昭和電子工業 List of Products and Services

The "119C-ES model" is a measuring device that can measure the voltage and current of the AC system, the current, voltage, and power of high-voltage distribution transformers, rectifier circuit current, feeding circuit current, DC bus voltage, etc., in substations that adopt ME-type distribution boards, and display and record data in a specified format. The recorded data can be output to reports using a computer with a dedicated application installed via an SD card, and data transmission can be done using a commercial LAN. [Measurement Specifications (Excerpt)] ■ Response Time: Load Measurement 100ms; Fault Measurement 1ms ■ Measurement Accuracy: Error within ±1% of full scale, etc. *For more details, please download the PDF or contact us.

The "119C-EA model" is an AC measurement device that is used in substations equipped with ME-type distribution boards in the 50Hz range. It measures the current, voltage, and power of each line of high-voltage distribution transformers (distribution transformers), as well as the voltage and current of each high-voltage line, processes the data, and stores it. It can display and record the specified data on the main unit's LCD screen when needed. Additionally, this data can be saved to a memory card and output to a report using a computer. 【Measurement Specifications (excerpt)】 ■ Current measurement range: Rated current AC5A [Measurement range] 0.02A to 7A ■ Voltage measurement range: Rated voltage AC110V [Measurement range] 30V to 150V; (zero phase) 10V to 190V ■ Response time: 100mS (for voltage, current, and power) ■ Measurement accuracy - Voltage/Current: Error within ±1% of full scale - Power: Equivalent to JISC1216 ordinary class, etc. *For more details, please download the PDF or contact us.
