Nettet31. des. 2024 · Another diode-based protection method is to wire a diode in parallel to your main circuit, causing it to block current when voltage is applied correctly. Instead, the voltage travels through the main load. Once reversed, this diode provides an alternate path for electrons, largely bypassing the main circuit and protecting it from these effects. NettetLPS- RK_SP, LPN-RK_SP, FRS-R and FRN-R fuses are sized for motor running “back-up” protection and provide superb short circuit protection at the same time. LPJ_SP, …
