Model Number:MK-JF/220E
Model: MK-JF/220E AC voltage negative feedback module 0-5V control
Various types of voltage regulation and control modules produced by our company, such as fully isolated single-phase/three-phase AC voltage regulation modules, single-phase fully-controlled rectifier modules, and regulators composed of single-phase/three-phase phase-shift trigger modules (series) The voltage system, etc. are all open-loop voltage regulation systems, that is, the output voltage of the system composed of these modules is determined by the control voltage (added to the CON terminal and the COM terminal), but it also changes with other external factors, such as the power grid. The rise and fall of the voltage, the increase or decrease of the load power, and the size of the power factor, etc. If the output voltage is required to be determined only by a given control voltage without changing with external factors, a voltage negative feedback system must be used to achieve it. According to the requirements of the majority of users and the experience of our company, we have developed a class of DC/AC voltage negative feedback modules with good versatility. Time lag and different load performance requirements, such as response speed, stability and other indicators, may not fully meet user requirements, please pay attention when purchasing.

Note 1: The last digit of the model is the input/output control signal type, E F G H can be selected. E means 0-5V; F means 0-10V; G means 4-20mA; H means 1-5V.
Note 2: The output control signal CON of the negative feedback module is 0-5V, so the control signal input type of the matching module must be E type (0-5V).

Wiring diagram
1. The terminal 220V is connected to the 220VAC power supply (the terminal 380V is connected to the 380VAC power supply) (regardless of polarity), and it is provided to the module as a power supply.
2. Terminal URL is a negative feedback voltage, and Uf1 and Uf2 at both ends are connected to both ends of the AC load (Uf1 and Uf2 have no polarity).
3. The functions of CON, COM, Ug and +5V of the weak current part are completely the same as the DC voltage negative feedback module.
4. The principle of the AC voltage negative feedback module is completely the same as that of the DC voltage negative feedback module. Because the strong electric part and the weak electric part are completely electrically isolated inside the module, the module can be automatically controlled safely and conveniently by a computer or the like.
