What Bontronic control technology does

Bontronic Steuerungstechnik GmbH, operating under the brand BONTRONIC, is a German designer and manufacturer of electrical and electronic equipment for industrial integration, headquartered in Troisdorf, Germany. The company operates in two primary modes: Original Design Manufacturing (ODM) for customer-specific electronics development covering hardware design, software programming, prototyping, qualification, and series production; and Electronics Manufacturing Services (EMS) for mass production subcontracting including SMD lines, wave soldering, AOI inspection, and electrotechnical cabinet cabling. Its proprietary product portfolio includes the Voltage Metering Amplifier (VMA), phase sequence relays (PFR3, PFR690, PFW2, PFW2-2-480, PFW3), time delay relays (TRT3, TRT3F, ZR4), and monitoring modules (NAG series, LKB, GTR, BT2), complemented by distribution of Zelisko transformers and sensors. Products are designed for 15-20+ year operational lifecycles and meet IEC 61850, IEC 61869-2/11, EN 1808, EMC, and functional safety standards.
