Power Supply Block Diagram Description
There are two different types of power supplies in the transmitter, the PA Power Supply
and the Low Voltage Power Supply.
4.5.1
PA Power Supply
There are three power supply configurations available for the Z16HD+ transmitter:
•
3-Phase, 3 wire (197-250 Vac)
•
3-Phase, 4 wire (342-432 Vac)
•
Single Phase (198-250 Vac)
The 3-Phase 3 wire and 4 wire supplies have all of the same components but have a
different wiring harness. The PA power supplies, whether 3-Phase or Single Phase, are
regulated by reliable tap switching techniques which provides excellent efficiency,
while avoiding the power line harmonic problems associated with switching supplies.
The regulation range is 48-54Vdc at 2Vdc per tap.
4.5.1.1
3-Phase Power Supply
The Z16HD+ transmitter uses four main power transformers working in groups of two.
These are designated PS1, PS2, PS3 and PS4. Figure 4-7 shows the placement of each
of the 4 power supplies and connection points for installation or removal of the
supplies.
