Devices Feature DIN-Rail-Mountable Packages for Easy Installation in Industrial and Green Energy Applications

Ametherm today announced a new series of inrush current limiting NTC thermistors designed to withstand high input energy of 1200 J and steady-state currents from 50.0 A to 80.0 A at 680 V. Offered in DIN-rail-mountable packages, MM35-DIN series devices are optimized for power distribution in high-power industrial and green energy applications including variable-frequency motor drives, transformers, wind turbines, large inverters, and single- and three-phase motors. The MM35 series is among the products being featured this week in the Ametherm booth (#640) at APEC 2018, taking place through March 8 in San Antonio, Texas.

The MM35-DIN series consists of four thermistors featuring resistance at 25 °C from 0.2 Ω to 1.5 Ω, maximum power of 38.4 W, and thermal time constants of less than 300 s. The devices feature diameters of 68.0 mm with thickness of 8.5 mm and 9.5 mm.

The space- and cost-saving thermistors provide simple one-component alternatives to using power resistors with relays or MOSFETs, greatly simplifying designs. For easy installation, the devices are designed for use with a DIN block. This allows for mounting within a power control box using only a screwdriver.
