Import Ammeter Ess960i — Buy in wholesale FOB from Supplier in China

The ESS960I from Dongfang Yoyik Engnieering Co., Ltd. is a digital ammeter purpose-built for power generation environments, reflecting the supplier's specialisation in thermal and hydroelectric plant spare parts. Unlike general-purpose panel meters, this instrument is designed to integrate with the distributed control systems and switchgear found in Chinese-designed power stations. The model designation follows the pattern of Dongfang Electric Group affiliated suppliers, where ESS prefixes typically denote excitation or electrical system instruments.

Digital ammeters for power plant service typically feature true RMS measurement, 4-20mA or 0-10V analogue retransmission, and serial communication protocols such as Modbus RTU over RS-485. The ESS960I likely employs a current transformer input, with standard ranges of 5A or 1A secondary, though buyers must confirm the exact primary and secondary current ratios, burden, and accuracy class with Dongfang Yoyik Engnieering Co., Ltd. Power plant instruments of this generation commonly offer 0.5 or 0.2 accuracy class for metering and 1.0 for protection, with enhanced electromagnetic compatibility to withstand switchyard interference.

The primary buyers are power plant maintenance departments, original equipment manufacturers, and EPC contractors servicing Chinese-exported generation sets. The instrument's compatibility with Dongfang turbine-generator control architectures is its distinguishing feature. Trade terms, certification status, and exact technical documentation, including wiring diagrams and communication protocol manuals, require direct confirmation with the supplier, as the source description does not detail these elements.

Dongfang Yoyik Engnieering Co., Ltd. is headquartered in Deyang, Sichuan Province, at 4-3F, Building A, Huashan Platz, with postal code 618000. The company identifies as a professional production, development, and sales enterprise focused on power plant dedicated spare parts and accessories. It claims more than 21 years of operational history, though buyers should independently verify this assertion, as the source provides no registration date or third-party confirmation of this tenure.

The supplier holds a harbor trust tier with zero percent response rate and zero recorded response hours, indicating no active platform engagement. Its product portfolio extends far beyond the ESS960I to encompass LVDT sensors, speed sensors, pressure transmitters, excitation regulators, and dry transformers, positioning it as a comprehensive power plant spare parts supplier rather than a pure instrument manufacturer. Buyers should note that no stated export license, ISO certification, or specific client references are provided in the source material, and these would need direct verification with Dongfang Yoyik Engnieering Co., Ltd.
