NGB250/NGB425/NGB660/NGB800 Power Supplies

Advanced Energy / SL Power NGB250, NGB425, NGB660, and NGB800 Switching Power Supplies are single-output devices that meet medical and industrial safety standards. The NGB250 devices provide an output power of up to 250W with airflow, only derating to 180W convection-cooled. The NGB425 series offers up to 425W with airflow and up to 300W convection-cooled, while the NGB425 units feature up to 660W with airflow and up to 400W convection-cooled. The NGB800 series provides up to 800W with airflow and up to 500W convection-cooled. Advanced Energy / SL Power NGB250, NGB425, NGB660, and NGB800 Switching Power Supplies meet Class B emissions levels and feature a universal 80V_AC or 85V_AC to 264V_AC input range and <100µA leakage current.
