FAQs – High Voltage PTC Heaters 1 What voltage ranges do KLC High Voltage PTC Heaters support? KLC's High Voltage PTC Heaters cover 12V to 999V, with UL/CSA certification standard for systems up to 600V. The MH, MSH, SH, TH, OH handle 12V–500V applications, while the STW series extends to 999V with fully custom sizing — covering everything from auxiliary 12V systems to 800V+ EV and industrial platforms. What are the available models for 400~500V applications? Five model families cover the 400–500V range: MH(W), MSH(W), SH(W), TH(W), and OH(W) — each with different fin widths (30mm to 90mm) and...

How to choose the right model? Depends on voltage, dimensions, power, operating temperature, and application. KLC's engineers can provide guidance for optimal selection. See step by step guide to select your PTC heater and Contact us for your thermal solutions. Is a high voltage PTC heater (above 500V) safe to integrate into my system? Yes. KLC's STW series provides UL-standard high voltage insulation, on top of the inherent self-regulation of the PTC ceramic element itself — the element physically cannot draw enough current to overheat, regardless of voltage class. Thermostats and safety fuses...
