After adopting such scheme, soon being fixedly mounted on each components and parts in the switch cubicle originally concentrates in the less casing of volume, only need mobile box during use, it is whole mobile just can to drive adjustable DC power supply, therefore, direct current operative power source of the present utility model carries very convenient, have direct current and two kinds of selection modes that exchange input because of it again, under the state of the place that can't obtain AC power or outage, the mode that can adopt the direct current input is to the electricity consumption electric, so the DC power supply scope of application of this kind device is wide, practical; And because whole device is integrated in the less casing, wiring is relatively just more stable, is not easy to cause the circuit open circuit in the handling process, has improved the job stability of device.

The dividing plate of more preferably above-mentioned casing of the present utility model is provided with the pressure regulation handwheel, is connected also to play the pressure regulation effect on the pressure regulation isolation module.

Also be provided with a voltmeter and an ammeter on the dividing plate of more preferably above-mentioned casing of the present utility model, voltmeter is connected in parallel on the rectifying and voltage-stabilizing module, ammeter is connected between DC out-put supply port and the rectifying and voltage-stabilizing module, be respectively applied for the size that shows output voltage and output current, more directly perceived.

An input mains switch and an out-put supply switch also are set on the dividing plate of more preferably above-mentioned casing of the present utility model, the keying of control input power supply and the keying of out-put supply respectively, and respectively carry an input power safety and out-put supply insurance.

The both sides of more preferably above-mentioned casing of the present utility model are provided with a pair of button that draws, and are convenient manually mobile.

The front of more preferably above-mentioned casing of the present utility model also is provided with two snap closes, is used for fastened housing and housing plate.
