UcD250LP OEM
Product information "UcD250LP OEM"
The UcD250LP OEM amplifier module is designed to support a wide range of professional audio applications where higher output power is required within a compact form factor.
The low profile mechanical design allows integration in space constrained systems and makes the module suitable for multichannel configurations. The module provides increased output power compared with lower power variants, while maintaining efficient Class D operation and predictable performance characteristics.
The UcD250LP OEM amplifier module is intended for use in public address systems, studio equipment and controlled home audio applications. Its design supports reliable operation under typical operating conditions encountered in professional audio installations.
Crafted to be compact
One of the hallmarks of the LP family of modules is the carefully-crafted and compact design. This is not merely an aesthetic consideration – it fulfills a very real need for space-limited applications. The combination of its low-profile design and great audio capabilities positions the UcD™ family as the epitome of sophistication in amplifier technology.
With the growing demand for audio solutions that serve space-limited environments, the UcD™ family is the perfect choice for multichannel applications where a compact footprint and uncompromised audio quality are paramount.

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.
