HKS-VA028-V2.0 is a dual-display digital panel meter designed for real-time monitoring of DC voltage and current. It is commonly used in battery charging systems, DIY power supplies, and automotive electrical troubleshooting. AliExpress Key Technical Specifications HKS-VA028-V2.0
Connects to the true negative terminal of the main load power source.
Provides a low-cost visual upgrade for DIY or legacy analog variable power setups.
: Providing a digital readout for custom-built DIY electronics power stations. or specific pinout instructions for this version? hks-va028-v2.0
is a precision designed for real-time electrical monitoring . It is widely integrated into high-performance automotive platforms, electronic diagnostic workbenches, and custom DIY power supply projects.
If you want a focused deep dive (pinpointing exact specs, pinouts, firmware changelog, installation manual, or step-by-step flashing instructions) provide one of: the product category (automotive ECU, valve actuator, sensor, etc.), a photo of the unit, or a link to the vendor page and I’ll produce targeted technical details and step-by-step procedures.
Typically red for voltage (top) and blue for current (bottom). Voltage Measurement Range: 0 to 99.9V DC. HKS-VA028-V2
The V2.0’s exhaust outlet requires a V-band clamp. You must plumb the dump tube back into the downpipe or vent to atmosphere (check local noise/emissions laws).
The logic supply voltage (thin red wire) is dropping below 4.5V. Switch to an isolated power supply rather than tapping the monitored circuit.
If is a boost control solenoid valve, its likely characteristics include: Provides a low-cost visual upgrade for DIY or
For high-voltage systems (30V to 100V), use an independent battery or step-down converter to power the module.
