FOR SALE: 3A SELECTABLE TEST LOADS​


UPDATE: ***TEST LOADS ARE IN STOCK AS OF 1/26/15***

These test loads have jumper terminals to select the number or diodes, 1-10, you want to use or simulate a specific voltage drop.

Now, for some people who are wondering what is a test load/dummy load and why do we need it? A test load or dummy load acts like or simulates a laser diode to safely measure how much current is going through it from the driver. Without one you run the risk of destroying or damaging the laser diode.

NOTE #1: These diodes are safely rated up to 3A, but at higher currents (more than 1A) they will get hot. I would advise less than 1 minute cycles for high currents or if you want you could place a small heat sink on top of these diodes and or resistor to help cool the test load if you plan on using these for more than 1 minute. Easy to find small heat sinks at RadioShack, DX, or you can source your own.

NOTE #2: If the driver you are using has a capacitor (most likely), you need to discharge the capacitor using a resistor before connecting it to the actual laser diode to prevent voltage spikes that might kill it or damage it.

They compose of:
- (1) Custom test load PCB
- (10) 1N5404 diodes (rated up to 3A)
- (18) male straight gold plated breakaway headers (rated up to 3A)
- (1) jumper connector
- (1) metal oxide 1 Ohm 5 Watt 2% tolerance resistor

10 diodes for a selectable range (number designates diodes on the jumper)
*remove jumper pin to use all 10 diodes*

Size comparison to a quarter:
*All assembled test loads are tested to ensure they work properly*


DIY kit:


There are 2 options:
Option 1: A fully assembled test load
Option 2: DIY kit. I'll provide all components and you can solder them on.

Pricing:
- PayPal only
- If you require signature confirmation it will be an extra $2.10

Option 1: $14 + shipping + PayPal fees
Option 2: $10.50 + shipping + PayPal fees

Shipping:
Domestic: USPS First Class Mail w/ tracking #
International: PM me first

PM me or post here if your interested.

:thanks:

Re: FS: Selectable test load up to 3A

Are the holes pre-drilled, or do we need to drill them ?

Yes, the holes are already drilled. Sorry, I know the pictures aren't the best quality.

Oh and rhd the new driver PCBs came in today! Just PM me your shipping address (I lost it) so I can send you a set. :)

Re: FS: Selectable test load up to 3A

does the defective one comes with the components too or is it just the board?

Re: FS: Selectable test load up to 3A

It's just the board. I don't have enough components to cover the defective ones, but I could include the headers. I'm pretty sure I have extras for those.
