Our touch‑safe PTC aluminum heater is designed to stabilize the internal temperature of electrical cabinets and prevent condensation. Adopting PTC self‑limiting heating technology, it avoids overheating risks while delivering consistent heat output. The heater housing uses UL94V‑0 flame‑retardant plastic. Its low surface temperature prevents accidental burns, making it safe for cabinet installation. It supports an AC/DC 12‑24V wide voltage input, with optional power ratings from 50W to150W.
Installed on a standard 35 mm DIN rail, the unit features compact dimensions and simple wiring. It comes with double insulation and IP20 protection grade, suitable for long‑term operation in industrial environments. Widely used in distribution cabinets, wind power systems, railway transit, petrochemical facilities and urban power supply projects. We have obtained CE, VDE, CQC, RoHS and ISO9001 certifications, reliable quality and factory‑direct supply with customization available.
