3-Phase 4-Wire Portable Energy Loggers for Energy Audits and Energy Conservation
HIOKI Clamp On Power Meters are multi-channel power measuring devices utilizing clamp sensor input to accurately and safely measure power on single-phase to three-phase lines. The PW3360-20 and PW3360-21 monitor power demand and other power parameters to aid in energy audits and validate energy saving measures.
• CLAMP ON POWER LOGGER PW3360-20 (Main unit only)
• CLAMP ON POWER LOGGER PW3360-21 (Harmonic analysis model)
Note: At least one optional current sensor is necessary to measure current or power parameters. To store measurement data, use only the guaranteed SD cards sold by HIOKI.
Supports single to three-phase, 4-wire circuits
• Measure up to 780V with a 1000V display range
• Simultaneously measure up to three single-phase, 2-wire circuits (in the same power system)
• Broadly applicable for many jobs, including leakage current measurement (An optional clamp-on leakage sensor supports measurements as low as 50 mA)
• Store months of data on SD cards
• The QUICK SET function guides you in making the right connections
• Choose PW3360-21 for harmonic measurements up to the 40th order
