2.0 Overview
2.1 General Description
Your NEWMAR Site Power Monitor, model SPM-200, web-enables and integrates intelligence to any site’s AC
and DC power system for 24/7 monitoring, alarm condition notification, and data logging of vital electrical
functions. All sensor inputs are programmable, accessible, and managed via the Internet: TCP/IP or SNMP.
View current conditions and log 30 day history of DC and AC power status at remote sites before dispatching
personnel.
The SPM-200 is designed specifically for monitoring power supplies, rectifiers, batteries, converters, inverters,
UPS, power distribution panels, and AC power at communication sites, base stations, outdoor enclosures and
command vehicles via Ethernet or Wireless connection. The unit can be rack, DIN-rail, or wall mounted and is
easily adapted to virtually any make of power system via nine sensor input ports which capture and stream
critical data via the internet for analysis and logging of site history. Web page based programs are easily
user configured for site parameters with up to 50 desired alarm conditions settings and multiple automatic
notification options by e-mail, PDA, and mobile phone via text messaging.
Sites without internet access can use the monitor solely as a data logging instrument that captures and retains
a 30 day history file, ready for download to a spread sheet on a lap top computer during maintenance visits
for recording site history and analysis of component performance and failure conditions.
2.15 Front Panel LED Indicators
Status:
Flashes on when polling sensor inputs. Approximated once every 5 seconds.
Power:
Illuminates when DC input power is present
2.2 Sensor Inputs
In addition to a built-in temperature sensor, the SPM offers the following 9 sensor ports:
2.2.1
Voltage
DC: 3 Ports:
• 2 each 0 to +40 VDC (Negative Ground), typ6, +12, +24V systems
• 1 each 30-60 VDC (Positive Ground), typically -48V systems
CAUTION:
If you intend to power -48 VDC
AND
monitor -48 VDC, input power
must
come from an isolated
DC converter. If you need one, we will provide it free of charge. Contact NEWMAR: 800-854-3906 or E-Mail:

Accuracy
±
3%
AC: 2 Ports:
• 90-264 VAC utility power (L-N Single Phase) Floating
• 90-135 VAC inverter output, Single Phase
Note:
This input can be used to monitor a second utility or generator source providing it’s a Line to
Neutral source with grounded Neutral which must be connected to “INV IN (GND)” Terminal # 4
WARNING!
Inverter GND terminal 4 is common to all SPM grounds and returns.
