Output characteristic
Matters needing attention
The power supply needs to be filtered to prevent damage to this product caused by instantaneous high currents;
If there are obvious surges in the product's operating environment, it is necessary to add protective circuits such as TVS tubes;
Avoid falling, hitting, and puncturing hard objects;
Avoid product exposure to water and strictly prohibit water immersion;
It is strictly prohibited to disassemble the casing to avoid product damage.
Disclaimer
Use of media beyond regulations;
Exceeding the specified power supply voltage for use;
Use beyond the specified temperature range;
Use beyond the specified pressure range;
Severe deformation or damage to the isolation membrane caused by improper operation;
Force majeure, such as product damage caused by lightning strikes, etc;
Other product damage caused by failure to use in accordance with the requirements of this specification.
Note: The accuracy of a product refers to the error rate between the theoretical output value (calculated according to the output formula) and the actual measured value.
That is, accuracy=(measured value - theoretical value)/net output
Net output: 4.5-0.5=4
