Plate heating element LCH series

finnedfanPTC

Product overview
Taiwan KLC’s PTC Heat Conductors (LCH series, LCH-A ~ LCH-M) are self-regulating solid-state heating elements available in multiple form factors, lengths and mounting/wire-output options. Configurations include finned extrusions and PTC thermal plates; some types support optional fan assistance for increased heat transfer.

Features

• Self-regulating PTC characteristic for temperature control
• Wide power range (6 W to ~2000 W depending on model)
• Low electrical consumption relative to required heating application
• Low acoustic emission compared with fan-only heaters (fan optional)
• Available for a wide voltage range (typ. AC/DC 12 V–520/600 V depending on type)
• Aluminum finned housings (AL6061 / AL6063) and plate options
• Multiple wiring and mounting customizations available

New / Multi-stage heating
Multi-stage heating options provide two- or three-stage temperature settings within a single unit and can be applied across many LCH types (LCH-A to LCH-I). The LCH-M is a new PTC thermal plate family offering multiple standard surface-temperature options.

Applications
Designed for electronics temperature maintenance and medium-to-low heating tasks: PC motherboard thermal protection, medical and beauty devices, steam irons, moisture control, frost protection, air purifiers, health/therapy devices and similar applications.

Application notes

• PTC output (W) varies with heat-dissipation conditions: under low dissipation (no airflow) surface temperature may approach Curie temperature and power will fall; under high dissipation power increases to maintain regulation.
• Stated maximum power is under effective heat transmission (surface ~240 °C for many types). Typical delivered power depends on contact material, heat sink, dissipation area, ambient temperature and airflow (often 5%–80% of maximum; indirect water heating typically ~15%–60% of maximum).
• Customized models and tooling are available to meet special mechanical or electrical requirements (tooling cost may apply).
• Relative power example at lower surface temperature: Relative Power(@120 °C) ≈ Max Power × (120 °C – ambient) / (240 °C – ambient) — actual results depend on application conditions.
