Package size: 150 * 130 * 60mm / 5.91 * 5.12 * 2.36in
Item weight: 136g / 4.80ounces
Package weight: 200g / 7.05ounces
About the output impedance matching problem of the current generator:
1. The internal resistance of the output signal must meet the following requirements:
According to the formula: I=U/R (current = voltage divided by resistance). So your voltage divided by your signal internal resistance is equal to the maximum current that your signal receiver can generate. In addition, our current generator has a certain internal resistance.
2. Here's the formula:
Supply voltage/(signal impedance of the customer+internal resistance of our current generator)=constant current output.
Since the supply of our module is 4-35V voltage, the constant flow current generated by the module will not be sufficient if the supply voltage is low and the internal resistance of the customer is larger.
3. Here is a signal matching requirement for our module:
* supply is 24V, the signal impedance ≤ 1000Ω
* supply is 12V, the signal impedance ≤ 500Ω
* supply is 5V, the signal impedance ≤ 200Ω
If the internal resistance of your signal is higher than the above parameters, you can improve the supply voltage or reduce the signal internal resistance to lve the problem of insufficient current supply of the constant current source.
Please kindly note that the supply voltage cannot be increased to more than 28V.
Note:
The product supports 3.7V rechargeable lithium battery, but not support dry battery.
