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 bridge mode, bridging two channels to achieve 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.| FEATURES: | Class D power amplifier. Isolated output with transformer. The output channels can be used in bridge mode. 100 V or 50 V speaker line output. Front panel indicators for Power, Active and Fault. The SMART-PA series is combined with the SMART-PSM48/E Power Manager (charger and back-up power supply). |
