PURPOSE:To use a sole power source for a plurality of utilities by switching over the control mode of a power source circuit to produce stabilized DC outputs of different current/voltage characteristics. CONSTITUTION:A power source circuit has an input rectifier 1 including a bridge type rectifier and a smoothing condenser, a starting current controller 2, a blocking oscillator 3, a converter transformer 4, a switching controller 5, an output rectifier 6, an detector 7, a remote control signal input unit 8, and an auxiliary power source circuit 9. The detector 7 and the controller 5 are operated to control the stabilization, thereby supplying the prescribed stabilized DC output to a load 12. Stabilized DC outputs having different current/voltage characteristics is supplied to the load 12 in response to the level of the remote control signal from remote control terminals T3, T4. |
