Product catalog summary

Introduction
Trafox has developed new high-quality Medical Isolation Transformers, specifically the KKSA and KKS series, designed for use in healthcare settings such as hospitals and clinics. These transformers ensure electrical safety in medical equipment and devices.

Key Features

Low inrush current, typically under 3.5 times the nominal current (In), eliminating the need for separate inrush peak limiting devices.
Lower primary fuse ratings compared to other medical transformers, allowing for smaller copper cross-section wires and cost savings in hospital installations.
Low leakage currents and no-load losses, contributing to energy efficiency.
Long lifetime design with high-temperature class insulations.

Technical Specifications

Available in 4kVA, 6.3kVA, 8kVA, and 10kVA models.
Rated frequency: 50-60Hz; Rated input voltage: 230V; Rated output voltage: 230/115V.
Max inrush current: 3.5x In; Primary fuse (slow): 20A to 50A depending on model.
Leakage current: 0.2mA to 0.4mA; No load input current Io/%: <3%.
Short circuit voltage uk: <4.3% to <3.7%; Efficiency: 95.7% to 96.8%.
Noise level at 100% load: <35dB; Ambient temperature: 45°C.
Insulation materials temperature class: F; Degree of protection: IP00/IP21.
Standards: IEC/EN 61558-1, IEC/EN 61558-2-15, CE, RoHS.

Applications and Compliance

Suitable for hospital operating theatres and intensive care units, compliant with medical location norms of group 2 (HD60364-7-710, DIN VDE0100-710, SFS6000-7-710).
Features include monitoring of isolation, temperature, loading, fault location detection, residual current, and PE conductor continuity.
Equipped with automatic voltage changeover switching device, remote control, Ethernet connection, and fault memory logging.

Mechanical Specifications

Detailed dimensions and weights provided for each model (KKS and KKSA series).
Available accessories include shelves for transformers.

FINDING SOLUTIONS TO ENSURE WELL-BEING We have been involved in developing the field of Healthcare for decades and we are extremely proud of our part. As a result of collaboration with several pioneering companies in the field of Healthcare, numerous Trafox solutions are currently used in hospitals and clinics in various medical equipment and devices ensuring and monitoring electrical safety. New high quality Trafox Medical Isolation Transformers have a very low inrush current, typically under 3,5x In. Because of this, there is no need for separate inrush peak limiting devices. The primary fuses can be rated lower than with other medical transformers. The installation can be done by wires having a smaller copper cross section. This will increase the total savings in hospital electricity installations. The Trafox Medical Isolation Transformer has also been designed so that the leakage currents and no-load losses are at a low level. These transformers do have also long lifetime design with high temperature class insulations. Medical Transformers SINGLE PHASE, TYPE KKSA, KKS
