What are SMPS used for?
A Switched-Mode Power Supply (SMPS) is the beating heart of modern high-performance audio. Traditional linear power supplies rely on heavy, bulky transformers and large capacitors to regulate voltage, which inherently wastes energy as heat and can introduce low-frequency mains hum (50Hz/60Hz) into the audio path. Hypex SMPS technology changes the game. By operating at high frequencies, our SMPS modules deliver exceptionally clean, regulated power with maximum efficiency. This drastically reduces the physical size and weight of the unit, eliminates audible hum, and provides lightning-fast transient response. For compact, efficient, and ultra-low-noise audio systems.

FAQ's about Hypex SMPS
Are Hypex SMPS modules safe for home use?
Absolutely. Hypex SMPS modules are designed as Safety Class 2 devices and comply with applicable safety and performance standards for professional audio equipment. They include built-in protection mechanisms such as advanced overcurrent protection, overtemperature protection, and fault-triggered shutdown (latched-off behavior), ensuring reliable and safe operation when properly integrated.
Can I use Hypex SMPS with other amplifier brands?
Yes, you can. While Hypex SMPS modules are specifically designed for use with UcD, NCORE® and NCOREx® amplifier modules, they are general-purpose high-efficiency power supplies for audio applications. They provide regulated output voltages, auxiliary supplies, and control interfaces intended for amplifier integration. As long as the electrical requirements of your amplifier (voltage, current, and interfacing) match the SMPS specifications, integration is possible. Practical implementation may require adapting wiring and control connections.
How does a SMPS convert AC to DC?
An SMPS handles power conversion in a highly efficient, multi-step process:
1. Rectification: Incoming AC mains power (e.g. 110 V / 230 V) is converted into DC.
2. High-Frequency Switching: This DC is switched at high frequency (typical switching frequencies around 100 kHz are used in Hypex SMPS designs).
3. Transformation & Isolation: The high-frequency signal is processed through a transformer, enabling voltage conversion and isolation.
4. Final Rectification & Regulation: The output is converted back to DC and regulated to provide stable supply rails. Because the conversion takes place at high frequency, the transformer can be significantly smaller compared to linear designs, while still maintaining stable output voltages across load conditions.
When should a SMPS be used?
A SMPS is preferred in any modern audio application where performance, space, and thermal management matter. It is the ideal choice for high-end HiFi, professional studio monitoring, and pro-audio touring rigs where high efficiency, low weight, and stable output voltages are critical. If you want a noise-free, massive power delivery without the physical footprint and heat of a traditional heavy transformer, an SMPS is the superior solution.
What makes a Hypex SMPS different from standard power supplies?
Standard off-the-shelf industrial SMPS units are built for generic machinery or IT hardware, meaning they lack optimization for dynamic audio behaviors. Hypex SMPS modules are designed specifically for high-end audio. They are capable of delivering immense peak power on demand to handle musical transients seamlessly, feature exceptionally low electromagnetic interference (EMI), and provide highly regulated auxiliary voltage rails tailored specifically to power low-noise amplifier input stages.
Are Hypex SMPS modules suitable for beginners?
Yes, thanks to our DIY-friendly architecture. While handling mains voltage always requires respect and caution, Hypex minimizes the complexity. Our modules are designed with plug-and-play internal connectivity. By using our pre-terminated cable sets, beginners can safely build high-end gear without needing an engineering degree or advanced point-to-point soldering skills.
What safety features are included in Hypex SMPS units?
Hypex SMPS modules include several built-in protection and safety mechanisms, such as: Advanced overcurrent protection (current limiting and hiccup mode under persistent overload). Overtemperature protection. Fault-triggered shutdown (latched-off behavior via control circuitry). DC detection input (depending on model). They are designed as Safety Class 2 devices and must be properly installed due to the presence of hazardous voltages.
Can a Hypex SMPS be used for both mono and stereo amplifiers?
Absolutely. Our range effortlessly spans both design paths. For instance, you can use a single SMPS400 or SMPS1200 to drive a pair of amplifier modules in a stereo layout. Alternatively, for the ultimate channel isolation and crosstalk reduction, audiophiles frequently use one dedicated SMPS per amplifier module to build high-performance monoblocks.
