Kyoritsu KEW 6315 Power Quality Analyzer
The Kyoritsu KEW 6315 is a high-performance, compact three-phase power quality and energy analyzer engineered for simultaneous power and power quality diagnostics. Compliant with IEC 61000-4-30 Class S, it measures voltage, current, active/reactive/apparent power, energy consumption, and harmonics up to the 50th order while capturing transient swells, dips, interruptions, and inrush currents.
Key Features
- Extensive Measurement Capabilities: The Kyoritsu KEW6315 Power Quality Analyser supports multiple wiring configurations, including 1P2W, 1P3W, 3P3W, and 3P4W. It measures voltage, current, frequency, power (active, reactive, and apparent), energy consumption, harmonics, power factor, inrush current, and other critical electrical values.
- High Accuracy and Wide Range: Voltage measurement ranges up to 1000V with ±0.2% accuracy, while current measurements are supported by multiple clamp sensors ranging from 50A to 3000A. Active power readings maintain high precision even under fluctuating load conditions.
- Advanced Data Logging and Memory: The Kyoritsu KEW6315 has 4MB of internal memory and SD card support of up to 2GB, so it can store large volumes of data for long-term analysis. The one-second display update period ensures near real-time feedback on system performance.
- User-Friendly Display and Interface: The Kyoritsu KEW6315 Power Quality Analyser features a 3.5-inch TFT color display with 320×240 pixel resolution, which provides a clear view of recorded data. USB and Bluetooth allow easy data transfer to PCs and mobile devices.
- Rugged and Portable Design: Compact in size (175mm x 120mm x 68mm) and weighing approximately 900g, the Kyoritsu KEW6315 is both portable and durable, suitable for fieldwork and demanding environments.
- Environmental Adaptability: Operates within a wide temperature range (0–45°C) and up to 85% relative humidity, making it ideal for various site conditions.
