Applications of transformers in industrial and commercial control circuits

ktc transformers are used in a wide range of industrial and technical applications. They provide defined secondary voltages, ensure a stable supply for control and logic circuits and offer reliable galvanic isolation between mains and device circuits. In areas such as mechanical engineering, automation technology, control cabinet construction, robotics, railroad technology, laboratory environments, medical technology, combustion systems, internationally operated installations or transformers with special approvals, the individual series support voltage levels that are precisely adapted to the respective requirements. The technical design addresses continuous load capacity, thermal stability, variable input conditions and defined insulation distances, resulting in high operational reliability and consistent function in different operating environments.

Medical technology

Devices in medical technology require stable, electrically isolated supply voltages. The solutions from ktc GmbH meet these requirements with defined insulation values and high operational reliability.

Precise supply of small control circuits

Medical control circuits require a constant secondary voltage with minimal fluctuations. The device versions from ktc provide this stability even for sensitive components such as pump units or diagnostic systems. The decisive factor is the clean separation between the mains and device circuits, which minimizes interference currents and enables a reliable supply of voltage.

Galvanic isolation in accordance with medical safety requirements

Isolation plays a central role in medical applications. The transformer technology from ktc ensures defined isolating distances and prevents unwanted couplings. This fulfills safety-related requirements that are necessary for devices used in close proximity to patients or in sensitive applications. IEC 60601-1, for example, is a relevant guideline here.

Supply of medical devices with varying input conditions

Mobile medical devices often face changing input conditions. Ktc series are designed for these environments and generate reliable output voltages regardless of regional grid differences. This supports stable device operation in both stationary and mobile applications.

Systems with international mains voltages

Machines and systems are operated worldwide and require defined voltage levels for power and control. The designs from ktc GmbH address these requirements both in the control cabinet and in housings provided with application-specific equipment.

Voltage adjustment in the control cabinet with combined power and control supply

In many industrial machines, international mains voltages have to be converted to a defined system level. The transformer solutions from ktc handle both the adaptation of three-phase input voltages in the control cabinet, for example from 480 V to 400 V, and the provision of single-phase control voltages. The combination of power and control circuit supply within one system reduces interfaces and enables a consistent voltage architecture for machines that are used worldwide in different network environments.

Use in separate enclosures for transforming standard local networks to machine voltages

For applications outside the control cabinet, housing solutions are available that transform standard local power supplies – for example 400 V – into the voltage levels required for the machine, such as 200 V. In these systems, additional peripheral devices are often supplied, for example via integrated 230 V sockets. The design allows different loads to be operated in parallel without affecting the stability of the primary machine supply.

Expandable systems with circuit breakers, meters and function-specific modules

ktc’s enclosure variants offer space for additional technical components such as circuit breakers, electricity meters or modules for special applications, including extinguishing systems in environments with oil-based lubrication. The integration of these elements supports a uniform electrical infrastructure and enables compact complete solutions for systems that use international mains voltages and also require supplementary functions.

Railroad systems require transformers that provide defined voltage values, work reliably under extreme environmental conditions and meet safety requirements. The technical designs from ktc GmbH take these requirements into account in outdoor areas, on the rail, in adjacent infrastructures and in accordance with DIN EN 50125.

Use on switch and signal systems with special environmental requirements

Outdoor railroad applications require robust transformers that are used in switching and monitoring devices on switch systems or in signaling systems. The devices from ktc meet increased requirements in terms of temperature range, humidity and weather conditions. The design ensures stable secondary voltages despite changing climatic conditions and mechanical loads, which are common in track systems.

Isolating transformers for voltage stabilization and grid decoupling on the rail

Switch cabinets in which isolating transformers for voltage stabilization and grid decoupling are integrated are located directly on the rail. These designs from ktc GmbH support the safe operation of railroad infrastructure by providing defined isolation distances and reducing disruptive network feedback. The technology addresses the requirements of safety-critical railroad control and auxiliary circuits.

Compliance with Deutsche Bahn specifications including shock, vibration and climate tests

For use in railroad applications, transformers must meet specific Deutsche Bahn requirements. These include defined tests for shock, vibration and climate, which ensure that the devices work reliably even under mechanical and thermal stress. The designs from ktc are designed to meet these requirements and thus support the resilient and standard-compliant operation of railroad equipment.

The transformer solutions from ktc provide stable secondary voltages for control circuits, sensors and drive interfaces, thereby supporting the functional reliability of robot-supported production processes.

Isolation between power level and sensitive control electronics

In robot systems, power components and sensor units are often located close together. The designs from ktc work with defined insulation properties that reduce interference from the drive area and protect sensitive control and measurement circuits. This contributes to the repeat accuracy of the robot movements.

Resistance to dynamic loads and varying operating conditions

Robotics applications generate changing load conditions, cyclical stresses and sometimes increased ambient temperatures. Transformers from ktc are designed for these operating profiles and deliver constant voltage values even with fast clock cycles, pulse-like control and changing operating conditions. This supports the trouble-free and predictable use of robotics in industrial production environments.

Automation technology

Automated systems require stable voltage levels and robust insulation between the power and control levels. The series from ktc precisely address these technical requirements.

Supply of sensors and actuators

Sensor and actuator modules require a constant supply voltage to ensure reproducible switching and measuring processes. The technology from ktc delivers these values even under continuous thermal stress and changing loads.
