Since it is an unregulated power supply the output will depend on AC input voltage. The circuitry includes a passive EMI filter consisting of elements C8, C9, C4, T1, and L1.  Bridge rectifier D1, R1 for inrush current protection, and a relay RL1 for soft powering up and reducing conduction losses in steady-state. 4 x electrolytic capacitors C2, C3, C6, C7 are used for buffering the rectified DC bus voltage, bleeding resistors R1, and R2 provided to discharge the DC bus capacitor after power off. It is advisable to use a heatsink for the bridge rectifier. Inrush current circuit requires\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e12-15V DC @ 80mA\u003c\/strong\u003e.
