ST-8E 8-Port Cloud-Based Smart Power Manager
Interaction and Display: Equipped with an embedded RTOS system and GUI library, featuring a 4-inch 480×800 HD touchscreen supporting Chinese-English language switching. Compatible with external displays of the same specifications. Triggers pop-up alerts with audible beeps during protection activation or fire alarms.
Smart Control and Protection: Provides 8 channels of high-voltage control with overvoltage, undervoltage, and overcurrent protection. Supports three operating modes: Standard, KTV, and Video. Features infrared control, channel delayed power on/off, 24-hour cyclic scheduling, and fire alarm linkage functionality.
Network Integration & Centralized Management: Equipped with a 100Mbps Ethernet port, compatible with TCP/IP, MQTT, and other protocols for integration with mainstream cloud platforms. Supports RS232/RS485 bus control and unlimited device cascading. Host computers can centrally monitor voltage, current, and other operational data across multiple devices via network or serial port.
Function Features：
1. Embedded RTOS multi-tasking real-time operating system with GUI (Graphical User Interface) library for interactive user interface;
2. 4-inch high-definition touchscreen display with 480×800 pixel resolution;
3. Overvoltage protection, undervoltage protection, and overcurrent protection settings. When protection triggers, the display shows a pop-up alert indicating the cause, accompanied by a buzzer warning. Can also be configured for direct protection without display alerts;
4. Power-on/off delay settings: Each channel supports individually configurable delay times from 1 to 999 seconds (default 1 second);
5. 3 operating modes: Standard, KTV, Video. Modes can be set individually via the touchscreen;
6. Features a 10/100M Ethernet port supporting full compatibility with TCP/IP, UDP, RTU, MQTT, and HTTP protocols. Connects to Huawei Cloud, Alibaba Cloud, Baidu Cloud, Tencent Cloud, and OneNET, and integrates with multiple standard MQTT protocol platforms;
7. Unlimited device cascading via RS232 connection (supports up to 10 meters);
8. Centralized control via RS232/RS485 with configurable baud rates (4800-921600, default 9600). Supports parity bit (enable/disable function) and reads all device data;
9. Chinese/English language switching;
10. Electricity consumption tracking: cumulative total, single-session accumulation, and multiple-session accumulation (in kWh);
11. Cumulative operating time (minutes), with 2 sets of local 24-hour cyclic timer functions;
12. 8-channel high-voltage control, supports fire alarm switch; fire alarm trigger displays pop-up alert on screen with continuous buzzer alarm, resets upon power cycle;
13. Infrared control with switchable control modes;
14. External 4-inch HD display supports mode switching, protection settings, and dual-language (Chinese/English) display;
15. Host computer enables centralized control of multiple devices via TCP/IP, displaying voltage, current, power, and switch status. Also supports serial port control with dual-language (Chinese/English) switching.
