Break on through to the other side
ICEpower’s amplifier power modules enables audio manufacturers to bring innovative, high-quality products to the market fast and cost-effectively. Combining great sounding class D amplifiers with switch mode power supplies results in compact and efficient solutions. Available from 50 W to 1200 W and from 1 to 16 amplifier channels, ICEpower’s amplifier power modules are available for many types of applications.
Faster to market
Using an ICEpower amplifier power module frees up your development resources, enabling you to focus on developing product features that truly differentiate your product. To deliver on this promise, ICEpower amplifier power modules are pre-approved for Safety, EMC and RoHS compliance with all certificates available through ICEpower.
No upfront investment
The fact that no upfront investments are required for product development means that using an ICEpower standard module secures cost competitiveness even at low manufacturing volumes. All ICEpower’s amplifier power modules are based on Class D amplification techniques resulting in extra ordinary audio performance with high efficiency.
Quality and reliability guaranteed
We have been able to consistently achieve a less than 0.2% field return rate over the last 10 years. This has been possible through careful design with conservative component de-rating, use of high quality brand name components, and meticulous end of line production testing and burn-in.
