Hks-va028-v2.0 -

The is a dual-display digital panel meter designed for real-time monitoring of DC voltage and current. It is widely used in DIY electronics, solar power systems, and automotive diagnostics due to its compact size and integrated shunt (for the 10A model). 🛠️ Key Technical Specifications Voltage Range: 0 to 100V DC.

: Reviewers on Amazon have mentioned that the meters are "accurate, durable, and easy to install". However, one user warned against bending the wires too sharply, as PCB flex can cause errors in current measurement.

Connect the thin yellow wire to the positive rail of the target high-voltage system.

Place your handheld multimeter in series to verify exact current draw. Adjust the potentiometer slowly to correct any offset on the current display. Common Troubleshooting Scenarios

The hardware architecture of the hks-va028-v2.0 focuses on minimal power consumption and versatile measurement capabilities. Below is a comprehensive breakdown of its electronic attributes: Specification hks-va028-v2.0 (Often cross-referenced with DSN-V288) Measurement Range (Voltage) DC 0V to 100V Measurement Range (Current) DC 0A to 10A (Internal shunt included) Module Operating Voltage DC 4V to 30V (Independent power input) Self-Operating Current ≤is less than or equal to Display Window Three 0.28-inch LED digital tubes Display Palette Dual-color (Red for Voltage, Blue for Amperage) Resolution 0.1V (Voltage) / 0.01A (Current) Measurement Accuracy ±plus or minus ±plus or minus Sampling Refresh Rate Approximately 300ms to 500ms per cycle Physical Dimensions Panel Cutout Size Operating Temperature -10°C to 65°C Wiring Topologies and Harness Functions

Based on HKS’s product naming conventions, this identifier most likely corresponds to a or a related electronic boost control accessory, specifically the HKS EVC (Electronic Valve Controller) series.

: Operating voltage positive terminal ( + DC 4.5V–30V). Powers the internal microcontroller and dual LED displays.

Current input (connects to the negative side of the load). : Reviewers on Amazon have mentioned that the

Connects to the negative terminal of the power source.

Tracks real-time current draw and voltage sag on lithium-polymer (LiPo) bench testers.

Key implication: expect interaction with vehicle systems, engine sensors, actuators, or firmware flashing tools—so electrical, mechanical, and software compatibility matters.
