What Manta Test does
Manta Test Systems is a North American utility solutions provider specializing in protective relay testing equipment for electric utilities and the broader power sector. Founded in 1978 and headquartered in Marlborough, Massachusetts, the company was acquired by Doble Engineering Company in 2020, making it a subsidiary within Doble's portfolio of electrical testing solutions; Doble itself operates under ESCO Technologies (NYSE: ESE). The company is small, with 11–50 employees, and holds ISO 9001:2015 quality management certification.
The company's product line centers on the MTS-5100 All-in-One Relay Test System, a hardware platform featuring a direct front-panel interface that enables testing and calibration of protection and control relays, simulation of power-system phenomena, and verification of voltage, current, phase, and power transducers. Supporting offerings include file downloads for the product ecosystem, repair/RMA services, calibration, and protective-relay training courses. The underlying architecture is instrument-grade analog/digital test hardware rather than software-defined or AI-driven.
Manta's commercial motion is conducted almost entirely through Doble Engineering Company's enterprise field sales organization, with inbound sales routed to [email protected] and marketing distributed via Doble's website and YouTube channels. Revenue is generated predominantly through one-time equipment sales of the MTS-5100 series to power utilities and energy-sector customers, supplemented by recurring-adjacent calibration, repair, and training services. The company has not disclosed revenue, ARR, or unit volumes, and is not separately reported within ESCO Technologies' public filings.
