Product Description

The working voltage range is parameter The output current is 5-30mA. The frequency accuracy in each range is 2%. The voltage range is 3V-30V the frequency range is 1Hz-150kHz/1Hz-15kHz.

The square wave generator can be used for experimental development, as a square wave signal generator for motor drivers, as an adjustable pulse generator for microcontrollers, as an adjustable pulse generator for speed regulation, and much more.

An LCD display shows frequency and duty ratio on a clear screen.

A normal mode & an accurate mode with 2 modes are available.

This controller offers three key features lock function PWM output, which allows you to set the frequency and duty cycle independently capable of adjusting the upper and lower duty cycle bounds support for serial communication all data saves automatically after being set.

Questions & Answers

Would it be possible to use this as a 7? The room frequency is being influened by an 83 hz (Schumann resonance) generator. What applications are related to this, or are they totally unrelated?

Let me start by saying that I know nothing about the application for which you intend to use it. In light of that, this device does not have the ability to dial down to. There are only whole numbers on 83 Hz. Hope this helps. From now on, the output is DC square wave.

When you keep frequency on, the duty cycle setting is not applied by default. How can you make sure that the frequency is controlled? Since this is the case, it is very difficult to control the frequency. ?

There is no pulse generator here in the hunt for pulses. Among the features of this PEM generator are its fixed frequency and variable width. What you may be looking for is something along the lines of the following A Player Servo ESC Consistency Digital Tester for Radio Control Servos, Version One Both items can be sold on EBAA under "4S for Speed Controller" and "Electronic Speed Controller Servo Tester ESC for RC Airplane Helicopter"

The program will still work at version What are the input/output voltages of the device? Does your company offer any other similar product that meets this requirement?

I am not sure how you intend to do it Still, it does what it is supposed to. Several control options are available There is more than one purpose to them, meaning that they serve many I no longer use the unit because I found it difficult to use and frustrating. $150 is the cost of the commercial property I bought.

It was specified that serial communication would be used Serial is not discussed in detail, but it does appear to be easy to connect ?

This is the model I bought (XY-) The serial communication protocol for PWM1 is not available It did have that feature in the specification of a model that was available. The model I own is not the one I purchased.

For home brewing, it's the perfect PWM generator

5/5

With this great little PWM generator, it's easy to control manual devices when paired with a PID (which is often the case). As the SSRs are optically coupled, it is safe to drive one with a PID and the other with this PWM device. This is because the two SSRs are wired in parallel. This is good, so why is it The PID is used to bring the wort to a boil, and then the PWM is used to control how much boiling happens. By driving the LCD display with the rotary encoder, the power setting can be easily reproduced.

Good price, good product

5/5

This device worked well after I used it to pilot an MC 2100 motor control board, no problems at all with it.

A diversity of application types and system power requirements

4/5

Please click here. Purchased this so that I could operate a treadmill The process of setting up PWM frequency and duty cycle was a bit long, but all in all it was As a result, I will simply throw a toggle in between the PWM signal and let it start/stop. This enclosure will definitely fit inside of an electrical box with a single bay (my favorite quick enclosure). The treadmill motor and controller will be a great finishing touch when a treadmill is retrofitted to a piece of shop.

Good value for the money

5/5

I find that this device is ideal for my needs, given the price. Config and use of the software are both straightforward. The accuracy and stability of this app are not so important to me, but it seems reasonably accurate and stable from my purposes. I have recommended this product to many others who also have the same requirements as I do, and they have all purchased them and have been pleased by them.

This is excellent

5/5

I am very pleased with the results. I love it. Using this, I was able to manually control the leveling of my headlights. This is definitely an upgrade from the more affordable open-source alternatives These devices have a board style PWM. I highly recommend this product!.

Set up is challenging and the interface is difficult to It produces the outputs that are desired, but it isn't intuitive This is a very good tool, but very hard I found it somewhat confusing to use

3/5

I couldn't figure out how to operate it easily.

I found it very helpful

5/5

The easiest way to do it was to Put the pulse on - It generates power.
Well, this worked out really well. We were able to choose between a wide range of frequencies as well as duty-cycles There must be a cycle and a voltage level. The interface is intuitive and robust.

Drok DC, corrigendum Five-volt battery 30V The current required would be 30mA at 1Hz The duty cycle of the output pulses can be adjusted for 150kHz. The program worked as advertised and did exactly what was expected.
