Digital meter for measuring and displaying leakage current. Also displays voltage, harmonics, etc. Built-in alarm relay. ★★★ Instruments for distribution boards, control panels, sub-distribution boards, and panels.
This device measures and displays the current flowing through the secondary grounding line of a transformer, and when the value exceeds the set limit, it can prevent accidents in advance through an alarm sound and relay. Features: - Displayed as waveform and vector - Measurement of lg, lgr, and lgc currents - Ability to identify leakage phases - RS-485 communication For inquiries, please contact "lightstar_1979@yahoo.co.jp".

Company information
Our company was founded in 1979 and has grown into a manufacturer of products that can observe electrical data through early analog instruments, digital meters, wireless, and the internet. This development is driven by the strong will of our employees to walk alongside our customers. Additionally, we are committed to thorough customer-centric operations while actively investing in technological development at our affiliated research institute. We strive to meet our customers' diverse needs through more differentiated services. In our case, we have become well-known in South Korea for our measuring instruments (analog, digital meters, and CT, VT). We have been exporting to Japanese companies for over a decade, and we have registered with Ipros to introduce our products to more Japanese customers. In 2022, we registered as a corporation in Tokyo and have since relocated our corporate office to Osaka as "LIGHTSTAR JAPAN." We also have Japanese staff on-site, and we look forward to your support.
