LED temperature control module MT series

programmableindustrialcompact

Overview
The MT series micro temperature and time controller is a patented, compact module designed to add heating control to space-constrained products without PCB redesign. It supports customizable ON/OFF temperature limits and timer settings, with more than 10,000 standard configurations available. Compatible with ultra-thin flexible heaters and low-inrush PTC elements for industrial applications.

Features

• Compact form factor: 20 x 10 x 3 mm — fits confined assemblies
• Simple integration: no extra controller or major circuit changes required
• Flexible power: DC 3.7–24V (USB or battery compatible)
• Fast sampling and control: sampling time <100 ms; temperature accuracy ±2℃
• Multiple control modes: constant temperature, limit (ON/OFF), timer, cyclic timer
• Highly configurable: ON/OFF temperature limits, timer 1–1440 minutes, cycle 1–99 cycles; >10,000 standard variants
• Safety guidance: for external adapters recommend 100–220 µF capacitor to reduce voltage surges

MT Model — Constant temperature examples
Sample model codes show fixed hold temperatures (excerpt):
MT-30XXXX = -30℃
MT-10XXXX = -10℃
MT000XXXX = 0℃
MT010XXXX = 10℃
MT025XXXX = 25℃
MT050XXXX = 50℃
MT080XXXX = 80℃
MT120XXXX = 120℃
MT180XXXX = 180℃ (special)

Notes on models

• Highlighted/standard models have shorter lead times; special high-temperature models available to 180℃.
• Typical max current varies by type (e.g., ~2.5A Type A; 4A Type D). Other specs available on request.
• Custom granular settings: 1℃ steps and 1-minute timer increments up to 24 hours or continuous cycles.

Applications

• Industrial products requiring integrated temperature + time control in minimal space
• Examples: medical heating modules, wearable heaters, optical/camera de-icing, environmental control with low-inrush PTC heaters, integration with ultra-thin heating films
