Hypex SMPS400A100 2 x 37 VDC 400 Watt Switch Mode Power Supply
The SMPS400A100 stands out in the power supplies market thanks to its thorough optimization for audio applications, especially in combination with the UcD amplifier modules. It offers dual symmetric 37 VDC outputs and advanced over-current protection, which intelligently reduces output voltage during short overloads and only fully shuts down when necessary. With a weight of just 300 grams and the ability to fit in a 1U rack enclosure, it is ideal for space-constrained or portable audio equipment.
Perfect for both DIY and professional builds, this model is designed to supply single or multiple UcD range amplifier modules. Its advanced protection features, including remote-controlled standby and automatic amplifier enable, provide peace of mind for critical audio installations. The included Hypex Cable Set SMPS400 ensures effortless and secure connections, making assembly straightforward and reliable for users of all skill levels.
Thermal management is a key consideration in the SMPS400A100’s design. With an efficiency of up to 92 percent and low idle losses, it generates minimal heat compared to traditional linear power supplies. However, adequate cooling is still recommended to maintain performance, especially in high-power or continuous-duty setups. The supply features built-in thermal shutdown as a safeguard, underscoring its reliability even in demanding environments.
This power supply is not only suitable for amplifiers and speakers in active systems but is also an excellent choice for amplifier modules and active home audio projects where clean, dynamic power is essential. Its low electromagnetic interference profile and support for remote control make it a favorite among audio professionals and hobbyists seeking uncompromised performance and integration flexibility.
