HM310T — At a Glance

 

Core Power & Accuracy

The HANMATEK HM310T delivers an output range of 0–30V and 0–10A, making it suitable for a wide range of electronics tasks — from powering small modules to supplying current-hungry circuits. With a voltage resolution of 10 mV and a current resolution of 1 mA, the HM310T provides the fine control needed for precise testing and development.

Specifications

Tip: Use M1–M6 quick memory keys to store commonly used voltage/current/time combinations — ideal for repeated tests or production checks.

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.

Real-World Use

Who benefits from the HM310T?

Whether you’re a design engineer validating prototypes, a repair technician servicing electronics, a student learning circuits, or a maker building battery packs, the HANMATEK HM310T blends accuracy, safety and convenience in one device:

• Engineers: run repeatable tests using saved presets and monitor power draw precisely.
• Technicians: protect sensitive modules with adjustable OVP/OCP and short-circuit protection.
• Educators & students: clear display and lockable controls make demonstrations safe and repeatable.
• Makers & hobbyists: compact size and USB charging simplify bench organization.

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

What are the exact output limits of the HANMATEK HM310T?

The HM310T supports 0–30 V and 0–10 A output. Voltage resolution is 10 mV and current resolution is 1 mA.

How many presets can I save?

You can store up to 6 quick parameter groups (M1–M6). These store voltage, current and time values for quick recall.

Can I lock the front panel to prevent accidental changes?

Yes — press the LOCK key to disable the keypad and prevent unintended adjustments while the supply is active.
