The SMART-PA amplifiers are designed for seamless integration into SMART system solutions and are certified in compliance with the EN 54-16 standard for safety installations.
SMART-PA is a family of transformer-isolated Class D power amplifiers. They allow the utilisation of power from individual channels or in bridge mode, bridging two channels to achieve an output with double the power.
These amplifiers have a 48 VDC input that allows connection to a backup battery system for maximum availability and durability in a voice evacuation system.
The SMART-PA amplifiers are powered by the external power module SMART-PS48800. The current is distributed to individual amplifiers via the "power manager" SMART-PSM48 (the device includes a battery charger and complies with the EN 54-4 standard).
