Description

Details

QHY CFW3

The QHYCFW3 Color Filter Wheel has been improved for compatibility. The original product can only be used to fix 1.25-inch mounted filters, while the updated version can be fixed with 31mm unmounted filters through the new-added screw holes.

Super Thin, Enclosed Motor

QHYCCD selected a high quality ultra-thin hybrid stepper motor for this filter wheel design. Compared to the PM stepper motor used in many filter wheels, the hybrid stepper motor has higher precision, smaller step angle, and is more expensive. The motor is enclosed to prevent dust from entering the motor, thus improving reliability and motor life. The direction of filter rotation can be reversed: The filter carousel can be rotated clockwise or counterclockwise to complete the rotation quickly which is very convenient.

The QHYCFW3 main body is cut from a single piece of aluminum by a precision CNC machine.  The craftsmanship and finish are exquisite.  When you hold the small design, you do not want to put it down!

No Backlash, Precision Positioning

Regarding the evolution of the motor drive, the filter wheels used a gear drive while this 3rd generation filter wheel uses a friction drive that with zero backlash. It also Positions and stoPs with high Precision

Two control modes: 4-Pin QHYCFW Port and USB Port

There is a switch button on the QHYCFW3. The serial port switch can accommodate fast switching between serial communication mode and USB communication mode.

QHYCFW3 support two socket mode. One is the 4PIN QHYCFW socket. If your QHYCCD camera has the 4PIN socket you can connect it directly with QHYCFW3. There is the 12V Power in the 4PIN socket . So it does not need any extra Power supply. 

If you have no QHYCCD camera or the camera has no 4PIN QHYCFW socket. You can use the USB socket to connect with the computer.  Anda  the QHYCFW3 can be powered and controlled with USB Port.  Please note the current requirement when using the USB cable is higher (780mA) than the USB2.0 Port can supply and some computer will limit the current to 500mA. In this condition, QHYCFW3 can draw the power from the QHYCFW socket port (the 6PIN RJ11 Port in the QHYCFW3) and you need a 12V to RJ11 cable to power the QHYCFW2. When using this method. The current drawing from USB cable will reduce to less than 100mA when motor rotating.  (* The 12V to RJ11 cable is in the standard item list after 2019.4).
