SCD30A Current Shunt 30A DC AC Range 10 mV per Amp Output

The Siglent SCD30A current shunt is a precision accessory designed to extend the current measurement range of compatible Siglent digital multimeters up to 30 A for both DC and AC (≤ 5 kHz). It outputs 10 mV per ampere, allowing the meter to interpret high currents accurately via built-in scaling. It supports continuous sampling current readings with high linearity and delivers measurement accuracy better than ± 0.3% at low frequencies. Compatible with SDM3055 and SDM3065X series multimeters (not compatible with SDM3045X). Packaged small, suitable for bench or field use in power electronics, battery testing, or high-current diagnostics.
