Data acquisition instrument is how to prevent interference of external power supply-CodePudding

We work in the field of instrument is now, but the voltage of the power supply system (and possibly current) is not stable, often occurs in instrument interfering signal, excuse me what method can solve the problem of external disturbance?
We are through the switch power supply to convert 220 v ac to dc 12 v power supply for power supply

CodePudding user response:

The field where the 220 v?
Since 220 v that and what is the difference between ordinary power supply?

The alternating current (ac) is not the utility, is generating their own power generators

This is not a ac mains, is generating their own power generators

The same ah, now to adapt to a wide range of switch power supply, basic it is 100-240 can work normally, you will not exceed the scope of their engine fluctuations?

Now the key problem is the external power ups and downs, cause interference instrument

Used voltage stabilizing device, in order to ensure the power supply is stable, we use the voltage stabilizer and the dual voltage regulator, UPS but there is no change

try to switch to battery power supply

Use for a long time, wasn't the battery

refer to the eighth floor zgl7903 response:

add a try on-line UPS, after detailed describe the interference phenomenon of

Our instrument similar to the oscilloscope, from sensors to receive some waveforms, and external disturbance will let all channels at the same time a very strong signal,

On the car battery to try?
