3.2.1.11 Power Supply Input
The 7705 SAR-Hm and 7705 SAR-Hmc have a single pluggable terminal connector
on the front of the chassis. The terminals are the DC power feed points for a
low-voltage ± 12/24 VDC power source on the 7705 SAR-Hm and a ± 12/24/48 VDC
power source on the 7705 SAR-Hmc. See Preparing the DC Power Connections for
requirements and information about how to prepare DC power cables.
3.2.1.12 High Voltage Power Supply Unit
The Nokia 35W High Voltage Power Supply (HV-PS35) (3HE11298AA) is an optional
and separately orderable component that can be used for high-voltage DC or AC
applications. The HV-PS35 has a small form factor and is designed to be installed
adjacent to the 7705 SAR-Hm or 7705 SAR-Hmc. The HV-PS35 is factory-equipped
with a DIN rail mounting racket. Figure 10 shows the HV-PS35.
Figure 10 35W High Voltage Power Supply
The power input is a pluggable terminal block that supports power feeds of 90 to 264
VAC (50/60 Hz) or 88 to 300 VDC. The HV-PS35 power output is a pluggable
terminal block that delivers a floating 24 VDC.
See HV-PS35 Specifications for technical data and High Voltage Power Supply Unit
