The ZMPT101B module is a compact single-phase AC voltage sensor module based on the minuscule 2mA/2mA precision voltage transformer ZMPT101B.
ZMPT101B module can handle AC voltages up to 250V (50Hz/60Hz). Its secondary circuitry, centered on the LM358 dual op-amp chip, also allows tweaking the isolated analog output via an onboard multiturn trimpot. The recommended operating voltage of the module is 5VDC.
