# Part name: Carl Zeiss Jena Jenamed microscope power supply and fine focus block # Original page URL: https://www.microscopeparts.eu/part/carl-zeiss-jena-jenamed-microscope-power-supply-and-fine-focus-block-99461 # Part manufacturer: Carl Zeiss Jena # Full manufacturer name: VEB Carl Zeiss Jena DDR (former East Germany) # Other names of this manufacturer: - ausJena - aus Jena These are names commonly used to refer to this manufacturer of microscopes and microscope parts, even if they are not official. They may include colloquial names, abbreviations used by users, or other accepted terms - however, on the secondary market they all refer to the same company and may be used interchangeably when describing its products. # Belongs to category: Power supplies (transformers) # Description and specifications: Internal power supply (transformer and electronics) and fine focus mechanism (micro-adjustment) for Carl Zeiss Jena Jenamed microscopes. Compatible with the following Carl Zeiss Jena microscopes: - Jenamed Variant - Jenamed Cytology - Jenamed Hematology - Jenamed Histology This is a large module that is mechanically integrated, although it can be disassembled into smaller parts. However, if replacement becomes necessary, it is usually more convenient to replace the complete assembly. For this reason it is presented and offered here as a complete unit. The assembly shown here includes: - internal power supply electronics (potentiometer, transformer, etc.) - fine focus mechanism (micro-adjustment) If you need any individual component from this assembly, for example the transformer, a specific electronic board, only the brightness control potentiometer, or only the fine focus mechanism itself, please contact us by email. Please note: - the power supply is compatible with every Carl Zeiss Jena Jenamed microscope model, including Jenamed 2 and Jenamed Fluorescence - however, the complete fine focus mechanism assembly does NOT fit Jenamed-2 and Jenamed Fluorescence, although some smaller components of the fine focus mechanism are identical across all Jenamed microscope models This complete assembly may be required to solve, among others, the following problems in Carl Zeiss Jena Jenamed microscopes: - when the microscope illumination does not work due to a defective power supply. This may be caused by mains voltage surges, ageing electronic components, or damage resulting from improper modifications (for example LED conversions) - when the illumination works but brightness adjustment does not function because of a defective or worn potentiometer - when the fine focus mechanism does not work properly, for example when the objective turret does not move upward or slowly drops by itself It is very important to note that the internal power supply used in Carl Zeiss Jena Jenamed microscopes converts 220-240V mains voltage to 6V with a maximum power output of 25W. This power supply has the same specifications as those used in Carl Zeiss Jena Jenaval and Carl Zeiss Jena Jenalumar microscopes. If you own one of these microscopes with a defective power supply, any qualified electronics technician can transfer the electronics from a Jenamed microscope. # Examples of use - as a service component for replacement of the complete assembly - if you need any individual part from this assembly to repair your microscope - if you wish to transfer the electronics to Carl Zeiss Jena Jenaval or Jenalumar microscopes - several example applications are described above # Removed from microscope: Carl Zeiss Jena Jenamed # Also compatible with the following microscopes: Carl Zeiss Jena Jenamed # Names, descriptions, terms, and search contexts under which this part is searched. - Carl Zeiss Jena Jenamed microscope repair parts - Carl Zeiss Jena Jenamed Mikroskop Netzgerät - Jenamed Mikroskop Trafo und Potentiometer - Jenamed Mikroskop Fokussier-Feintrieb - Carl Zeiss Jena Jenamed microscope fine focus - Jenamed microscope transformer - Jenamed microscope electronic - Jenaval microscope electronic - Jenaval Mikroskop Netzteil - zasilacz Carl Zeiss Jena Jenamed - Beleuchtung im Jenamed Mikroskop funktioniert nicht - Netzteil im Jenamed Mikroskop defekt - Netzteil im Jenamed Mikroskop durchgebrannt - illumination not working in Jenamed microscope - Jenamed microscope power supply failure - burned power supply in Jenamed microscope - defective power supply in Jenamed microscope - Carl Zeiss Jena buy spare parts # Related URLs: - Markdown po polsku: https://www.serwismikroskopowy.pl/part/99461.md - Markdown auf Deutsch: https://www.mikroskopteile.de/part/99461.md - Gallery of all photos of this part: https://www.microscopeparts.eu/gallery/99461-carl-zeiss-jena-jenamed-microscope-power-supply-and-fine-focus-block - Media manifest of this part (photos + videos, for AI/RAG): https://www.microscopeparts.eu/part/99461.media.md - Representative photo: https://www.microscopeparts.eu/photo/carl-zeiss-jena-jenamed-microscope-power-supply-and-fine-focus-block-99461-2 - Representative video: https://www.microscopeparts.eu/play/99461-1 - Other parts from category Power supplies (transformers): https://www.microscopeparts.eu/power-supplies-transformers - More Power supplies (transformers) removed from microscope Carl Zeiss Jena Jenamed: https://www.microscopeparts.eu/power-supplies-transformers/from/carl-zeiss-jena/jenamed - More Power supplies (transformers) compatible with microscope Carl Zeiss Jena Jenamed: https://www.microscopeparts.eu/power-supplies-transformers/for/carl-zeiss-jena/jenamed - More Power supplies (transformers) removed from microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/power-supplies-transformers/from/carl-zeiss-jena - More Power supplies (transformers) compatible with microscopes Carl Zeiss Jena: https://www.microscopeparts.eu/power-supplies-transformers/for/carl-zeiss-jena # Important information: Database Description: Technical microscope parts database based on years of practical service experience.
