PTC Heaters

PTC Heaters for Constant Battery Discharge

KLC Corporation introduces a high power, compact heater design that utilizes proven ceramic PTC technology to act as the constant power resistor for battery discharge tests. The PTC thermistors used in this high power heater are self-regulating elements that can operate at a nearly constant power over a wide range of voltage and environmental conditions.
