EDISA CORP LRS-75-12 Switching Power Supply, 12V 6.25A 75W, Input 100-240VAC

12V 6.25A 75W enclosed switching power supply with universal AC input for industrial controls and power distribution.

• ‌The LRS-75-12 is a single-output enclosed SMPS (Switch Mode Power Supply).Key internal stages: EMI filter → reduces electrical noise entering/leaving the unit Bridge rectifier → converts AC → high-voltage DC High-frequency switching transistor (PWM controller) Transformer (isolation + voltage step-down) Secondary rectifier + LC filter → smooth 12V DC Feedback loop (optocoupler) → keeps voltage stable
