Color word is very important, please be sure to read the new and old customers

Open loop, the output voltage is determined by the control signal, but at the same time with the change of the external factors, such as the fluctuation of the voltage of the grid, the load type and the load power increase or decrease. If the output voltage is determined only by the given control signal and not changed with the external factors, the negative feedback circuit is used to realize the.Open ring products in most industrial occasions enough to meet the needs, such as the need for accurate temperature control, the temperature control instrument+Open loop voltage regulator module combination to achieve.

Closed loop (negative feedback) advantages are: output voltage regulator, when the input side of the power grid voltage fluctuations, or the output side of the load changes, the module output value is always kept constant. Recommended for the stability of the output voltage requirements are very high customer use.

If need to increaseClosed loop voltage stabilizing function (negative feedback), may contact us to choose the product with the negative feedback function. Increase the closed-loop type than the open loop50Yuan, closed type is completely the same with the connection mode of the open loop. The closed loop model is added on the basis of the open loop model.-F(FbyFeedbackMeaning of feedback.

For the first time using this product, please refer to the following table for selection, or contact us to help type selection! Correct selection is very important!

Three, adjustable dieBlock should beUse range:

Heating: all kinds of heating furnace, injection molding equipment, thermoplastic molding, textile equipment, infrared heating, power distribution system, drying system, etc.

Motor: fan motor, water pump motor, mixer motor, etc.

Lighting: public lighting, industrial lighting, stage lighting, etc.

Other: transformer, inductance coil, electric welding machine, electroplating, etc.

Input terminals each functional mode use instructions

• 
  Unique fully compatible with input control mode, 0-5Vdc, 0-10Vdc, 4-20mA, 1-5Vdc, 0-10mA and other automatic methods are able to adapt, without special custom, can also be used to manually control the potentiometer. The input range is wide, the output regulation precision is high, and the anti-interference ability is strong.
  

The potentiometer manual control mode: according to the icon, the middle end of the potentiometer is connected to the module 0-5V end, and the other ends of the potentiometer are respectively connected to the module COM end and the +5V end. 5V voltage by the module itself produced, without the need for external supply, with only hand control potentiometer with and without it, the selected resistance value of the potentiometer in an 4.7-10K. When the control side changes from the 0-5Vdc, the voltage from 0 V to the maximum value of the AC load can be adjusted, the higher the voltage of the 0-5V terminal, the greater the output voltage of the module.

0-5Vdc control mode: according to the icon, can accept the MCU and other 0-5Vdc analog signal, the control input positive pole connected to the 0-5V terminal, negative electrode connected to the com terminal, the module internal 0-5V terminal relative to the input impedance of COM is greater than 30K. When the control signal end of the change from 0-5Vdc, on AC load voltage from 0 V to the maximum value of linear can tune, the signal in 0-0.9Vdc about for the whole closed area, reliable off the output of the whole circuit; signal in about 0.9Vdc-4.8Vdc for adjustable region, that with the increase of voltage control, phase angle alpha from 180 degrees to 0 DEG linear decrease, the conduction angle is increased, the AC load voltage from 0 V increases to the maximum value; signal in 4.8Vdc-5Vdc about for the whole open area, the voltage on AC load for maximum value (i.e. voltage).

0-10Vdc control mode: according to the icon, can accept the 0-10Vdc analog signal, 0-10Vdc module internal com end of the input impedance is greater than 15K.

4, a 4-20mA control mode: click on the icon, acceptable temperature control gauge 4-20mA analog signal, the module internal 4-20mA end relative com end of the input impedance for 250 ohms. When the 4-20mA control input. 4-4.8mA about for the whole closed area, reliable off the output of the whole circuit; 4.8-19.5mA around to the regional, that with the increase of current control, phase angle alpha from 180 degrees to 0 DEG linear decrease, on AC load voltage from 0 V increases to the value; 19.5-20mA around for the whole open area, maximum output.

Fifth, 0-10mA control mode: as shown, when used in this way must be between the module 0-5V end and the com end connected to a 500 ohm, 1 / 2W resistance. When the input 0ma 0-5V end to 0vdc. When the input 10mA 0-5V end from 5VDC.

2Each function end is opposite to the com end must be positive, the com end is the negative pole, such as the polarity connection counter then the module main circuit output end may be out of control.

3, the control characteristics of the end of each function module are positive characteristic, control, and the higher the voltage, higher output voltage of the module of high voltage main loop.

4At some point, it is better to use an input control mode, if two or more ways to use the same time, it is generally a strong input signal a major role. The module can be used both manually and automatically, such as automatically connected to the 4-20mA end, and is connected to the 0-5V terminal manually, and the function switch can be performed by a double throw switch.
