ZN3018-7 2RU EXTERNALPOWER SUPPLY UNIT
A Calrec designed special unit to provide + 16 volts audio power, 8 volts logic
power (stabilised in modules at 5 volts where required), and 48 volts phantom
power suitable for approximately 16 channels each in a typical console. It is
recommended that there be a second external power supply in the system to
act as a “Hot” spare which in addition will share the load.
The 2U units include a monitor of the 4 outputs and send a fault signal to the
console in the event of a failure. The units operate in parallel via internal
diodes and are designed to operate at mains voltages 10% below that set.
Please note : The small frame M3 is supplied with an internal Power
Supply Unit. Should an external Power Supply Unit be used
as a “hot” spare for this, then load-sharing will not occur.
