![]() PSAL-24 Dimensions |
|
The PSAL-24 has a very small input resistance of approximately 40 mΩ (±10A/±5A/±2A types), enabling highly accurate measurements.
It can also be used for current measurement of low-voltage devices and evaluation of charge/discharge characteristics of batteries and cell batteries.
