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.

220V - 240V
Output: 8V
Output power: 20W
Power plug: European flat plug
Potentiometer: yes, smooth brightness adjustment

Designed for:
- Lomo OI-21 illuminator
- Lomo OI-35 illuminator
- illuminator used with MBC-9 and MBC-10 stereo microscopes

Also compatible with older black Lomo microscopes:
- MBB-1
- MIN-8
- EPI reflected-light illuminators, including those used with the Lomo METAM and Lomo MMU-3
- and many others

Some older Lomo microscopes (for example, the MBC-1 and MBC-2 stereo microscopes) may use different connectors, but they use the same Lomo 8V 20W BA15d lamps.

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.

Leica DM LD controller:
Model: Leica DMLD (also written as: DM LD)
Leica catalog number: 301-385.160
Legacy Leitz part number: 541065
Production date: 01/98
Connectors: female DB15, male RS232C, female foot-switch connector, mains power inlet, power switch
Power supply: U100-115/230V 50-60Hz, P max 25W
Form factor: external metal enclosure

"Leica DMLD" is an analogue photomicrography system. A standard 35 mm camera is connected to shutter unit 093-050.001-000 (legacy part number 541045). Among its connectors is a male DB15 connector labelled "control panel or power supply". The shutter operates together with the Leica DMLD control panel P/N 301-385.001 (legacy part number 541044).

The entire system is very similar to the earlier MPS52 system (Leitz Leica MPS 52 / Wild Leitz MPS 52).

Based on the following observations:
- the controller offered here is also designated "Leica DMLD"
- part number 301-385.160 belongs to the same numbering group as control panel 301-385.001 (group 301-385.xxx)
- the legacy number 541065 belongs to the same 5410xx numbering group as the shutter controller and the control panel

I believe — although I do not have access to documentation that could confirm this — that this unit is also part of the Leica DMLD analogue photomicrography system, most likely serving as a power supply and shutter control module with provision for connecting a foot switch.
