HIOKI PW3360-20 Clamp-On Power Logger | Single-phase to 3-phase 4-wire, voltage / active power ±0.3% rdg. ±0.1% f.s., QUICK SET wiring guide (harmonic analysis on PW3360-21)

HIOKI PW3360-20 Clamp-On Power Logger: Single-Phase to Three-Phase 4-Wire Power Recording

Overview

The PW3360-20 uses current clamps to measure and log voltage, current, power and energy on single-phase to three-phase 4-wire circuits over long periods, for energy-saving diagnostics and equipment power surveys. The PW3360-20 is the English-version main unit and has no harmonic analysis; for harmonic analysis (up to 40th order), choose the PW3360-21. Current clamps are sold separately.

Key Specifications

• Wiring: Single-phase 2-wire (1 / 2 / 3 circuits), single-phase 3-wire, three-phase 3-wire, three-phase 4-wire (1 circuit), or current only 1–3 ch.
• Voltage: Rated 600 V AC, effective range 90.00–780.00 V.
• Accuracy (1 year): Voltage ±0.3% rdg. ±0.1% f.s.; active power ±0.3% rdg. ±0.1% f.s. + current clamp accuracy (PF = 1).
• Setup: QUICK SET screens guide wiring, with a wiring check function.

Applications

• Power consumption surveys in factories and buildings, and before/after comparison of energy-saving improvements.
