The Dossena 9TH series isolation transformers are high-quality, dry-type units specifically designed for medical IT systems, where electrical safety and reliability are critical.

Built with copper windings in a robust two-column construction, these single-phase transformers provide galvanic isolation between the primary and secondary circuits, protecting both patients and sensitive equipment from electrical faults.

These models include PT100 temperature sensors for continuous thermal monitoring, making the 9TH series a dependable and compliant choice for hospital and medical facility electrical installations.

EVO by Dossena is a dedicated LCD touchscreen datalogger and control interface specially developed to manage devices on a Modbus RS-485 network. It features a large, intuitive, easy-to-use, and multilingual display that acts as a centralized hub for monitoring and controlling connected equipment.

Capable of handling up to 20 Dossena-branded devices—or up to 10 devices with fault-location functionality—the EVO screen displays

real-time status, key measurements, and active alarms from the network, ensuring operators stay informed of system conditions at a glance.

EVO also integrates a web server, enabling remote access: you can view the Modbus network status and download log files via a browser by accessing the device’s IP address. Additionally, multiple EVO units can be grouped into a centralized cloud-based dashboard through Dossena’s optional Corvina service, facilitating global access from PCs or mobile devices.

The Dossena 9 PSR3 Remote Control Panel is a compact, wall-mountable interface designed to work with the SRI3/H2 insulation monitoring systems, primarily in medical IT-M electrical installations.

Acting as a remote indicator, it mirrors the main unit’s surveillance, alarm, and warning signals, allowing personnel to monitor system status from a distance. Its installation is straightforward, requiring only three communication wires, and it is available in both flush-mount and

surface-mount versions to suit different environments. Built with durable, self-extinguishing plastic housing and available in 2-DIN or 3-DIN formats, the 9 PSR3 combines safety, reliability, and convenience, making it ideal for demanding medical and technical settings.

The 9SRI3 Series devices form a modular and scalable family of Dossena insulation monitors, specifically designed for medical-grade IT-M systems. The H2FL6 model offers integrated fault location across six branches with RS-485 communication, while the H2INJ variant adds intelligent signal injection to enhance fault localization.

The H2FL12 and H2FL18 expansion modules further extend monitoring capacity to cover 12 or 18 additional circuits, enabling comprehensive tracking of insulation integrity across large-scale electrical systems.

The Dossena TAB1/50 is a robust, low-voltage, closed-core current transformer engineered for sealed, through-bar or cable installations. Its enhanced primary aperture and flexible mounting methods enable effortless integration, while Faston secondary terminals support secure, tool-friendly connectivity.

Constructed with fire-resistant thermoplastic, and tailored for precision in medical-grade IT-M systems, it’s a reliable choice for safeguarding and measuring current in critical electrical networks.

The Dossena 9TD15 Toroidal Current Transducer is a compact, split-core sensor tailored for medical IT-M insulation monitoring systems.

Supplied with connection cabling and built with compatibility in mind for SRI3/H2 devices, it simplifies installation and ensures reliable performance

Compliant with relevant IEC standards, and with practical usage guidelines recommending shielded, centrally routed conductors and EMI-aware placement, the 9TD15 is a precise, practical choice for safeguarding critical medical electrical networks.
