The SMART-PA amplifiers are designed for perfect integration into the SMART system solutions and are certified according to the EN 54-16 standard for security installations.
SMART-PA is a family of class D power amplifiers isolated by transformer. They allow the use of individual channel power or in bridge mode, bridging two channels to obtain double the output power.
These amplifiers are powered through a 48 V DC input. This power is supplied and controlled through the SMART-PSM power supply manager, which connects both to power supplies and batteries. This ensures maximum availability and durability in a voice evacuation system.
