The concrete technical scheme that the utility model proposes is as follows:

1, a kind of digital power conditioning module, comprise socket (2), the Power Regulation special chip PLX200 parts such as (17) of module housing (1), the output of scalable power, module housing (1) is gone up embedded one and is used to indicate the digital calibration dial plate (10) of power adjustments and the contact button (7) (8) of adjustable output power.

2, adjustable power way of output has two kinds simultaneously, the one, draw by the power output socket (2) in three holes, the 2nd, draw by the binding post of (3) (4) and (5) (6), wherein the power output socket in three holes (2) is arranged on the step of an epirelief of module housing.

3, to go up the graduation mark on the embedded power numeral graduation apparatus dish (10) be that meter full scale is from 0～1400 watt uniformly to module housing (1), and the centre bit of dial plate is equipped with a pointer (9), and what drive pointer is a micro-step motor (18).

4, the lower left corner of power adjustments scale dial plate (10) has touching of an increase power to regulate button (7), the lower right corner has touching of a minimizing power to regulate button (8), has a self-locking total power switch (11), the upper left corner that a luminous indicating diode (15) is arranged in the upper right corner of dial plate (10).

5, on the module housing (1) four binding posts being arranged, is respectively input N (14), the input grounding protection end E (13) of input L (12), the 220V of civil power 220V, an output ground protection end (16).

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

The utility model comprises the adjusting button (8) of module housing (1), three hole accessory power outlets (2), output wiring terminal (3) (4), output wiring terminal (5) (6), the adjusting button (7) that increases power, minimizing power; the input N (14) of input L (12), the civil power 220V of pointer (9), scale dial plate (10), total power switch (11),

civil power

220V, 220V input grounding protection end E (13); light-emitting diode (15), output ground protection end (16), Power Regulation special chip PLX200 (17).
