Power monitoring for Arduino projects, Raspberry Pi power supplies, and portable power stations. Understanding the Wiring (Installation Guide) HKS-VA028-V2.0 generally uses a two-harness system to function properly. Thin Wires (Small Harness): Red: Power Supply for the Meter (Connect to + Black: Ground (Connect to - Thick Wires (Large Harness): Red: Current Input (Connect in series to the load)
The 0–100V threshold accommodates 12V, 24V, 36V, and 48V battery systems commonly found in off-grid solar kits, electric bicycles, and mobility scooters. It helps monitor precise discharge rates and guards against damaging over-depletion. Troubleshooting Tips Understanding the HKS-VA028-V2
. These modules are popular because they integrate two essential measurements into a single, space-saving unit. The V2.0 revision often includes minor improvements in power efficiency or measurement stability over previous versions. Core Specifications
DC 4–30V (Note: Exceeding 30V on the power input will damage the unit). Accuracy: Typically ±1%. Dimensions: Approximately 48mm x 29mm x 26mm. Wiring Guide The device usually comes with two wire harnesses: Thin Wire Harness (Power & Sensing): Red: Power supply positive (4–30V). Black: Power supply negative/ground.
