Section 1 Introduction/Specifications
Platinum Z16HD+
Display, permits extensive viewing of internal voltages, temperatures and a detailed
Fault Log to easily pin-point problems. Long-life LED fault and status indicators and
reliable membrane switches provide local control and selection for the transmitter.
1.3.5
Directional RF Sample Port
Platinum ZHD+ transmitters provide an RF sample port with 30dB or greater directivity
(Typically 40dB). A directional RF sample provides more accurate performance
measurements by supplying a nearly reflection free RF sample source for external
monitoring equipment.
1.3.6
Power Supplies
The Z16HD+ can be configured with a 3-Phase or Single Phase power supply. Both of
these supplies are Quad units, with each supply powering 1/4 of the PA amplifiers. Most
other sections such as the IPA and the control system are powered from at least two of
the four supplies. The supplies are regulated by reliable tap-switching techniques (non-
switching design). This approach provides high conversion efficiency and excellent
power factor with very low line harmonics, in an easy to service design. The power
supplies are mounted on a roll-out mounting plate for complete accessibility. The
multiple-supply concept protects against total loss of service due to loss of a single
supply.
NOTE:
For the Z16HD+ Single Phase version, a second cabinet is required to house 1/2
of the larger power supply. The upper half of the second cabinet is then available
for other standard 19" rack mount equipment.
1.3.7
Air System
The Platinum Z uses a 2 speed fan to pull air in the back of the transmitter and exhausts
it out the top. There are air channels up through the PA assembly for cooling. Upon
startup, the transmitter will run at high speed for 1 minute, the will drop to a lower
speed provided there are no active faults. If a fault does occur during normal operation
the fan will automatically switch to high speed. For detailed airflow information, refer
to the Cabinet Outline Drawing in the schematic package.
