Electric convector heater LCH series

ACDCthree-phase

Product overview
The LCH series PTC Heat Conductors are self‑regulating PTC heating elements available in multiple sizes and mounting options. Designed for medium‑ to low‑temperature applications, models include aluminum‑finned natural convection types and air‑heater types that can be fitted with optional fans for forced dissipation.

Key features

• Self‑regulating PTC characteristic for automatic power adjustment
• Wide power range: 6–2000 W (model dependent)
• Voltage options: AC/DC 12 V – 600 V (model dependent)
• Aluminum fin construction for convection models (AL6061 / AL6063)
• Low acoustic emission on finned types; fan optional for selected air‑heater models
• Standard lead wire: 22 AWG, 210 mm (black); custom wiring available
• Customizable dimensions, fin profile, lead exit, terminals and mounting holes

Multi‑stage heating
Multi‑stage (2 or 3 level) heating options are available across LCH types to provide multiple temperature settings within a single unit for greater control flexibility.

Applications
Typical uses include PC motherboard heating/protection, steam irons, humidity control, frost protection, medical and beauty devices, air purifiers, electronic heating modules and other medium‑ to low‑temperature heating products.

General specifications

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

Application notes

• Output power and surface temperature depend on ambient temperature, airflow and contact/heat‑sink conditions.
• Under low dissipation (no airflow) surface temperature may approach Curie temperature and power falls; with high dissipation power rises to regulate temperature.
• Maximum power figures refer to conditions near maximum surface temperature; typical delivered power in applications ranges approximately 5%–80% of maximum depending on dissipation method.
• Actual performance varies with contact material, heat sink, dissipation area, ambient conditions and installation.
• Custom models (dimensions, fin design, mounting hole locations, lead exit, terminals) can be produced to customer requirements (tooling charges may apply).

Dimensions and wire options
Standard LCH types include LCH‑A through LCH‑M. LCH‑H to LCH‑M families feature aluminum fins for natural convection. Wire/output options: single‑side or two‑side lead exit, leads with connector or female crimp, stainless steel mounting plate, three‑phase outlets (new option). If not specified, standard single‑side lead exit without terminals is provided.
