# Description and specifications:
Carl Zeiss power supply for microscopes using illuminators with 6 V lamps (typically halogen lamps) rated at no more than 20 W.

Basic specifications of the power 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.

# Examples of use
- if you're missing a power supply
- if your power supply is damaged
- if you're using two illuminators and need a second power supply
