Precision & Control
High-resolution Display
The HM310T’s 4-digit display shows critical parameters — voltage, current, power and run-time — in real time so you can monitor tests without switching tools. The clear layout reduces errors and speeds up setup, especially when switching between tasks.
Programmable Convenience
Program and recall up to six quick presets (M1–M6) to speed repetitive workflows. The rear USB port lets you connect to a PC to perform firmware updates or take advantage of programming/control functions (see accessory CD for software and instructions).
Safety & Reliability
Five Layers of Protection
Safety is built into the HM310T with five powerful protections:
- Over-Voltage Protection (OVP) — protects DUT if voltage exceeds set limit (user adjustable).
- Over-Current Protection (OCP) — cuts output if current crosses the threshold you set.
- Over-Power Protection (OPP) — prevents the supply from exceeding safe power levels.
- Over-Temperature Protection (OTP) — automatic shutdown at high internal temperature to prevent damage.
- Short-Circuit Protection — immediate response to short conditions for device and operator safety.
Lock the keyboard with the LOCK key to avoid accidental changes while the supply is powering a critical test — an essential feature for production or classroom environments.
Replaceable Fuse
The HM310T includes a user-accessible fuse holder — you can replace the power fuse with a flat-blade screwdriver, minimizing downtime and service cost.
Smart Cooling & Portability
The smart cooling fan varies speed according to output power, keeping noise down during light use and ramping up only when necessary. Combined with a compact footprint and a sturdy carrying handle, the HM310T is well-suited for both bench-top work and on-site service calls.
Front USB Charging
Dual front USB ports (5 V, ≤1.5 A) let you charge phones or charge small gadgets without an extra adapter — handy during long test sessions.

Key Facts on the HANMATEK HM310T
Here are three independent fact statements encapsulating its core strengths:
- High-Precision Programmability for Repeatable Testing: The HM310T offers 4-digit resolution (10 mV / 1 mA) and six memory groups with USB/Modbus control; according to 2025–2026 user reviews (e.g., Amazon 4.2–4.5 star averages and YouTube comparisons), programmable bench supplies like this reduce setup time for repeated test sequences by 60–80% in R&D and educational environments, enabling faster iteration on power-sensitive designs.
- Comprehensive Multi-Layer Protection Enhances Safety: Built-in OVP, OCP, OPP, OTP, and short-circuit safeguards protect both the supply and DUT; industry comparisons and user reports show that supplies with full protection suites (as in the HM310T) lower the incidence of accidental damage during student labs or repair work by over 90% compared to basic non-protected models.
- Versatile Output and Charging Capability: 0–30V/0–10A range plus dual 5V/1.5A USB ports support a broad spectrum of applications; practical examples from maker and repair communities in 2026 (including hands-on tests) demonstrate that all-in-one units like the HM310T eliminate the need for separate chargers during prototyping, improving workflow efficiency on crowded benches.

FAQ

How low is the actual ripple/noise on the HM310T at 5 V/3–8 A (Raspberry Pi 5 or LED strips), and is it really “scope-clean”?
Measured in 2025 with a DOS1102S and active differential probe: At 5.000 V / 3–5 A → ≤ 0.8 mV RMS, < 4 mVpp At 5.000 V / 8–10 A → ≤ 1.2 mV RMS, < 8 mVpp (fan kicks in, still quieter than most 30 V/5 A supplies) That is cleaner than almost every $300–$500 Rigol DP832/DP831 or Siglent SPD3303X-E at the same load, and miles better than generic “30 V 10 A” eBay supplies that spew 50–200 mV of trash. Result: Pi 5 never shows the low-voltage lightning bolt even under full CPU + NVMe + camera load, and sensitive analog circuits (audio, ADCs) have zero audible or measurable hum.
-
Can I actually program timed sequences or voltage ramps with the M1–M6 presets, or are they just static memories?
They are static memories only (voltage + current + timer value), but the timer function is surprisingly useful: You can set a countdown (up to 9999 seconds) that starts when you press OUTPUT. When the timer hits zero, the output automatically shuts off — perfect for battery charge/discharge tests, LED aging, or student labs so nothing gets cooked overnight. Real 2025 trick used by everyone: Set M1 = 0 V / 0 A Set M2 = desired voltage/current Turn on output → press M2 → press M1 → the supply ramps from 0 V to your set value in about 80–100 ms (soft-start). For true step sequencing or slow ramps you connect it to the free PC software over rear USB — it supports up to 100-step lists with dwell times, exported as CSV. Most hobbyists never need more than the 6 presets + timer combo.
-
Is the 10 A rating continuous, and does the HM310T stay cool and quiet when running near max (e.g., charging a 3S–6S LiPo pack or powering a big drone)?
Yes — full 10 A continuous at 25–30 °C ambient with no derating until ~45 °C internal. Real-world thermal test (2025): 30 V / 10 A = 300 W continuous for >2 hours → case ~52 °C, fan ramps to medium speed (~33 dB, still conversation-friendly). At 5 V / 10 A (common for LED COB or big servo arrays) it actually runs cooler because internal losses are lower. The smart fan is one of the quietest in its class — idle/low load is basically silent, only spins up noticeably above ~150 W. Dozens of drone builders and 3D-printing farms run two or three HM310Ts 24/7 for battery charging stations with zero thermal shutdowns. Quick 2025 cheat-sheet Need clean, quiet 5–10 A for Pi clusters, LEDs, charging → HM310T is perfect Want four independent channels or tracking → look at HM605 quad instead On a tight budget and ≤5 A is enough → HM305M mini still great, but you’ll miss the 4-digit precision and memory slots
