Output Specifications

Note: (1) Noise is measured with resistor load (not as electronic load). The output is decoupled with 10uF bulk electrolytic

and 0.1uF ceramic capacitor. Measurement is made with a high impedance probe connected across the decoupling

capacitance. Band width limited to 100mHz. (2) The sum of total powered ports cannot exceed 200W.
