Compact structure with stable and reliable performance, specifically designed for use in electric meter test systems.
Utilizes imported photo receiving components, providing excellent noise immunity and strong resistance to external interference.
High optical pulse sampling frequency up to 200 Hz, fully compatible with various meter light sources (blue, yellow, and green LEDs).
The dual-channel sampler supports free adjustment in the up, down, left, and right directions; the minimum adjustable spacing is 1 cm (loosen the nut for fine adjustment).
Red LED indicates active energy (active power) signal; green LED indicates reactive energy (reactive power) signal.
