Thermoelectric Peltier Cooler Heatsink Cooling Plate Cooler Module Heatsink 26mm Outer Diameter 10mm Inner Diameter TES1-04903 5V3A

Feature: 1. Does not need any refrigerant, can work continuously, there is no pollution source, no rotating parts, no rotation effect, no sliding part. A solid piece without vibration, noise, possess long life and easy installation 2. Semiconductor refrigeration fins have two functions, both cooling and heating. The cooling efficiency is generally 55-60%, but the heating efficiency is very high and always greater than 1. Therefore, one piece can replace separate refrigeration system and heating system 3. The semiconductor refrigeration chip is a current-transducer type chip. Through the control of the input current, high-accuracy temperature control can be realized. Coupled with temperature detection and control means, it is easy to realize remote control, program control, and computer control to form an automatic control system 4. The thermal inertia of the semiconductor cooling fin is very small, and the cooling and heating time is very fast. When the hot end has good heat dissipation and the cold end is empty, the cooling fin can reach the maximum temperature difference in less than one minute Specification: Item Type: Thermoelectric Cooler Module Model: TES1-04903 Material: Ceramic Rated Voltage: DC5V Maximum Voltage: DC5.78V (Th=30) Maximum Current: 3A (U=5.78V, Th=30) Maximum Temperature Difference: 66 (Qc=0,Th=30) Maximum Cooling Capacity: 9.5W (T=0,Th=30) Internal : 1.27-1.43Ω Specification: 22AWG, L: Approx. 150mm / 5.9in Package List: 1 x Thermoelectric Cooler Module

• [NO REFRIGERANT NEEDED] This solid-state thermoelectric cooler operates without any moving parts, refrigerants, or pollution sources. Its vibration-free, silent design ensures long lifespan and easy installation for continuous operation in sensitive environments.
• [DUAL COOLING & HEATING] With 55-60% cooling efficiency and >100% heating efficiency, this module replaces separate systems. Ideal for precision temperature control in electronics, medical devices, or scientific equipment where both functions are required.
• [PRECISE TEMPERATURE CONTROL] The current-transducer chip enables accurate temperature regulation through input current adjustment. Compatible with remote/computer control systems for automated temperature management in industrial or laboratory settings.
• [RAPID THERMAL RESPONSE] Achieves maximum temperature difference in under 60 seconds when properly configured. The low thermal inertia makes it perfect for applications requiring fast thermal cycling or quick stabilization of sensitive components.
• [REVERSIBLE POWER GENERATION] Can be used for thermoelectric power generation in low-mid temperature environments. Suitable for energy harvesting applications or as emergency power source in remote monitoring systems.
