Consideration Description
Power module The power module is an auto-ranging AC-DC converter generating 24V to drive the RVP901
and external fans.
The RVP901 IFDR is delivered with the power supply module attached to the IFDR
mechanical housing.
You can remove the power supply module and mount it nearby in the radar cabinet.
The power supply, fans, and bracket add 8.4 cm (3.3 in) of overall width to the receiver
module.
Power modules are available for 100 ... 240 VAC at 47 ... 63 Hz or 18 ... 36 VDC. The AC
power supply is a low noise, low ripple, auto-switching unit. The DC input voltage may be
unregulated.
If DC voltage is selected as an option, 3 fan assemblies are available. These fan options allow
DC voltages from 12 ... 18 VDC and 18 ... 28 VDC.
The IFDR has an internal regulator to supply the digital circuits the voltages need. The
internal regulated power modules are sized to provide several Watts more than is required
by RVP901. A ferrite choke around the supply wires, near the terminal strip, is also
recommended.
For information on the power harness needed to supply power to the RVP901 and fans, see
9.4 RVP901 IFDR Specifications (page 331) and B. RVP901 IFDR Technical Drawings
(page 369).
