The core functions and advantages focus on four dimensions: astronomical adaptation, dual-channel control, flexible programming, and stable reliability:
·Precise astronomical timing adaptation: After entering the latitude and longitude of the device installation location, it automatically calculates daily sunrise and sunset times, and intelligently adjusts switch times with sunlight changes in four seasons without frequent manual modifications.
·Dual-channel independent control: 2 groups of changeover contacts can control two different loads simultaneously (such as street lights + landscape lights), with independent programming without mutual interference, improving control efficiency.
· Multi-mode programming compatibility: Supports 44 groups of custom on/off programs, which can be superimposed with astronomical timing mode (such as turning off lights 30 minutes after sunrise and turning on lights 15 minutes before sunset) to meet complex scenario needs.
· High-reliability design: Equipped with a long-life lithium battery, retaining programs and time memory for ≥3 years after power outage; industrial-grade anti-interference capability, with an operating temperature range of -10℃~+50℃, adapting to outdoor power distribution environments.
·Convenient operation experience: The LCD display clearly shows latitude and longitude, sunrise and sunset times, and program status; key operation is simple, supporting 12/24-hour format switching and automatic daylight saving time adjustment.
The THC 15B-2C is a dual-channel astronomical timer switch specially designed for sunrise-sunset adaptive control, compatible with AC 220V-240V voltage and 50/60Hz frequency, with mainstream rated current specifications of 16A/20A/25A/30A (resistive load). Its core function automatically calculates sunrise and sunset times based on latitude and longitude, supporting four-season time adaptive adjustment. It also integrates 44 groups of programmable on/off programs, automatic daylight saving time switching, and power failure memory (built-in lithium battery life ≥3 years). Adopting 35mm standard DIN rail installation, it has a compact size of 86×36×66mm and an accuracy of ≤1 second/day, widely used in municipal street lights, landscape lighting, agricultural greenhouses and other scenarios requiring automatic control following natural light.
