GW Instek GPM-83x0 and GPM-83x0-60 Series, Advanced Digital Power Meters Introduction
The GW Instek GPM-8320/8330 series expands with the new GPM-8320-60 and GPM-8330-60 models, designed for three-phase power measurements up to 60A direct current. With a 5" TFT display, harmonic analysis up to 50 orders, and DC-100kHz bandwidth, they represent the ideal solution for testing motors, power supplies, and high-power devices.
- Complete series: GPM-8320 (2 channels), GPM-8330 (3 channels) and new -60 models (direct current up to 60A)
- 5" TFT LCD display (800×480) for simultaneous waveform and parameter visualization
- Bandwidth: DC, 0.1Hz ~ 100kHz with 300kHz sample rate
- Wiring configurations: 1P3W, 3P3W, 3P4W, 3V3A
- IEC 61000-4-7 compliant harmonic analysis (50/60Hz)
- Interfaces: RS-232C, USB device/host, LAN, optional GPIB and Digital I/O
Target Applications
- Production testing for power supplies, transformers, motors
- Energy efficiency measurements on electrical devices
- Power quality analysis and harmonic distortion
- Research and development laboratories, quality control
New: GPM-8320-60 and GPM-8330-60 Models
- Direct current up to 60A: Eliminate the need for external current transformers
- Extended range: From 1A to 60A with CF=3, from 0.5A to 30A with CF=6/6A
- Same form factor: Identical dimensions to standard models (132×220×402.5mm)
- Cost savings: Significant reduction in current transformer costs
