Siemens plc switching power supply selection method

In the field of industrial automation control, power supply is required for stable operation of equipment in the control system. Siemens SITOP power supply has strict standards in terms of stability and reliability, effectively preventing the equipment and production lines from being stopped due to power supply problems, thus ensuring the efficiency of plant operation and maximizing customer benefits.
In the control system composed of Siemens plc, sometimes according to actual needs, a suitable switching power supply should be selected to supply power to the equipment. In this article, I will introduce you to the selection method of switching power supply for users to refer to during use.
The selection of switching power supply selection mainly considers the following aspects:
1. Parallel or series operation When one power supply cannot meet the required voltage or current range, two or more power supplies (or different outputs of the same power supply) can be used in parallel or in series. In this mode of operation, the link between the regulation and control circuits between the various power modules still exists, except that one power supply acts as the master and the other power source is used as the controlled party.
2. Pulsation and noise The ideal DC power supply should provide pure DC. However, there are always some interferences, such as the ripple current and high frequency oscillation superimposed on the output port of the switching power supply. These two kinds of interference, together with the spike noise generated by the power supply itself, cause intermittent and random drift of the power supply.
3, overload protection Because a power supply to supply different circuits, the current flow of these circuits may be unknown, in order to avoid damage to the power supply, you need to set the scope of the protection circuit.
Almost all power supplies have the following characteristics: When the output range is exceeded, either the output remains at the maximum output value or the power is turned off by itself. In addition to the programmable output range, some programmable power supplies can also automatically set the type of power stable output. That is to say, when the voltage or current required by the external circuit exceeds the set limit, the power source can automatically change from a constant voltage source to a constant current source or a value stream source to a constant voltage source.

4. The internal resistance of the internal impedance is relatively large. There are two disadvantages to the load. Firstly, it is not conducive to the operation of the load voltage regulator circuit. What is more unfavorable is that any change in the load current will cause the output of the DC power supply to fluctuate. The effect of the fluctuation on the test results is exactly the same as the impact of the pulse and noise on the test results.
5. Stability When the line voltage or load current changes elbow, the output voltage of the DC power supply will also fluctuate. The degree of regulation is determined by the parameters of the voltage regulator circuit. The parameters refer to the capacity of the filter capacitor and the rate of energy release.
If a relatively constant power supply is supplied to the power supply, then only basic load regulation is required. The magnitude of stability is generally defined as the percentage of output voltage at no load or full load, or the change in voltage.
In summary, Siemens SITOP power supply provides users with a more stable and reliable power supply guarantee. By selecting and using the Siemens SITOP power module, the user can provide powerful support for the power supply of the automation control system, thus ensuring the stable operation of the control system. During the configuration of the automation control system power supply, the user can refer to the method provided in this article for configuration.

3D Printing Motor

3D printing on the pen machine is mainly used in 3 d printing pen, is made from a special custom Dc Gear Motor, mainly used in 3 d printing pen, pen 3 d printing machine has been updated three generations according to the requirements of product.


3D Printing Motor product introduction:

The 3D Printing Motor is based on the deceleration Motor, coupled with supporting gears and ball bearings.The role of the gear reducer is to provide lower speed and greater torque.At the same time, gear box different deceleration ratio can provide different speed and torque.It's mostly rolling.

Operating temperature range:

3D Printing Motor should be used at a temperature of -10~60℃.

The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.

If a 3D Printing Motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.


Storage temperature range:

3D Printing Motor should be stored ta a temperature of -15~65℃.

In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.


Service life:

The longevity of 3D Printing Motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.

●Use with a load that exceeds the rated torque

●Frequent starting

●Momentary reversals of turning direction

●Impact loads

●Long-term continuous operation

●Forced turning using the output shaft

●Use in which the permitted overhang load or the permitted thrust load is exceeded

●A pulse drive ,e.g.,a short break,counter electromotive force,PWM control

●Use of a voltage that is nonstandard as regards the rated voltage

●Use outside the prescribed temperature or relative-humidity range,or in a special environment.

●Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
