About Polyamp

Polyamp is specialized in power convertion and underwater electromagnetics signatures 

With our own design and manufacture capacity we provide AC/DC & DC/DC Converters in 19" modular base 1/2 & 19" rack modules 2U, 3U  and 6 U. Inputs from 12 Vd.c. to 400 Vd.c. with outputs from 5 to 120 Vd.c. High reliability and long life is our signum. We also make customised design either extension from the standard range or specific design.
We also distribute:
Delta Elektronika range of labb power supplies from 150 W to 900 kW 1500 V max voltage.
Enedo|PowerNet AC/DC 50W to 3 kW modular and DC/AC range 1500 - 3000 W modular for telecom, industrial and train applications.

Electromagnetic signature systems
From 1980-ties we have delivered fully Digitally controlled Degaussing amplifier to the Swedish Navy. Around mid 1990-ties we became an international complete system supplier of Degaussing systems for naval vessels. From Drones to Carriers and submarines.
SWECADE is our Magnetic modelling and coil design tool which also include , measuring and analyze of vessels signatures and storing the individual signature vessels performance. 

We provide an Underwater Electric Field sensor made in Carbon Fibre (CF) measuring UEP(Underwater Electric Potential). Actually ULFE/ELFE signatures down to 1 nV/m(RoothHz) with frequency range 10 mHz to 5000 Hz. 

Using this electromagnetic knowledge we supply multisensor underwater platforms UMISS that measure underwater Magnetic, Electric, pressure and optionally Accoustics signatures.. Those are used for Navy vessels ranging or recognisance, harbour protection etc.
We also have a light Electromagnetic Mine Sweep concept, towed by ROV type of vessels. With less than 25 kW we simulate a realistic signature up to Frigate size vessel, with or without onboard Degaussing system.
