Yamaha PW800W Rackmount Power Supply (For Yamaha Digital Mixers)

The PW800W is extremely compact and lightweight (3U, 10kg). Thanks to its high efficiency, the low speed cooling fans are extremely quiet. PW800W can be added as a redundant power supply for CL Series or M7CL. When using with PM5D, two units can be serially connected to achieve failsafe operation. PW800W accepts 100 - 240 volts so it can be used anywhere.
