the Blackmagic Design Spares - Fiber Converter - Studio PCB PSU is the internal power supply unit for the Blackmagic Studio Fiber Converter (the 1RU rack-mounted unit). This board is the "heavy lifter" of the fiber ecosystem, responsible for converting standard AC mains power into the high-voltage DC required to power a camera over up to 2 km of SMPTE hybrid fiber cable.

The Powerhouse of the SMPTE System

Unlike a standard camera power supply, this PSU is highly specialized for the SMPTE 311M standard.

  • High-Voltage Transmission: It generates the high-voltage DC (typically around 200V-240V) required to overcome the electrical resistance of long fiber runs, ensuring the camera receives a stable 12V-14V at the other end.

  • Safety Interlock Logic: The board contains "Sense" circuitry that monitors the fiber connection. If the cable is unplugged or damaged, the PSU instantly kills the high-voltage output to prevent accidental electrocution.

  • Multi-Rail Regulation: In addition to the camera power, it provides low-voltage rails (5V, 12V) to power the converter’s internal processors, the 12G-SDI video paths, and the front-panel LCD.

When to Replace the Studio PSU

Since the Studio Fiber Converter is often powered on 24/7 in a server room or OB van, the PSU is subject to significant thermal stress.

  • Total Power Failure: The unit fails to turn on, and the front panel remain dark despite a verified AC power source and fuse.

  • "Camera Power" Errors: The Studio Converter powers on and shows video, but fails to send power to the camera (the "Power" light on the front panel remains red or unlit).

  • Audible Whining/Buzzing: High-pitched coil whine or buzzing often indicates that the capacitors or transformers on the PSU are reaching the end of their life cycle.

  • Intermittent Restarts: If the fiber link drops specifically when the camera's power draw increases (e.g., when turning on phantom power or a high-brightness monitor), the PSU may be failing under load.

Key Features

  • Genuine OEM Part: Specifically tuned for the current draw and safety requirements of the Blackmagic Fiber ecosystem.

  • Industrial Grade: Designed for high-reliability environments where "downtime" is not an option.

  • Integrated Protection: Features over-current, over-voltage, and short-circuit protection to prevent a faulty fiber cable from destroying the rest of the converter.


Technical Installation Note

DANGER: High Voltage. Replacing this board involves working with mains electricity and high-voltage DC storage.

  • Capacitor Discharge: Even after the unit is unplugged, the large capacitors on this board can hold a lethal charge for several minutes. Wait at least 10 minutes after unplugging before touching the board, or use a voltmeter to verify it is discharged.

  • Thermal Bonding: Ensure that any thermal pads or standoffs are reinstalled exactly as they were. This PSU relies on the metal chassis of the Studio Converter to act as a heat sink.

  • Interlock Continuity: When reconnecting the wiring looms, ensure the "Sense" lines are securely seated. If the interlock wire is loose, the PSU will refuse to send high voltage to the camera as a safety precaution.

  • Grounding: The ground wire must be securely bonded to the chassis. A floating ground in a SMPTE fiber system can lead to massive "static pops" in the audio or 12G-SDI signal interference.

Expert Advice: Before replacing this board, always check the external SMPTE cable and the internal fuse (usually located near the AC inlet). Many "PSU failures" are actually just a tripped safety fuse caused by a temporary power surge in the studio.

Is your converter failing to power on at all, or is it just failing to send power down the fiber line to the camera?

Defective toy and inconsistent quality.
Size: X-Large, Color: Raccoon, Size: X-Large, Color: Raccoon
My initial review was 5 stars based on my experience with a previous order (blue raccoon) and the fact my puppy was immediately interested in it. However, I did not give it to her to play with until this past Friday (May 21, 2026) because she had the first one I bought. In a matter of 2 days the seam on the back and at the base of the head unraveled and all of the stuffing was scattered all over the room. I thought I’d found some good, high quality, toys for her but apparently this one was defective because the first one had had a lot of use and I’d still in decent shape. This is too much money to pay for a dog toy that only lasts a day or two so be advised they aren’t all good.

