The W1 Power meter is designed to be used as a stand-alone unit that may be powered from a self-contained battery or an external power source. Optionally, it may be built into existing equipment or an enclosure of your choice. See Assembly Options on page 3 for more information.

The W1 uses no surface-mount technology, so it’s an ideal project for first-time builders.

Note: This product is a kit which may involve building the product by selecting individual components, soldering them to the circuit board, winding toroids, installing LEDs and displays, calibrating circuits to meet specified performance levels.
