Hello, it is in Yinzhou Investment Industry Park.
Unfortunately I have canceled my Ningbo visit due to time constraints (I have to attend the Pro Light & Sound show in Shanghai instead). I then have to travel to Shenzen/Gaungzhou and Singapore.
Next trip will be Ningbo. I'll contact you then, thanks for the offer!
This space for rent.
we should move this conversation to laserchat.

Looking at the the above it seems this driver will power two LDs simultaneously !!
It seems to have + or (high side) and return as well as - or (low side) and return.
Which begs the question of what happens when an isolated LD (eg.445nm or 637mitsu)
is connected from + to - ignoring returns, or are these outputs mutually exclusive?
Also the Rt (thermal feedback) values don't seem to match Dimitri's comments.
Quote hobbybob : from what i understand, the white 5W resistor on the heatsink of .33 Ohm needs to be changed to 0.1 Ohm
I assume this has a lot to do with the thermistor/peltier being used which doesn't appear to be on offer by Laserever .............. your cue David
The 5V open frame switching-mode power supply can be tuned up. = how? where?
More photos/signal specs please the open frame (LSR-PS-NI) no frills version looks very interesting (no price ?) but web page lacks all the above details (also heat sink attachment details). ... the devil is definitely in the detail.
IMHO if these and other details were to be supplied then a GB might well have some success.
Also I am very interested in the reply to the doc!
drlava quote: "Hello David, this sounds very similar to the aixiz lens, but a better price. Does it have the same optical properties and somewhat lossy 0.3 numerical aperture?"
Cheers
dEAR Catalanjo,
We used my driver LSR-PS-1 of my 150mW green lasever for testing.
Edison has contacted Dave and from him came the information to change the big 5W resistor from 0.33Ohm to 0.1Ohm to use it for Blue 445 diodes. Edison has already bought 20 drivers from Lasever.
When i look at my old driver it has R33 on it 0.33Ohm and i bought 2 drivers from Johan.
These drivers have R1 on them. 0.1 Ohm.
I had already had these drivers working on the UKLEM, with Peltier supplied by Lasever, With Thermistor supplied by lasever. Works like a charm.
So i don΄t understand your comments. I just thought to share my info
And i don't understand what the size of this resistor has to do with the thermistor size ?
If Dave from lasever says it needs to be changed, and the voltage needs to be upped to 5.5V why should we doubt it ? It works, i proved it during UKLEM, i am probably missing something ? Sorry if i misunderstand you.
I didn't fail !
I just found out 10,000 ways that didn't work.
