1Unique fully COMpatible input Control mode,0-5Vdc,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. The input range is wide, the output regulation precision is high, and the anti-interference ability is strong.

Manual control of the potentiometer: according to the icon, the middle end of the potentiometer is connected to the modulecontThe two ends of the potentiometer are respectively connected with the module.COMEnd and+5VEnd. When the control sidecontfrom0-5VdcChanging the voltage on the load from0V to the maximum linear adjustable,contThe higher the terminal voltage, the greater the output of the module.+5VVoltage by the module itself, without the need for external supply, with only hand control potentiometer with and without it, the selected resistance value of the potentiometer in2-10KInter.

2Function end relativecomEnd must be positive,comThe end of the negative electrode, such as the polarity of the module main circuit output end may be out of control.

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

4, when the output end and the General Assembly electrolytic capacitor filter, due to mutations in the voltage on both ends of the capacitor can not be, this high voltage, large capacitive occasion is likely to cause modules over-current damage, so module of electricity shall ensure the control endcontVoltage in0Vor4mAAfter power up,contShall be gradually increased from the low position to ensure that the capacitor impact current is minimized.

5At 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 for both manual and automatic functions, and the function can be switched by a double throw switch.

6If 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. If the actual use of the load voltage is low, the voltage can be reduced by using a three-phase transformer, and then the voltage of the rectifier can be used.LSC-TH1PxxFYandLSC-TH0PxxFYLow pressure series.

5The module should be used in conjunction with the radiator, and there is enough heat radiation space between the cabinet and the other devices. When necessary, can be installed fan forced cooling. The cooling effect is not only concerned with the actual use of the size of the current and the radiator, with ambient temperature (summer and winter), ventilation conditions (natural cooling, forced cooling air volume), and install density and other factors are related. The third, threeR,S,TThe input end of the DC output is negative, the output DC positive.
