EQ Wave v1

The EQ Wave v1 is a CPOW power quality sensor designed for permanent installation in electrical panels. It captures gapless, high-resolution voltage and current waveforms and streams them to an EQ Gateway for storage and analysis.

Key Characteristics

• Measurement: 3-phase voltage (up to 600V RMS) + 4 current channels via external transducers or Rogowski coils
• Resolution: 24-bit, 32 ksps, 7-channel simultaneous-sampling delta-sigma ADC
• Two-stage isolation: Fiber optic networking + internal isolation barrier (3 kV)
• Self-powered: AC input (85–528V) or DC input (4.5–36V, v1.2)
• Industrial: -40°C to +70°C, fanless, rugged polycarbonate enclosure
• Data streams: Continuous CPOW waveforms (port 1534) + power metrics (port 1535) over TCP
• Network: 100Base-FX over plastic optical fiber (POF) via Firecomms OptoLock® connector
• Processor: ARM Cortex-M4 with FPU, real-time operating system with TCP/IP networking

Platform Integration

The sensor connects to an EQ Gateway running EQ Coherence for gapless data recording, long-term storage, APIs, and real-time visualization. EQ Syntropy adds optional AI analytics.

Hardware Versions

• v1.0 (2023): Initial prototype with core measurement and streaming
• v1.1 (2024): Dual high-voltage resistor divider for improved safety; timing-optimized GNSS receiver footprint
• v1.2 (2025): Current pilot version. Expanded voltage range (600V), supercapacitor backup power (~8 seconds), improved analog conditioning, DC power input (4.5–36V)

All v1 hardware versions share the same firmware and network interface.

Optional Hardware Features

Factory-configurable options — order with the matching suffix; see the datasheet for capability detail and lead time:

• GNSS receiver (-G) — Precision time synchronization. Not populated on standard units.
• Onboard storage (-SD) — microSD-based local buffering of CPOW and power metrics through gateway or network interruptions, with backfill on reconnect.

Core hardware (ADC, MCU, 100Base-FX optical networking, isolation architecture, power supply options) is covered in the datasheet.

Current Limitations (v1 Firmware)

• Fixed IP: 192.168.10.10, no DHCP
• No remote firmware update: v1 requires physical access (factory RMA) for firmware changes

EQ Wave v2, the certified production version, is in development. See eq.systems/platform/eq-wave, or contact [email protected] to discuss upcoming capabilities.
