The core functions and advantages focus on three dimensions: astronomical adaptation, dual-channel control, high reliability:
· Precise astronomical timing: Automatically matches sunrise and sunset times after entering latitude and longitude, intelligently adjusts with seasonal sunlight changes, no manual modification required;
· Dual-channel synchronous/independent control: 2 groups of contacts support synchronous (control the same load) or independent (control two loads) operation, adapting to multi-device scenarios;
Highly flexible programming: 80 custom programs can be superimposed with astronomical mode (e.g., "turn on lights 10 minutes before sunset"), minimum switching time 1 minute;
· Stable and durable: Built-in lithium battery ensures power failure memory; industrial-grade chip resists electromagnetic interference; operating temperature -10~40℃, adapting to complex environments.
The THC 15A-2C is a latitude-longitude driven dual-channel astronomical timer switch, compatible with AC 220-240V/50-60Hz voltage, with rated currents covering 16A/20A/25A/30A (resistive load). Its core function is to automatically calculate daily sunrise and sunset times by inputting the latitude and longitude of the installation location, realizing automatic circuit on/off with natural light. It also supports 80 groups of custom on/off programs, power failure memory (built-in lithium battery life ≥3 years), industrial-grade anti-interference, and DIN rail mounting. Its size fits distribution cabinets, widely used in municipal street lights, landscape lighting, agricultural aquaculture, etc.
