Hypex SMPS3kA400 2 x 65 VDC 3000 Watt Switch Mode Power Supply

The Hypex SMPS3kA400 is a high-performance switch mode power supply engineered to deliver exceptionally clean and stable power for demanding audio applications. As part of Hypex’s renowned range, this module sets a benchmark for efficiency and reliability in professional and DIY amplifier builds.

This power supply is ideally suited for powering high-current class-D amplifiers, active loudspeaker systems, and multi-channel installations where consistent voltage regulation is critical. Whether you are constructing a studio monitor system, a high-fidelity home theatre amplifier, or a commercial sound reinforcement setup, the SMPS3kA400 provides the robust foundation required for transparent, dynamic audio reproduction.

Technically, the module delivers up to 3000 watts of regulated power across two independent 65 VDC outputs, each rated at 23 amperes. This dual-rail configuration allows for flexible bi-amplification or separate supply to left and right channels, minimising crosstalk and enhancing stereo imaging. Advanced switching topology ensures high efficiency with low electromagnetic interference, while comprehensive protection circuits guard against overcurrent, overtemperature, and short circuits. The compact, low-profile design facilitates integration into chassis with limited space, and the included standby and remote control functions add convenience for system integration.

For builders and engineers seeking a premium, high-current power solution, the Hypex SMPS3kA400 offers uncompromising performance and long-term reliability.
