For test engineers and system integrators, a PDU equipped with our advanced meter adds real-time visibility into power, energy, and power-quality behavior at the rack or system level.
The meter is designed for straightforward integration with test stands, automation systems, and host applications through Modbus and the built-in web server.
It combines three-phase measurement, energy accumulation, power-quality analysis, alarm handling, onboard data logging, and network communications in a single platform, with a high-visibility LCD for continuous local readout.
What can this meter do for you?
For applications that require more than basic current and voltage monitoring, this meter adds the data depth needed for validation, troubleshooting, and automated system monitoring:
- Real-time true RMS measurement of current, voltage, power, energy, and other key electrical parameters.
- Power-quality visibility including voltage and current unbalance, total harmonic distortion (THD), and individual harmonics.
- Up to four simultaneous onboard data logs with 8 MB of memory and export in CSV or JSON format.
- Configurable alarms for event detection, status monitoring, and triggered logging.
- Multiple access methods for data retrieval and system integration, including the embedded web server, FTP/SFTP, HTTP/HTTPS, and NTP-based time synchronization.
- Optional I/O expansion for capturing additional digital states such as breaker position or external status signals.
More Reasons to Use an AC General PDU with Power Meter
In test environments, correlating power-quality events with system behavior can help isolate intermittent failures, explain unexpected results, and verify input-power conditions during validation. With integrated logging and alarms, this meter supports workflows such as:
- Monitor voltage dips (sags) and swells to identify input-power disturbances that may affect test repeatability, equipment behavior, or system uptime.
- Track total harmonic distortion (THD) as part of power-quality verification for sensitive loads and troubleshooting workflows.
- Monitor phase unbalance to detect supply issues that can influence three-phase equipment performance and measurement stability.
- Characterize power quality over time and use the resulting data to guide corrective action or validate mitigation steps.
Can AC General customize the PDU to better fit your needs?
We specialize in configurable PDUs and can adapt both the panel and meter to match application requirements, including non-standard line frequency such as 400 Hz, alternate service voltages such as 480 VAC, and other system-specific integration needs.
