TDK NSRG JA73G027AD Power Supply

The TDK NSRG JA73G027AD is a 25 VDC, 10 A industrial power supply used to feed PLCs, motor drives and control panels in harsh environments. Common failure points on this model include burned-out rectifier diodes, overheated MOSFETs or IGBT modules, damaged output capacitors, and failing protection ICs that trigger over‑current or short‑circuit shutdowns. Begin troubleshooting by verifying input voltage stability, checking for visible signs of component burn or corrosion on the board, and measuring the output under no-load to confirm 25 VDC delivery; if abnormal, inspect the rectifier bridge and MOSFET gate drive circuitry before proceeding to component replacement.[oss-gpt-20b] Post Comment
