ST40 Compact DIN Rail Mounted Energy and Power Quality Meter
The ST40 DIN rail energy meter is one of the smallest energy and power quality meters in the world. It was designed specifically for DIN rail installation where space is at a premium. The meter provides 0.2% class energy accuracy and advanced power quality features.
Advanced Revenue Meter
- ANSI C12.20 0.2 Accuracy Class energy measurement.
- Traceable watt-hour test pulse for accuracy verification testing.
- Utility block and rolling average demand.
- Transformer Line Loss and CT/PT Compensation.
- Line frequency time sync.
- Sealable voltage and current inputs.
Extensive Data Logging Capability
(V2 and Above)
- Three independent historical trending logs of 64+ parameters each.
- Anti-tampering system events log records actions in the DIN rail energy meter.
- Power quality log provides timestamped magnitude and duration of up to 2048 events.
- Limit alarms log records out-of-limit events for up to eight programmed limits, including voltage and current unbalance.
Power Quality Measurement
- Up to 512 samples per cycle waveform recording.
- Pre and post event waveform recording is provided.
