PIONEER MAGNETICS 80026-508-08-R Closed Switching Power Supply

80026-508-08-R is an original US-manufactured enclosed switching power supply developed by Pioneer Magnetics, 

specially designed as dedicated power source for legacy Allen‑Bradley DC servo drive units. The suffix “R” stands for conformal coated PCB 

version with full anti-corrosion coating against moisture, dust and corrosive ambient gas. This unit supplies stabilized main DC power as well as 

auxiliary control power for drive logic and encoder circuits. The model has been phased out from original production and serves as critical replacement spare 

for aging CNC, metallurgical and paper-making production equipment worldwide.
