1130 - Thumbnail photo showing this microscope part. Carl Zeiss Jena Jenaval / Jenapol microscope internal power supply and electrics - thumbnail [ 99687 ]	SERMIK_ID number under which this microscope part is placed in the database. 99687	Carl Zeiss Jena Jenaval / Jenapol microscope internal power supply and electrics	The name of this microscope part. Carl Zeiss Jena Jenaval / Jenapol microscope internal power supply and electrics	Description of this part for the microscope. Internal power supply (transformer and electronics) with brightness control potentiometer for Carl Zeiss Jena Jenaval and similar microscopes. This is a ... transformer assembly installed inside the microscope base. It converts an input voltage of 110–240 V into a 6 V output with a maximum power of 25 W. It is intended to power a halogen lamp house. An example of this lamp house can be found in this database under item number 99693. This is not the power supply for the 50W/100W reflected-light lamp housing used on the Carl Zeiss Jena Jenavert. It is also not the power supply for the fluorescent lamp houses used on the Carl Zeiss Jena Jenalumar. Compatible with the following microscope models: - Carl Zeiss Jena Jenaval - Carl Zeiss Jena Jenalumar - Carl Zeiss Jena Jenapol - Carl Zeiss Jena Jenavert If you only need one component from this assembly—for example the transformer, one of the electronic circuit boards or just the potentiometer used to adjust the lamp brightness—please contact us by email or through our social media channels. This complete assembly may be useful for solving the following microscope problems, among others: - if the microscope illumination no longer works because of a faulty power supply. This may be caused by mains voltage surges, ageing electronic components or damage resulting from incorrect modifications (for example, conversion to LED lighting) - if the illumination works but the brightness can no longer be adjusted because the potentiometer is worn out or defective Originally, the complete power supply assembly (transformer, electronic circuit boards and wiring) is installed inside the microscope base, and it is offered here exactly in that configuration. How can it be used? - the electrical components can be removed and used as spare parts to repair a damaged power supply - the complete microscope base can be transplanted to another microscope (please note that it does not include any optical components) An interesting DIY modification is to leave the power supply in the base offered here and then place the microscope on top of that base. This effectively raises the microscope while also providing an integrated power supply for a second lamp house. Names, descriptions, terms, and search contexts under which this part is searched.
