Overview

Features & Benefits

The Seeker provides advanced power quality recording with integrated wireless communication and digital I/O in a small weatherproof, line-powered device. Designed for investigative work, smart grid distribution monitoring, and remote control applications, the Seeker is a one size fits all PQ solution.

Cloud-based Recording

The Seeker continuously streams PQ data to cloud-based PQ Canvass. Use a web browser to analyze the latest data instantly, without downloading.

Control Options

Use the internal dual Form C relays to control distributed generation or other equipment through SCADA or automatically based on measured values. Two isolated digital inputs provide status or other equipment monitoring.

Communication Options

The Seeker includes several communication options:

• Wi-Fi
• Bluetooth Low Energy
• LTE Cellular Modem
• Ethernet
• USB connection is standard on all Seekers

SCADA Compatibility

A full DNP and MODBUS interface over Wi-Fi, Cell or Ethernet exposes all PQ measurements and I/O control functions.

Easy to Install

The Seeker’s small weatherproof enclosure contains the AC power supply, wireless communications, relays, and PQ monitor. No external enclosure, power supply, or communications device is needed.
