Product information "UcD400 OEM"

The UcD400 OEM amplifier module is a Class D amplifier module designed for efficient audio amplification in a wide range of applications.

Compared with the low profile version, this OEM module includes additional detection and protection functions. These include clipping detection and DC fault protection, which are intended to reduce the risk of damage under abnormal operating conditions and support stable long term operation.

The module incorporates an integrated buffer stage to support proper signal interfacing and stable operation within larger system designs. This contributes to controlled signal handling and predictable behaviour.

The UcD400 OEM amplifier module is suitable for integration in professional audio equipment, studio installations, home audio systems and other audio amplification applications where higher output power and reliable operation are required.

Hypex SMPS400Axx0 Switch Mode Power Supply

SMPS400A400

The SMPS400 is a high efficiency Safety Class 2 switch mode power supply designed for use with UcD™ amplifier modules. The unit is intended for audio applications that require compact dimensions, low weight and stable power delivery over a wide load range. The power supply includes an overcurrent protection mechanism that reduces the output voltage during temporary overload conditions. If the overload condition persists, the supply enters hiccup mode and remains in this state until the overload is removed. This behaviour, combined with the use of large electrolytic buffer capacitors, supports short term peak power delivery to the connected amplifier module. The SMPS400 includes an auxiliary isolated supply and a control interface intended to operate with UcD amplifier modules. Built in actuators allow the power supply to be enabled during normal operation or disconnected in the event of a fault condition. The design of the SMPS400 focuses on low levels of radiated and conducted electromagnetic interference. The topology and layout are optimised to meet EMI requirements commonly associated with professional audio applications. The SMPS400 supports a selectable input voltage range, allowing operation with different mains supply specifications. This makes the unit suitable for use in international applications with varying power grid standards. Being a 2-quadrant full bridge rectifier, SMPS400 is able to supply single ended class d amplifiers. The SMPS400 complies with applicable safety and performance standards and is certified for use in professional audio equipment. HIGHLIGHTS • High efficiency • Small form factor • Low EMI • Designed to fit in a 1HE rack space FEATURES • 2-quadrant full bridge rectifier • Selectable input voltage range • External controlled operation • 3 variants available: A100 / A180 / A400 PROTECTIONS • Advanced Overcurrent protection • Over temperature protection • DC detection input POSSIBLE APPLICATIONS • Active Loudspeakers, for home and professional use • Power Amplifiers, for home and professional use • Line Array and Immersive Systems • Home Theatre Systems • Multichannel Power Amplifiers Notes: The SMPS400A100 is not available for DIY customers.
