The EMIX's EMPS-8024 is a switching type 24V DC regulated power supply with two outputs. This public address system has built-in Microchip controller constantly monitors the output voltage and current to ensure that they are within limits when in use. It helps to protect against overvoltages, overcurrents, and short circuits.
When a power failure is detected, the supply voltage will automatically switch to the backup battery (24V). When operating with backup battery, the supply output will be disconnected if the battery voltage falls below 18V, preventing the battery from overheating. The LCD also functions as a voltage and current metre.
