DSPM will remain at the cutting edge of technology and convenience by having SNMP as an option on
its power supplies. The SNMP will be able to send emails to interested parties when a problem with the
power supply occurs. The SNMP will host a java webpage that shows all the relevant voltages, cur-
rents, powers, energies, times, alarms, associated with the power supply. The operator will also be able
to remotely operate the power supply as if they are standing in front of it pushing buttons.

(
Fax Modem
) is a "Telephone line managing devices on an IP net-
works. Its standard features allow users to send a fax by using the telephone access of an E
-
mail ser-
vice, and receive incoming and send outgoing faxes via E
-
mail with the Fax content presented as a file
attachment.
”
Devices that typically support FAX include routers, switches, servers, workstations, print-
ers, and more.
A fax modem enables a computer to transmit and receive documents. A fax modem is like a data mo-
dem but is designed to transmit and receive documents to and from a fax machine or another fax mo-
dem. Some, but not all, fax modems do double duty as data modems.
UPS and Emergency Lighting Inverter manufacturers have adopted the FAX to allow users to easily
communicate with their UPS systems via a telephone line. FAX makes it possible for node network
communicate with the UPS systems to send out emails to anyone on the network, if an email server is
available.
DSPM will remain at the cutting edge of technology and convenience by having FAX as an option on its
power supplies. The FAX will be able to send emails to interested parties when a problem with the pow-
er supply occurs.
MB
—Modbus Interface
Modbus Interface
is a serial communications protocol that is simple and robust for connecting industrial
electronic devices. Modbus is often used to connect a supervisory computer with a remote terminal unit
(RTU) in supervisory control and data acquisition systems. Modbus allows for communication between
a system that measures temperature, real power, load percentile, battery current, and frequency, and
communicates the measured results to a computer.
DSPM will remain at the cutting edge of technology and convenience by having MB as an option on its
power supplies. Our lighting inverter are programmed to
“
talk Modbus
”.
DSPM
’
s lighting inverters re-
spond to commands send through TCP Modbus. We use a gateway that converts the Ethernet physical
layer into a RS232 physical layer which our control board uses. With the use of MB, the user will be
able to monitor normal operation and know when problems occurs with the UPS or its load (s).
FC
—Form C Contacts
Form C Contacts
is an option to be used when it is necessary to turn on or off one device by another
device. This is done by the Form C Contacts control of two circuits: one normally
-
open contact and one
normally
-
closed contact with a common terminal. One use of Form C Contacts may be with an automat-
ic dialer. If the output of the UPS goes off, the automatic dialer hooked to the normally
“
Off
”
contacts will
energize calling the maintenance telephone.

Onsite Startup
is an option that can be purchased along with all DSPM
’
s product when the standard
Telephone Startup
is not what you desire. When purchased, we send a qualified technician to your
site to do the startup.
EW

Extended Warranty
is for one (1) year onsite parts and labor.
OCB
—Output Circuit Breaker/(s) 120Vac or 277Vac
Output Circuit Breaker/(s)
are an excellent feature for separating and controlling the load in the UPS.
Furthermore, the controlling of the individual branches that constitutes your load can be done while the
UPS is running, giving the customer multiple options or ways to use their UPSs.
