... Effi ciencies of around 55% may be realized for loads up to 1.0W in 120VAC applications, with around 50% effi ciencies for loads up to 800mW in 230VAC applications. A logic-level enable input allows the SR086 to be disabled – useful when it is employed as a keep-alive power supply. WARNING! Galvanic isolation is not provided. Dangerous voltages are present when connected to the AC line ...

... Output Voltage* V may be adjusted in the range 50V*‚ by changing OUT feedback resistor R according to the following equation. 5 Leave R at 12.4kΩ or less - it assures a minimum 100µA 6 load required for the proper operation of the SR086. Change R and R according to the and C with appropriate voltage ratings ...
