Network Power Monitor R10 SNMP
Mi
The NPM-R10 (NETWORK POWER MONITOR R10) was designed to assist Network
and Wireless Network specialists with Power related information via Ethernet and
GSM Communication.
Total Battery Voltage as well as separate Battery voltages for series connected
Battery banks, Charging Current, Load current to equipment, Mains 220Vac Status,
1x External 100Vdc input , Alarm input and temperature information is available via
web pages, SMS and SNMP.
Embedded Web pages for monitoring and configuration of the system.
The unit supports the SNMP V1 and SNMP V2C communication platform to be
compatible with SNMP monitoring software platforms.
The NPM-R10 is powered by C language firmware and the code was written to
function as a co-operative RTOS.(Real time operating system)
2x16 LCD display onboard for quick access and indication of power related
information on site
Indicating :
(B:) Total Battery pack voltage
(Mains :) ON or OFF
(I:) Charge current
(i:) Load current - in case of alarm active (i:) will be replaced with (AL) for Alarm

2. BOARD CONNECTIONS
The NPM-R10 can work from a single 12V , 24V , 36V or 48V system
Wiring between batteries if more than 1 Battery can be a large gauge and is
customer defined by the amount of amps required by the charger and load
system
The wiring from – (ground) and each batteries + (positive) to the NPM-R10 can
be a small (thin) gauge wire as the NPM-R10 does not consume large currents
and only sense the battery voltages from here
Current consumption in total with LAN port connected 110mA @ 12Vcdc / 55mA
@ 24Vdc

Connections. (Important Please Read)
Connect GND (-) of the Battery system to the left hand side terminal marked
“GND”
The system will operate from 12 , 24 , 36 or 48V battery voltages
Connect the first battery (+12v) of the pack to Terminal “ 12+”
Connect the second Battery if 24V system (+24v) to Terminal “24+”
Connect the Third battery if 36V system(+36v) of the pack to Terminal “ 36+”
Connect the Fourth Battery if 48v system (+48v) to Terminal “48+”
The 12+ up to 48+ wires and the GND wire can be thin eg. 0.5mm wires as the current
consumption of the device is low.
Thick wires should be used for charge current and load current feed through depending on
the current requirement of your equipment.
Connect The Charger + to the Charge terminal marked “Charger+ IN”
Connect the terminal marked “+Charger out” to your battery pack main +
External Temperature sensor can be extended away from the board with 3 wires – range : 10 to +125 Deg C
**** IMPORTANT NOTE****
The Alarm input is a potential free contact input only and NO
voltages should be injected here- Permanent Damage to the
unit will occur.

P a g e
Network Power Monitor R10 SNMP
Mi
The current feed through for “LOAD” current and Charge current is two isolated
current ports. +Charge out can be bridged as above to + Load in as both comes
from the Battery pack main +
V1 External Vdc input can be used to monitor eg. Output of DC-DC converters or the
output voltages from Solar Panels etc.
The external 0-100 Vdc input is polarity protected on the board and the customer
can wired + and – for the input in any way.
The input is protected by a 110V TVS diode for spikes and over voltage
The Battery power input , 0-100VDC external input and the 220Vac Mains input is
surge and over voltage protected.
After the Alarm is triggered the (i:) indication of the Load current in the bottom right
corner of the LCD will change to AL: to indicate the Alarm condition.
The Alarm SNMP (OID) data will change from a 0 to a 1 , as soon as the Alarm input
is restored the screen will be cleared from AL: for alarm and return to i: for Load
current indication but the Alarm SNMP OID will stay at data 1 for about 20 sec after
the alarm was cleared.
This is working well with PIR alarm detectors etc so that the alarm condition is not
missed by the SNMP manager software

4. Relay Expansion board
The 5 Relay expansion board connects to the NPM-R10 via a 10way ribbon cable
supplied with the relay board
Relay 1,2,3 can only be toggled to activate for 10sec then return to the off position
again and is used to reset devices.
Relay 4 and 5 can be controlled to the ON or OFF position by the user and will keep
the selected position until changed by the user.
The status of all 5 relays is displayed on the home page of the unit by means of
green dots
In the “Relay” control page the user can assign names to the relays to help
remember what is connected to the relays at the remote site.

GSM module and functions
**FREE ANDROID APP TO DOWNLOAD ON THE GOOGLE PLAY STORE –
Search for “Mi GSM controller”
The Android application makes it easy to save multiple cell numbers with user
defined names for each number
Also because relay wiring would not be the same at each site user defined names
can be saved to each relay in the app under each specific site
Select NPM R10 GSM in app for this model
The NPM-R10 GSM module interfaces to the main board via a 20way ribbon cable and no
other connections are necessary.
The 4 way dip switch on the printed circuit board allows the user with the following:
Switch 1 – (ON) – SMS will be send if mains fails and when mains returns
Switch1 – (OFF) – NO SMS will be send regarding mains status
Switch 2 – (ON) – SMS will be send if the Alarm input on the NPM-R10 main
board goes open circuit
Switch2 – (OFF) – NO SMS will be send regarding Alarm status
Switch 3 – (ON) – SMS will be send if Battery volts falls below a certain level,
Auto calculating (11.5V for 12v system)- (23.0V for a 24V system) – (33.5V for a 36V
system ) and (46.0V for a 48V system)
Switch 3 – (OFF) – NO SMS will be send regarding Battery status
Switch 4 – (ON) – SMS will include the status of Relay 4 and Relay 5 if on or off
Switch 4 – (OFF) – SMS will not include Relay status in the message
If all dip switches is to the on position on the GSM board the user(s)will automatically
receive a SMS in case of an Alarm, Mains failure and Battery low condition
