Ametherm (www.ametherm.com) launched NTC thermistor solutions for Li-ion batteries and green energy applications, including its PANR 103395-342 probe assembly with ring lug for high-accuracy temperature compensation and measurement and its MM35-DIN Series and MS35 Series of inrush current limiters for reliable high-power circuit protection.
“Whether they’re being used for energy storage in solar plants or to power electric vehicles, batteries are a cornerstone of green energy, and their performance relies on accurate and reliable NTC thermistors,” said Mehdi Samii, vice president of engineering at Ametherm.
“Sensors like our PANR 103395-342 help prolong Li-ion battery life and increase safety during the charging cycle, while our MM35-DIN Series and MS35 Series provide protection against inrush current at turn on in high-power renewable energy applications. We can’t wait for these solutions to make their Battery Show debut.”
For Li-ion battery power applications, the ring lug of Ametherm’s PANR 103395-342 probe assembly provides easy and secure mounting to battery terminals.
The device is extremely accurate and experiences minimal drift from its initial electrical values to provide a high-stability replacement for thermocouples in electric vehicle batteries and off-grid energy storage. The temperature probe features a 4000 VAC dielectric withstand voltage, resistance at + 25 °C of 10 kΩ, beta of 3950 °K, and dissipation constant of 8 mW/°C.
Ametherm’s MM35-DIN Series NTC thermistors are designed to withstand high input energy of 1200 J and steady-state currents from 50 A to 80 A at 680 V.
Offered in DIN-rail-mountable packages, these inrush current limiters are ideal for high-power industrial and green energy applications, including variable-frequency motor drives, wind turbines, large inverters, single- and three-phase motors, and transformers. The MM35-DIN Series features resistance at 25 °C from 0.2 Ω to 1.5 Ω, with maximum power of 38.4 W.
The rugged MS35 Series NTC thermistors are optimized for high-power applications, such as wind turbines, solar power inverters, EV battery chargers, and electric vehicles.
Designed to withstand high input energy from 500 J to 900 J and steady-state currents from 10 A to 50 A, these devices offer resistance at 25 °C from 0.5 Ω to 20 Ω and thermal time constants from 65 s to 240 s. Featuring a diameter of 38 mm and thickness less than 10 mm, these thermistors do the same job as a power resistor and relay, but in a smaller, single-part alternative that saves valuable circuit board space.
Ametherm products are available direct from Ametherm or through distributors such as Digi-Key and Mouser.
