CompactPWR is an active bus board that combines power generation and distribution, delivering 35W of clean power (1250mA on +12V and -12V rails, 1000mA on +5V) with comprehensive protection features and multiple filtering layers for minimal noise. This space-saving solution (174mm x 79mm) offers flexible power options including a standard 12-24V DC input or optional USB-C connectivity, ensuring your Eurorack modules perform at their absolute best while requiring minimal space in 3U, 6U, and 7U cases.

Description

Konstant Lab is proud to introduce CompactPWR, the ultimate power solution for your compact Eurorack cases. Designed with the same meticulous attention to detail and uncompromising quality you’ve come to expect from us, CompactPWR delivers rock-solid, ultra-clean power in a streamlined, space-saving format. This isn’t just a power supply; it’s an active bus board that combines power generation and distribution, providing a complete power foundation for your 3U, 6U, and 7U systems.

Unleash Your Modules’ Full Potential

CompactPWR boasts a robust 35W of power, with generous current delivery across all rails:

  • +12V: 1250mA
  • -12V: 1250mA
  • +5V: 1000mA

This ensures ample headroom for small cases, allowing them to perform at their absolute best. But power is nothing without purity. CompactPWR is engineered for exceptionally low noise, minimizing any unwanted interference in your audio signal path. We’ve incorporated multiple layers of filtering and regulation to keep your sound pristine:

  • Input Common Mode Filter: Reduces noise from your external power source.
  • Independent DC-DC Converters: Each voltage rail has its own dedicated converter, isolating them from each other.
  • Additional Output Filtering: Further smoothing and refinement of the output voltages.

Precision Engineering, Unwavering Reliability

Beyond clean power, CompactPWR offers features that serious synthesists will appreciate:

  • Active Bus Board Design: A single PCB (174mm x 79mm) integrates both the power supply and a 20-connector (16-pin IDC) distribution board, saving valuable space in your case.
  • Voltage Presence LEDs: Clearly see the status of your +12V, -12V, and +5V rails at a glance.
  • Comprehensive Protection:
    • Overvoltage Protection: Safeguards your valuable modules from potentially damaging voltage spikes.
    • Input Polarity Protection: Prevents damage from accidentally connecting the power brick with reversed polarity.
  • Fine-Tuning Trimmers: Achieve unparalleled voltage accuracy with precision trimmers for the +12V and -12V rails, allowing for adjustments to within 0.02%. This is ideal for calibrating sensitive oscillators and other modules that require precise voltage.

Flexible Power Options

CompactPWR offers a range of power input options to suit your setup:

  • Standard Configuration: Includes an input panel with a 5.5/2.1mm barrel connector and a power switch, accepting 12-24V DC from an external power brick.
  • Optional 40W AC/DC Power Brick: A high-quality Meanwell, Konstant Lab-approved power brick is available in bundle or for purchase separately.
  • Optional USB-C Input Panel: This is where Konstant Lab truly innovates. Replace the standard input panel with our optional USB-C panel. This allows you to power your CompactPWR using a USB-C PD (Power Delivery) charger or power bank capable of delivering 15V-20V and at least 50W. Embrace the convenience and portability of modern power solutions!
  • Global Power Bundle – CompactPWR + USB-C PWR inlet + 67W GaN Charger: Perfect for worldwide use with interchangeable EU/UK/USA plugs. Take your modular setup anywhere with reliable, high-quality power (quality USB-C cable with 2m of lenght included)!
