Than the use of materials, than the quality of the pressure adjustment module is the best material on Taobao, the design is the most perfect.
What is the reason?
1 no external +12V DC power supply.Some products need to provide you with +12V power supply, and there are power precision requirements for you to use caused great inconvenience and annoyance. This product does not require the user to provide DC power supply.
2 no external synchronous transformer (or other trigger module) is required for this product.Due to the reasonable design, the use of space for you to use, but also to simplify the installation and wiring. At the same time, less wiring also reduces the possibility of poor contact.
3 control methods for the full COMpatibility.You can use potentiometer control, you can also use a variety of automatic signal control (such asFour-20mA, 0-5VDC, 0-10VDC, etc.), a module can be COMpetent for a variety of applications, control handy. This allows you to select a simple, easy to prepare, to avoid the loss caused by the wrong type selection.
4 control accuracy is very high.Users usually ignore the observed accuracy of this parameter. Extremely narrow range of products, some adjustment, such as 4-20mA control, the actual range only 6-13mA (stunning); some even unable to output 0 or unable to output the maximum. Such immature products are worth pondering.
FiveUsing imported ST high power silicon controlled silicon as the core component of the module.High quality products are not only the pursuit of the user, but also our reputation and life.
6 this series has a close loop negative feedback function, to meet the needs of different levels of customer.Some customers need to have a negative feedback function of the voltage regulator module for very high requirements of industrial applications, for no suitable products and worry. Division I for this part of the high requirements of the customer specially developed thisSelf voltage negative feedback three-phase voltage regulator module, no external power supply, trigger module, the use of very convenient.Welcome users before and after sale to do technical exchanges with us!

9There is a power indication.green light(input signal indicator.Red lightStatus indication ()Yellow light) three color indication.
10,Products suitable for three-phase four wire circuit, AC 380V + 10%, frequency: 50Hz. Automatic identification of phase sequence, into line circuit R, S, T phase requirements. If the user needs to be used in other voltage, or zero line, can be customized to my company.
The product has three color lights, the problem can be judged by the lights:
green lightPower indicator light. If L and N (220V power) no electricity, the green light is not bright, this time should check whether the L and N are in good contact. Please pay special attention to N and L can not be connected to the anti.
Red lightInput signal indicator. If the input signal is the smallest (or has not yet access control signal), the red light is not bright. The red light intensity represents the intensity of the input signal. The greater the control signal, the more bright red light, the voltage output value of the module is also greater.
Yellow lightStatus indicator light. When the module output is zero, the yellow light is bright, and the yellow light is not bright when the output voltage is output.
Yellow lightLight conditions have the following:
1. Missed any control mode, the module output voltage is zero.
Two There is a control signal, but the control signal is very small, at this time the module output voltage is zero.
ThreeOver temperature alarm. If the temperature of the module itself has reached 75C, the module will automatically stop working. At this point should be promptly cut off the power supply, to strengthen the cooling and then continue to work.
Product load output current levels and models are as follows:
long105 xwide75 xhigh36mm
Full compatible input control mode
Unique fully compatible input control mode to enable the product to0-5Vdc,0-10Vdc,4-20mA,1-5Vdc,0-10mAAnd other automatic methods are able to adapt, do not need special custom, can also be used to manually control the potentiometer.
4-20mAcontrol mode:According to the icon, can accept the temperature control table, such as the 4-20mA analog signal, the module's internal 4-20mA terminal relative to the input impedance of COM is 250. When this method is used, the +5V end and the CONT end are suspended.
Manual control mode of potentiometer:According to the icon, the middle end of the potentiometer is connected to the module CONT end, and the other ends of the potentiometer are respectively connected to the module COM end and the +5V end. When the control side CONT from the 0-5Vdc change, the AC load voltage from 0 V to the maximum linear adjustable, CONT voltage is higher, the greater the module output. 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 2-10K Omega between. In this way, the '4-20mA' end is suspended.
0-5Vdccontrol mode:According to the icon, can accept the MCU and other 0-5Vdc analog signal, the input control of the positive pole connected to the CONT terminal, negative electrode connected to the COM terminal, the module internal CONT end of the input impedance is greater than 30K COM. When this method is used, the +5V and the '4-20mA' end is suspended.
0-10Vdccontrol modeAccording to the icon, can accept 0-10Vdc and other analog signals, the module's internal 0-10Vdc end of the input impedance is greater than 15K COM. When using this method of "4-20mA" end suspended, +5V terminal and COM terminal short circuit, 0-10Vdc control signal from the 0-5Vdc control terminal via entering.
0-10mAcontrol modeAccording to the icon, this method should be used in the module CONT and COM between the end of a 500 ohm, 1/2W resistance, when the input 0mA corresponds to the CONT 0Vdc, when the input 10mA corresponding to the CONT 5Vdc.
Matters needing attention in control terminal:
1, the function of the end of the relativecomEnd must be positive,comThe end of the negative electrode, such as the polarity of the module is connected to the main circuit output terminal may be out of control.
Module 2, each side of the control characteristics are positive characteristic, control, and the higher the voltage, the output voltage of the module of high voltage main loop.
3, at a time appropriate to use an input control, if more than two ways to use the same time, it is generally a strong input signal a major role. To use both manual and automatic, such as automatic4-20mAHand in hand0-5VFunction switch can be performed by a double throw switch.
4If silicon controlled silicon in the module can be long time output large current (i.e. main circuit input voltage is very high, the output voltage is low), which may lead to serious heating of the module.
