Details
Sure Electronics OEM Constant Voltage Audio Amplifier Module & Power Supply for Public Address & Fire Alarm System
Overview:
Constant voltage communication is common used in applications where miles of cable are used for transmission, they minimize resistive power loss by running the power as high voltage and low current. Sure Electronics provides complete audio amplifier and power supply solution - CVA Series (without step-up transformer) from 100W - 500W, which can be applied to audio communications in the form of a constant-voltage system (typically 70-200 volts). Such a system is often used when a single power amplifier drives many loudspeakers through long cable runs (over 50 feet). Some examples of this condition are distributed speaker systems for P.A., Broadcast, paging, or low-SPL background music.
Note: This is a virtual link and the price is for reference only. We have more than 4 designs for PA System, from traditional constant voltage solution with step-up transformer to transformless audio solutions. Please contact us at info@sure-electronics.com for any inquiries.
