FS: Ophir head power supply

Up for sale are some power supplies for Ophir heads. These have adjustable regulators so that you can adjust the voltages to suit your Ophir head. This is a good replacement for 9V batteries.



Input: 4.5V-5.5VDC or 6.7V-30VDC (The regulator may require heat sinking at higher voltages)
Output: +/- 5-13VDC
Dimensions: 49mm x 27mm x 14mm

This can be used with a multimeter or voltmeter display to read the laser power from the Ophir head.

Instructions:
1) Hook up to suitable power source.
2) Measure voltages between POS and VGND, set it as desired with R6.
3) Measure voltages between NEG and VGND, set it with R5 to measure the same as the positive voltage.
4) Disconnect power source
5) Hook up the Ophir head.
6) Repeat step 1, 2 & 3.

Price: 30$ CND
Worldwide shipping included.
PayPal fee's included.

Please PM me if you want details or want to buy this.

This is an ESD sensitive device therefore there will be no warranties and no refunds. All sales are final. Each one will be tested with an Ophir head before shipping and wrapped in an ESD bag.

very nice work!!! this looks pretty small, can you tell us the dimensions??

Updates the post. 49mm x 27mm x 14mm

ARG back at it again!

I really don't understand the point for this head.... To avoid using 2 9V batteries? I mean 30 cnd buy a lot of 9V batteries... maybe I am just not seeing it clearly... but someone might elighten me.

This would allow you to build it into one unit and use one set of batteries or on DC plug to power both the Ophir and readout display.

Nobody is forcing you to buy it Go ahead and use 9V batteries if you want, both will work! Also keep in mind out of that 30$ I only keep about ~21$ from sales; the rest go to PP, income tax and shipping.

The advantage I see with this are:
-Using only one battery
-Ability to run off of a wall wart
-Not having to worry about the voltages of the 9V batteries
-Easier to set up than two 9V batteries and a DPST switch
-Ability to zero out your Ophir head correctly with adjustable voltages (Mine zeros out at +/-7v)

Ok I am starting to understand I could also use a lipo battery, or a rechargeable of some kind... Now it's starting to make sense....

Now a question if the battery changes the voltage while its discharging will this thing keep the voltage constant?

Dang norby, you trying to steal the record from infinitus? Haha

Looks great ARG! Definitely better than 9 volts.

If I had an ophir Id buy one

That's the idea

Yup, the output will not change when the battery voltage changes.

How about posting some pics of what you
are selling....

A few Questions...

Is the Output Isolated from the Input ???
Is there an output for driving an LED Display???
Is this Open Source???
Will you post the Schematics if it is???

Ok I am interested in one but I don't have paypal, any other payment method you accept?
