HIOKI PW3336 / PW3337 Power Meter | PW3336 2 ch, PW3337 3 ch (incl. 3-phase 4-wire), DC and 0.1 Hz–100 kHz, current direct input 65 A

HIOKI PW3336 / PW3337 Power Meter: Multi-Channel AC/DC Power Measurement

Overview

The PW3336 (2 ch) and PW3337 (3 ch) measure voltage, current, power and harmonics on single-phase to three-phase circuits. The PW3336 supports single-phase 2-wire, single-phase 3-wire and three-phase 3-wire; for three-phase 4-wire, choose the PW3337. Bandwidth is DC, 0.1 Hz–100 kHz; current can be input directly from 2 mA to 65 A, and external current sensors extend measurement to AC 5000 A.

Key Specifications

• Active power accuracy: DC ±0.1% rdg. ±0.1% f.s.; at 45–66 Hz ±0.1% rdg. ±0.05% f.s. (input below 50% f.s.), ±0.15% rdg. (input 50% f.s. or above).
• Input: Voltage 0.15–1000 V AC/DC; current direct 2 mA–65 A AC/DC.
• Harmonics: Up to 50th order (IEC 61000-4-7).
• Interfaces (by suffix): All models have LAN and RS-232C as standard (no USB); -01 adds GP-IB; -02 adds D/A output; -03 has both GP-IB and D/A (GP-IB on -01 / -03).

Applications

• Power and efficiency measurement of three-phase motors, inverter equipment and power supply products.
