Product Details
C3-200A+ Upper/Lower-Limit Temperature Controller, widely used in solar and heat pump water heating and various other heating applications.
One temperature input uses a BESFUL NTC-220 thermistor with measurement and display accuracy up to 0.1℃, allowing users to monitor temperature trends intuitively;One output controls one relay (NO and NC contacts) for temperature control over a range of 0°C–120°C;Extremely easy to configure: simply adjust the upper and lower limits, and changes take effect immediately.
The wide-range power supply automatically adapts to AC80V–240V for stable, reliable, long-term operation.
Product key features
One temperature measurement channel controlling one relay with normally open and normally closed contacts
Display temperature up to 0.1 degrees Celsius
Setting parameters Power-off memory function
Imported NTC 240K temperature sensor for stable, reliable measurement
Long-distance temperature measurement (100 m) requires no compensation
Switching power supply for stable operation at AC80-240V
