What Polyamp does
Polyamp AB is a Swedish private company founded in the late 1960s, headquartered in Sollentuna with manufacturing operations in Åtvidaberg. The company operates two divisions. The Systems Division delivers underwater electromagnetic signature management solutions for naval vessels, including degaussing systems capable of neutralizing 90-95% of magnetic signature, UMISS multi-influence sensor platforms, UEP/ELFE carbon fiber electrode sensors, the SWECADE software suite for signature modeling and analysis, and rapidly deployable magnetic signature measurement ranges. The Systems Division serves Swedish and international naval forces, with the Swedish Navy as an anchor customer since the 1980s and international naval contracts since the mid-1990s. Equipment is delivered through direct enterprise sales subject to defense export controls.
The Power Division designs and manufactures DC/DC converters (PSC, PM, PU, PC series spanning 32W to 2000W) for military, marine, telecom, railway, and heavy industrial applications, alongside AC/DC power supplies and DC/AC inverters. Polyamp also distributes Delta Elektronika lab power supplies (150W to 900kW systems), Enedo AC/DC and DC/AC products, and Inission Power solutions through its own sales channels. The Power Division reaches customers through a global reseller network in 18 countries and direct quotes for custom configurations.
The company's revenue model is hardware sales complemented by 24/7 service and support, with pricing conducted via custom quotation and multi-year contracts. Reliability is a core value proposition, with demonstrated metrics including 3.3 million hours MTBF and close to 100% on-time delivery. The company is ISO 9001:2015 certified, holds patented carbon fiber electrode sensor technology, and has over 50 years of accumulated expertise in power conversion and underwater electromagnetics.
