D150SEM and D500SEM class D transformerless amplifiers provide 100, 70 or 50V audio output for distributed loudspeaker systems. The amplifiers are compatible with the V2000SEM amplifier mainframe and LSZDCSEM dual line surveillance interface module. The maximum output power is user configurable from 25W to 150W (D150SEM) and from 25W to 500W (D500SEM). Up to 10 D150SEM or D500SEM amplifiers modules can be housed within a single V2000SEM amplifier mainframe (a mix of both types is possible).
The configurable output power capability of the D500SEM and D150SEM amplifier modules enables very flexible use of the mainframe, with reduced mainframe count, lower quiescent power requirement, and improved environmental performance compared with traditional amplifier designs.
