What Querom Elektronik does

Querom Elektronik GmbH is a privately held German power-electronics developer and product manufacturer founded in March 2017 in Geisenhausen, Lower Bavaria. The company specializes in customized DC/DC converters in the 1-10 kW power range, with input voltages up to 1,000 VDC, alongside battery management systems, charging technology, and communication interfaces (CAN, CAN-OPEN, Modbus, RS232, I2C, Ethernet) for Industry 4.0 integration. Two proprietary product families anchor the catalog: the DDL series of non-isolated bidirectional buck/boost converters (48V and 96V variants at 3-5 kW, ~97% efficiency, with parallel-operation capability) and the DDH series of galvanically isolated high-voltage converters handling up to 900 VDC input for safe coupling of high-voltage DC buses to 24V control levels.

The company serves enterprise customers across intralogistics and AGV/AMR robotics, hydrogen and energy technology (including electrolyser and fuel-cell integration), construction machinery and municipal vehicle electrification, industrial DC grids, and stationary energy storage (Li-ion and redox-flow). Named references include Einhell, DRÄXLMAIER Group, Gebhardt Intralogistics Group, Gridstore, Enapter, Deutronic, REVIVE Automotive, the German Aerospace Center (DLR), ONOX, and GEOMAR Helmholtz-Zentrum für Ozeanforschung, with customer and partner activity spanning more than 20 countries.

Querom earns revenue through two streams: direct sales of its own DDL/DDH converter products and customer-specific development services covering DC/DC converter engineering, BMS and charging technology, and communication-interface integration. GTM is engineering-led and sales-direct, supported by an international distribution partnership with CAPCOMP GmbH (since May 2024) and manufacturing executed by Incap Electronics Germany GmbH (formerly Lacon Group) under an ODM/EMS arrangement. The company is DEKRA ISO 9001:2015 certified, a member of the Open DC Alliance (ODCA) and the Bavarian Power Electronics Cluster, and operates with approximately 12 employees as a subsidiary within the Incap Electronics Germany group.
