OWH9800 Series Digital Power Meter AC/DC 1000V 20A

About Us

The argument in favor of using filler text goes something like this: If you use real content in the Consulting Process, anytime you reach a review point you’ll end up reviewing and negotiating the content itself and not the design.

OWH9800 Series Power Meter

+ Two-channel design
CH1 (rear panel): AC input – Supports 3–600V / 0–20A RMS, with an accuracy of ±0.5%
