This is description of this part:
Power supply for the HBO 200 fluorescence illuminator used in Zeiss Universal, Zeiss Photomicroscope and other microscopes.
Basic specifications of this power 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.
What is this part needed for?
- if you have a compatible Zeiss microscope illuminator but are missing the power supply
- if you already have this power supply but it is damaged
