GB/T 36049-2018Household and similar adjustable frequency converters—Model naming method (English PDF)

3.1 Adjustable frequency converter

Converter which can perform the frequency regulation function. [GB/T 29486-2013, Definition 3.9]

3.7 Independently mounted adjustable frequency control

Adjustable frequency control intended for permanent connection to fixed wiring, but intended to be mounted away from the controlled equipment. It may be either.

-- for surface mounting such as on to a wall;

-- for flush mounting, such as into a wall cavity, when installation shall be possible from the front;

-- for panel mounting, such as onto or into a control panel, when installation may be from the rear.

NOTE: Rewrite GB/T 14536.1-2008, Definition 2.5.5.

4.1 Model composition

The model of adjustable frequency controls consists of category code, control object code, input rated voltage code, input frequency code, input current code, mounting type code, application product category, plant design sequential code, etc. of adjustable frequency controls.

4.2 Coding principles

4.2.1 Code X1

Code X1 is the category code of adjustable frequency controls, which is represented by two capital pinyin letters.

4.2.2 Code X2