Bigger, louder, crinklier, softer, than expected!
Size: X-Large, Color: Rabbit
My dog was gifted a collection of used toys and he really likes a very long stuffed pig which, unfortunately, another dog that is a destructive chewer, totally destroyed. I decided to break down and buy him another long stuffed toy today and since he's always blissfully watching rabbits in the yard and neighborhood I chose the rabbit version. This thing is huge which is great for him- he's 62 lbs and 7 months old and only half grown. He loves it, it has multiple LOUD squeakers, lots of crinkly spots, and fun ears/legs to grab hold off. He's a big fan and it's made with K9 Tuff Guard which LASTS. Super soft and easy to wash. Update after 2 months- easy to wash and looks new after a washing. very durable so far, standing up to indoor and outdoor use. He is not a destructive chewer but whips them around, tramples on them, steps on them while running top speed and chomps on the annoying squeaker for hours. one squeaker has a hole and its tune is now slightly muted (thank god)

So many squeakers!
Color: Squeaker Matz Gator, Size: X Large (Pack of 1)
I have 3 golden retrievers. They love this toy. While the head came off because they played tug-o-war with it, the rest has held up mostly for 5-6 months. At this point sometimes a squeaker will pop out. There are so many squeakers in this toy! However, they still use it for tug-o-war, I am surprised it has lasted this long. There is only stuffing in the head.

Cute, durable toy.
Color: Squeaker Matz Gator, Size: X Large (Pack of 1)
It's about as durable as you can expect a stuffed animal to be. I have two new puppies who are still teething and they love these things. I got the Kyjen sheep mat version (it's a square shape, rather than the two rows of squeakers) for the little girl. Both dogs sleep with it in their crate and we take them on trips with us. I've gone so far as to open up the toy and replace the broken squeakers (costs about 5$ for 30 large squeakers). The rest of the toy is fine. Our german shepherd puppy absolutely loves the rattle that's located in the head of the gator as well. The rattle also helps initially getting the dog engaged with chewing on the toy rather than your clothing or furniture. Then they discover the squeakers and it's endless entertainment and a good distraction for your dogs. I haven't had any problems with the thin, decorative material that's represent the teeth, claws and back fins. It's a slightly thicker felt that's soft and flimsy. Honestly, I'm not worried about it. Even if they were to eventually chew these off, they're not a choking hazard. Our little guy has thrown up solid pieces of kibble that are larger and harder than this. Seriously now, common. The eyes are sewn into the head, so there's no risk of pulling them off and swallowing. I toss these in the washer on a gentle cycle to clean off the slobber and dirt about once every couple weeks and the squeakers are fine, though they sometimes have to dry out to be 100% functional again. It never takes long. Overall, I love the amount of squeakers just due to the breaking problem with have with single squeaker toys. Once they break, the dog loses interest. Which is also a nice way to train the dogs the difference between the non-squeaking kids toys. The dogs absolutely love this toy and wont sleep without it. When the fabric eventually wears out (not even a slight issue after a few months), I'll be buying another one.

Great Toy, HUGE, small dog loves,
Color: Squeaker Matz Gator, Size: X Large (Pack of 1)
For the price this is my favorite toy! My 4 lb Chihuahua LOVES this thing. He is smaller than it by a long shot, yet he loves to parade this around, showing how big he is and can handle this huge GATOR. LOL. Friends come up to the porch, and he runs back to grab his GATOR to bring it up for them to see. Only thing with these toys - for my dog - we have several of these he loves - he cannot make them squeak. He jumps on them, chews on them, but just doesn't have the power. That being said, think about it, he loves the things, I mean LOVES. Sleeps with them, parades them out, fights with them when he's alone, has a great time - .... Evidently, it's me - I MISS THE SQUEAK! I watch him, and root for him, and every now and then (rare), I hear he got a squeak. Still, he doesn't care! So.... interactive time! I go out and play with him and Mr. GATOR, and I make it squeak, and we all have EXTRA fun. Note, my little guy is what they call an EXTREMELY AGGRESSIVE CHEWER. He chews in his sleep (kidding). He's really a tough chewer. He however, uses these more for wrestling, and attacking, and carrying around and sleeping on, etc. So none of ours have tears in them, though he does attack and chew all of it - I think these products are super wonderful, and I have to buy several more, like the hide-a-toy ones (beehive, squirrel, etc.) because I know the quality, I know my Chihuahua loves them to pieces - while he hasn't actually been able to render them in pieces! Win-win for us. You decide what your dog is like. Mine has his snoopy blanket and a huge victory in his mind over this large GATOR - his friend all day long.
