: Up to 10A DC (internal shunt) or higher with an external shunt. Power Supply (Operating Voltage) : DC 4.5V to 30V. : Dual 0.28" LED digital tubes, usually in (Voltage) and (Current). Voltage Error Current Error Physical Dimensions : Approximately mm with a mounting cutout of AliExpress Core Features Dual Monitoring
The user is most likely looking for the HKS "Velocity Advanced Computer" (VAC) or "Speed Limit Defencer" (SLD). These are the products HKS is famous for that the VA028 designation most closely aligns with. hks-va028-v2.0
Current output (connects back to the negative terminal of the power source). : Up to 10A DC (internal shunt) or
. 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 Raspberry Pi power supplies
Compared to earlier versions like the V1.0, the often includes:
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)
Unlike cheaper static alternatives, the rear PCB surface of the V2.0 features . Users can manually fine-tune the calibration of both voltage and current scaling using a precision screwdriver to correct sensor drift over time or account for inline resistance losses. Auto-Shifting Decimal Point
