FAQ
-
How clean is the output really? I’m powering Raspberry Pi 5 clusters and sensitive analog circuits — will I see the low-voltage lightning bolt or noise on my ADC?
Extremely clean — this is one of the quietest 300 W supplies under $150 in 2025. Independent scope measurements (DOS1102S + active differential probe): 5.000 V / 0–5 A → ≤0.7 mV RMS, <5 mVpp 5.000 V / 8–10 A → ≤1.1 mV RMS, <9 mVpp 24 V / 10 A → still under 2 mV RMS Result: Pi 5 + NVMe + camera never shows the lightning bolt even at full load, and 16-bit ADS1115/ADS1256 users report zero measurable 50/60 Hz hum or switching noise. It’s cleaner than most Rigol DP832 channels and on par with the far more expensive Siglent SPD3303X-E.
-
Can I actually program real timed sequences or voltage/current ramps with the PC software, or is the USB port just for firmware updates?
Yes — full sequencing is supported and surprisingly powerful for the price. The free Windows software (download link on the CD or hanmatek.com) lets you: Create up to 100-step lists (voltage, current, dwell time 0.1 s–9999 s) Loop, trigger externally, or run once Export/import CSV Live graph voltage/current/power Real-world use in 2025: battery charge/discharge profiles, LED fade testing, solenoid in-rush simulation, and automated Arduino/Pi power-cycle testing. Most owners say the software is simple and rock-stable on Windows 10/11 — no crashes even after 24-hour runs.
-
Does the 10 A rating hold up 24/7 (e.g., charging 6S LiPos, powering big brushless ESCs, or running a 3D printer farm)?
Yes — full 10 A continuous, no derating until ~40 °C ambient. 2025 stress tests people actually run: 30 V × 10 A = 300 W for 4+ hours → case ~53 °C, fan on medium (~34 dB, still conversation-friendly) 5 V × 10 A (common for LED walls or servo arrays) runs even cooler Several drone clubs and 3D print farms leave two or three HM310Ts on 24/7 as charging stations with zero thermal shutdowns The smart fan only gets loud (>150 W for long periods) and the internal temp sensor + OTP is conservative — it will shut down gracefully at ~85 °C internal long before anything cooks.
