The technical problems to be solved in the utility model is, can only be applicable to the defective that specific occasion, versatility are not high at above-mentioned frequency converter, and a kind of unit frequency converter is provided.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of unit frequency converter, the input terminal, outlet copper bar, power panel, lightning protection plate, resistance board, drive plate and the control board that comprise mounting panel and be fixed on described mounting panel front also are provided with the ground connection installing hole that grounding nut is installed on the described mounting panel.
In unit described in the utility model frequency converter, described control board is provided with the interface of external control device.
In unit described in the utility model frequency converter, described input terminal is single spindle bodily form terminal.
In unit described in the utility model frequency converter, top and this input terminal that described input terminal is positioned at described mounting panel are provided with three inlet wire copper bars, and described outlet copper bar is positioned at the bottom of described mounting panel.
In unit described in the utility model frequency converter, the interface on the described control board is a serial ports.
In unit described in the utility model frequency converter, the edge of described mounting panel is provided with a plurality of installing holes.
In unit described in the utility model frequency converter, the both sides of the edge of described mounting panel are provided with a plurality of oval installing holes.
In unit described in the utility model frequency converter, the lower limb of described mounting panel is provided with a plurality of inverted U-shaped installing holes.
In unit described in the utility model frequency converter, the top edge of described mounting panel is provided with a plurality of Pear-Shaped installing holes.
Unit of the present utility model frequency converter owing to there is not shell, can directly be installed in the rack of relevant device, has improved the integrated level of relevant device.In addition, because above-mentioned frequency converter does not have front shroud, front and rear baffle, so the continuity of ground connection is preferable, has saved material simultaneously, reduced cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
