Jymc220bi Schematic 2021 |top| ✨

Before diving into the schematic layout and wiring architecture, it is critical to cross-verify the electrical limitations of the 2021 revision of the JYMC-220B-I. Operating the board outside of these parameters will result in immediate failure of the silicon control rectifiers (SCRs). 230 VAC ( ), 50/60 Hz

0 to 90V DC (for 110V models) / 0 to 180V DC (for 220V models) 8A to 12A (Continuous rating varies with heat sinking) Compatible Motors Permanent Magnet DC (PMDC) Brush Motors Control Topology SCR (Silicon Controlled Rectifier) Phase Control Potentiometer Rating 4.7kΩ or 10kΩ (Linear taper) 2.
