Abstract

The utility model discloses a digital/axial angle converter which is a number / mode conversion module. The digital/axial angle converter converts the binary digital quantity which represents the angule into the autosyn or the rotary transformer formal analog quantity to be exported. The digital/axial angle converter comprises an input transformer, an output transformer, a number / mode conversion and power amplification circuit, a digital quantity input compatible TTL and a CMOS electrical level. The standard autosyn or the rotary transformer signal is exported. The digital/axial angle converter is provided with higher conversion precision and stronger load capacity. The thin type digit-axial angle converter adopts the aluminium base process. Compared with the traditional digit-axial angle converter which adopts the printed plate process, the digital/axial angle converter improves the radiation efficiency and decreases the volume and is easy to install. The digital/axial angle converter is simultaneously provided with over pressure, overcurrent and overtemperature protection function, which reinforces the reliability.
