typically found in laptop or external HDD shops for around 300 yen. 0:00 Opening 0:06 Background to this project 1:21 Insulation treatment of the voltmeter 1:58 Operation check in default product state 3:33 Removal of electrolytic capacitor and operation check without capacitor 5:42 Installation of ceramic capacitor and operation check 8:40 Slow-motion playback of what happens when an electrolytic capacitor shorts 9:17 Summary #Model trains #Power pack #Project ----------------------------------------------------------------------------------------------------------------- I create videos on various topics, including model trains and games.
