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.

supply:
Manufacturer: Carl Zeiss
Model: VWH 200/C 250 f-3b
Manufacturer P/N: 39 26 34 (also written as 392634)
Supported fluorescence lamps: HBO 200 W/4 L1, HBO 200 W/4 L2 and CSI 250W
Input voltage: 220 V – 240 V
Power rating: 900 VA

This power supply was supplied as standard with Zeiss Photomicroscope microscopes (commonly known as the Zeiss Phomi) whenever the microscope was equipped with an HBO high-pressure fluorescence illuminator (also referred to as a burner or lamp).

The same or very similar illuminators with identical electrical specifications were used in, among others:
- Zeiss Standard WL
- Zeiss Photomicroscope
- Zeiss Universal
- Zeiss Ultraphot
- such illuminators were also occasionally adapted for use with other microscope models, including those made by other manufacturers
Therefore, this power supply is suitable for all of the applications listed above.

Please note: the last photograph shows a dent in the housing. This does not affect the operation of the unit. Since the dent is located on the underside of the housing, it is not visible when the power supply is standing on a laboratory bench.

IMPORTANT: Always protect your eyesight when working with UV illumination. Never exceed the recommended service life of HBO high-pressure lamps. Always follow the operating instructions supplied with the fluorescence illuminator.

supply:
Manufacturer: Carl Zeiss
Model: NAG 2...12V 100W
Catalogue number: 39 25 85
Input: 100-110-120-127-220-240 V
Output: 12 V
Output power: 100 W
Power connector: separate computer-type power cable
Potentiometer: yes, smooth brightness adjustment

Designed for any microscope illuminator using a light source (lamp) rated at up to 100 W and operating at 12 V. It is most commonly used with external HAL 100 halogen illuminators (so-called Lampenhaus units), for example in reflected-light EPI illuminators.

This power supply can be used with illuminators and microscopes from any manufacturer. Here are several configurations verified in practice:
- compatible with the PZO Biolar DIC microscope fitted with the PZO OH-1 halogen illuminator, replacing the PZO ZM-100 or PZO ZH-100 power supply
- if the internal power supply in the base of an Olympus BH-2 BHS microscope fails, the original halogen illuminator can be powered using this external Zeiss power supply
- compatible with the large external halogen illuminator used for reflected-light EPI illumination on Carl Zeiss Jena Amplival Pol and Vertival microscopes
- also compatible with the Reichert Zetopan microscope equipped with the LUX-US 12 V 100 W halogen illuminator

Note – different manufacturers and different illuminators may use different pin spacing in their 12 V connectors. It may therefore be necessary to modify the connector in order to connect it to this Zeiss power supply.

supply:
Manufacturer: Carl Zeiss
Model: NAG 6V 20W stab.
Catalogue number: 45 84 15 - 9901
Input: 100-120-230-240 V
Output: 6 V
Output power: two outputs. It can supply either 2 × 10 W or 1 × 20 W
Power connector: separate computer-type power cable
Potentiometer: yes, smooth adjustment

This power supply has a maximum output power of 20 W and provides two outputs, allowing two 10 W illuminators to be connected and operated simultaneously.

However, it is a universal power supply and can be used with any microscope illuminator using a light source (lamp) rated at up to 20 W and operating at 6 V. Since most Zeiss microscopes use 6 V 15 W lamps, this power supply is suitable for virtually every microscope equipped with such illumination.

This power supply is most commonly used with microscopes employing 6 V 10 W halogen lamps, where both the transmitted-light illuminator and the reflected-light EPI illuminator are connected to the same power supply. Examples include:
- Zeiss D / DR / DRC / SV (Stemi) stereo microscopes
- Zeiss KF-2 biological microscope
- Zeiss ID2 inverted microscope

Special illuminators designed to work with this power supply were even manufactured for the Zeiss D / DR / DRC stereo microscopes:
- transmitted-light base "Zusatz für Durchlicht" with a 10 W halogen lamp
- auxiliary illuminators "Leuchte 10" / "Leuchte 10 S" with a 10 W halogen lamp
- vertical illuminator "Epileuchte" with a 15 W incandescent lamp

"Leuchte 10S" illuminators on a flexible arm, together with this particular power supply, are frequently used as a source of side reflected illumination for the Zeiss KF-2 biological microscope.

Examples of other microscopes whose 6 V 15 W illumination is compatible with this power supply:
- Zeiss Standard 16 / WL / GFL
- Zeiss Universal / Photomicroscope
- PZO Biolar
- PZO MST-130 / 131
- Carl Zeiss Jena Ergaval / Amplival
- Carl Zeiss Jena SM-xx
- this power supply can also be used externally to power the halogen illuminator of Carl Zeiss Jena Jenamed microscopes if the internal power supply fails (Jenamed uses a 6 V 20 W halogen lamp)

Note – different manufacturers and different illuminators may use different pin spacing in their 6 V connectors. It may therefore be necessary to modify the connector in order to connect it to this Zeiss power supply.

Description of this part for the microscope.

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.
