This product is a high‑power‑density communication power supply for industrial applications, entirely developed, tested, and manufactured in‑house by our company. It complies with national standards, features a compact 1U form factor, and delivers exceptionally high power density, with peak efficiency reaching up to 96%. The module incorporates multiple built-in protection functions, ensuring safe and reliable operation. Communication protocols include Modbus and are compatible with Tonghe’s proprietary protocol, supporting RS‑485 interfaces, making it highly versatile and suitable for a wide range of application scenarios. When paired with monitoring systems, it can be integrated into complete communication power supply systems, DC switchgear panels, or all‑in‑one power solutions.
The ZLCL module developed by Shijiazhuang Tonghe Electronics Technology Co., Ltd. is responsible for acquiring essential DC voltage/current, battery‑pack temperature, digital input data, and controlling digital output dry contacts in the DC system, and it uploads this data to the monitoring host via RS485/CAN interfaces.
The SDYKZQ module developed by Shijiazhuang Tonghe Electronics Technology Co., Ltd. is primarily used in applications where dual‑channel AC incoming lines require control of the line contactors. The product features acquisition of two AC voltage channels, seven digital input channels, and RS‑485 communication capability.
