Product number: TH3431
Description
The TH343X/TH344X series are modular digital power meters with 1 to 4 measuring channels, 7″ touchscreen, true RMS AC/DC measurement, various winding and phase modes as well as optional harmonic analysis. They are suitable for automated test benches and laboratory applications in industry and research.Features
- 7″ TFT touchscreen (800×480) with multilingual GUI and numerical input for convenient operation and fast parameterisation
- True RMS measurement of voltage and current (AC/DC) with high accuracy (±0.15 % reading + 0.2 % range) and wide frequency range (DC to 100 kHz)
- Flexible winding and phase modes: single-phase 2-wire, 3-wire, three-phase 3 and 4-wire and special 3V3A configurations (depending on model)
- Automatic and manual measuring range: voltage 1-600 V (15/30/60/150/300/600 V), current ranges vary per model (micro to ten ampere ranges)
- Energy integration: Counter up to 99,999 kWh and time measurement up to 9,999:59:59 h:m:s for long-term measurements
Harmonic analysis (depending on model): 2nd-50th order with list and histogram display for power quality checks - Waveform display (voltage/current) for visual signal testing and PLL synchronisation for precise measurements
- Comparison and bin functions with programmable relay outputs (PASS/FAIL) and acoustic signal for automated test sequences
- Interfaces: RS232C/RS485 (optional), USB host/device, LAN, HANDLER port for PC control and integration setup; SCPI-compatible
- Robust, compact housing with integrated memory (USB stick) for firmware upgrade and log files; operation at 200-240 VAC, 0-40 °C, ≤80 % RH
Applications
- Energy and performance tests on household appliances (TV, refrigerator, air conditioning, washing machine) and industrial systems
- Motor and transformer testing, power supply and power electronics characterisation
- LED and lighting tests, photovoltaic/EV charger measurements in research and production
- Automated production test benches with pass/fail output, handle integration and data acquisition
- Laboratory and development environments: Prototype testing, long-term measurements, waveform and harmonic analysis for power quality tests
