Leakage Current Alarm Multimeter (Electronic Multimeter) 'KDQ-310'
KDQ-310
Multimeter equipped with leakage alarm function and various electrical element measurement functions ★★★ Instruments for distribution boards, control panels, distribution panels, and panels.
- Leakage Current Alarm Function Used to prevent leakage accidents in circuits, it connects with up to 16 zero-phase current transformers to measure current. When the current value exceeds the set threshold, it generates an alarm signal and sound. - Measurement Function Measures necessary electrical safety management parameters including line-to-line voltage, phase voltage, current, leakage current, active power, reactive power, apparent power, power factor, frequency, active energy, reactive energy, temperature (1CH), and phase. - Circuit Breaker Status Display and Control Function Receives input from circuit breaker status contacts to display the status with LEDs and generates relay contact output for circuit breaker control purposes.

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.
