The Blackmagic Design Spares - Power Module - 12VDC 225W is a heavy-duty internal power supply unit designed for the most power-intensive hardware in the Blackmagic lineup. Providing a massive 225 watts on a 12V DC rail, this module is engineered for "Enterprise" class devices that feature high-density FPGA processing, extensive 12G-SDI crosspoints, or large arrays of physical controls.

High-Current Performance

With a 225W rating, this module can deliver approximately 18.75 Amps of current. This high capacity is necessary for devices that manage significant heat dissipation and complex mechanical tasks simultaneously.

  • Voltage: 12V DC (Standardized for high-end broadcast logic).

  • Wattage: 225W (High-overhead for mission-critical reliability).

  • Input: Universal AC 100V–240V.

  • Efficiency: Designed for 24/7 "always-on" environments like broadcast master control rooms and live production trucks.

Compatible Hardware

This power module is typically found in Blackmagic's "flagship" 2RU and larger devices, where a 60W or 150W supply simply wouldn't provide enough current:

  • ATEM 4 M/E Broadcast Studio 4K: The massive processing requirements for 80+ inputs and multiple M/E rows require this level of power.

  • Smart Videohub 40x40 (12G-SDI models): Routing forty 12G-SDI signals creates significant thermal and electrical load that requires a high-amperage supply.

  • Teranex AV / Express: Standards converters that perform intense real-time pixel processing and frame rate conversion.

  • Universal Videohub Frames: Used in modular router frames to power multiple I/O cards.

Symptoms of Failure

Because this module handles such high current, failures can be more dramatic than in smaller units.

  • Thermal Shutdown: If the module's internal cooling or capacitors degrade, the unit may shut down under load (e.g., when all 40 SDI ports are active).

  • High-Frequency Whine: A common sign of aging capacitors in a 225W supply, indicating it can no longer provide "clean" DC power.

  • Fan Failure Triggers: In some units, if the power module's voltage rail dips, the system fans may spin at 100% (failsafe mode) or stop entirely, leading to a secondary overheat on the Main PCB.

Key Features

  • Broadcast Grade: Low-ripple DC output to ensure no electrical noise is introduced into the SDI video signals.

  • Active/Passive Hybrid Cooling: Often features its own integrated heat sinks and is positioned near the unit's main fans for maximum longevity.

  • Redundant-Ready: In many 225W devices, these modules are designed to be paired with a second module for power redundancy.


Technical Installation Note

Replacing a 225W power module is a high-level repair that requires strict adherence to safety protocols.

  • Lethal Charge Warning: The large primary capacitors in a 225W supply can store a lethal electrical charge for a significant amount of time. Wait at least 15 minutes after unplugging the AC source before opening the unit.

  • Terminal Integrity: Unlike smaller modules with plastic clips, 225W units often use screw terminals or high-density spade connectors for the 12V output. Ensure these are tightened to the correct torque; a loose connection at 18 Amps can cause electrical arcing and fire.

  • Mounting and EMI: Ensure all mounting screws are used. This module generates a significant electromagnetic field; the metal chassis serves as both a heat sink and an EMI shield.

  • Airflow Check: When replacing the module, inspect the internal chassis fans. A power module failure is often preceded by a fan failure that caused the supply to bake in its own heat.

Are you replacing this in a Videohub 40x40 or an ATEM switcher? Knowing the specific device can help determine if there are additional calibration steps required.

Sense and Practicality Found Here
This book is a great way for couples to discuss matters that are really important. It is a great way to talk about the things that are all too often "unspoken" even with the greatest of couples. This book gave us a way to make sense of our thoughts, in an easy non-judgmental and open way. It wasn't that we hadn't voiced these ideas or matters, just that we hadn't thought about the matters fully. That is what this book is for: discussing. One of the greatest parts of the book is discussing your family's unspoken rules. My fiance and I had already discussed several of the matters in the book (and thought we had done so successfully), just not as thoroughly as the book asked of us. This really helped us understand each other and our perspectives. Some of the matters in the book seem to be on the naive side, maybe assuming a more modest and conservative lifestyle of its readership (perhaps written especially for couples that haven't gotten to spend a lot of time around each other for extended periods), but there is enough reality to keep topics and discussion flowing. It is an easy fast paced read. This book presents a comfortable and laid back way of discussing the things you may have already thought of but never got the time to bring full circle.

Practical and helpful
Format: Hardcover
This is a great book. My husband and I gave one copy to one of our sons as he started to have relationship troubles; this book helped him immensely in getting to the core of what makes a relationship work. We gave a copy to our other son when he got engaged, and we don't know if he simply read it and responded to the questions or if he used it as a springboard to start conversations with his fiancee. All I see is that they have become more of a team, better at communicating, and very happy as they focus on their future marriage. Note that I said "marriage" and not "wedding" - the more important focus! My husband and I are Christians; the perspective of a Christian couple is clear in this book, but in addition to that, the Parrotts bring professional training and clear writing to the table. Their questions and discussions are insightful and sometimes humorous, making it an easy-to-read book. This is a practical "handbook" for couples at all stages of serious relationships, from pre-engagement through married for many years.

Great for Premarital Counseling
Format: Kindle
My wife and I use this book and the SYMBIS assessment in premarital counseling. It is very helpful, and the couples have loved it.

A Must Read For Adults prior to Marraige!
Format: Hardcover
I was a a wedding this past Spring and the minister was so inspiring and even with 37 yrs of marriage I learned something so I asked him what he did with the young couple for pre-marriage counseling and he referred this book! I read it and it is spot on. You don’t need to be a Christian to benefit from it. I purchased 2 more for each of my children who are in their late twenties and dating. It makes you think about the realities of what you really want in a relationship and to focus on what is important. Highly recommend!
