Air heater LCH series

finnedconvectionelectric

Product overview
PTC Heat Conductors of the LCH series are self-regulating PTC heating elements available in multiple sizes and mounting options. Designed for medium-to-low temperature applications, they combine PTC self-regulation with finned convection or fan-assisted air heating variants to accommodate electronic and appliance heating needs.

Features

• Self-regulating PTC behaviour for automatic power adjustment
• Wide power range from small to high output (6–2000 W depending on model)
• Operational voltage options across 12 V to 600 V (model dependent)
• Aluminum fin construction for natural convection types (AL6061 / AL6063)
• Quiet operation for finned types; optional fan for selected models
• Standard lead wire: 22 AWG, 210 mm (black); custom wiring available
• Customizable dimensions, fins, terminals and mounting holes

Multi-Stage Heating
Optional multi-stage heating (2- or 3-stage) is available for LCH types to provide selectable temperature levels in a single unit, improving flexibility in temperature control.

Applications
Typical uses include PC motherboard heating and protection, steam irons, moisture control, frost protection, medical and beauty devices, air purifiers, electronic heating modules and other medium-to-low temperature systems.

General specifications (summary)

• Power range: 6 W – 2000 W (model dependent)
• Surface temperature range: typically 60°C – 240°C (some types ~220°C)
• Voltage: AC/DC 12 V – 520 V standard; selected models up to 600 V
• Exterior material: Aluminum (AL6061 / AL6063) for finned types
• Standard lead wire: 22 AWG, 210 mm

Application notes

• PTC power and surface temperature depend on ambient temperature, airflow and heat-sink/contact conditions.
• Under low dissipation (no airflow) surface temperature may approach Curie temperature and power reduces; under high dissipation power increases to regulate temperature.
• Maximum listed power refers to conditions near maximum surface temperature; delivered power in real applications typically ranges from ~5% to ~80% of maximum depending on dissipation method.
• Actual performance varies with contact material, heat sink, area, ambient conditions and installation.
• Customization for lead exits, fixture holes, connectors, fin shape and electrical ratings is available.
