DSPM will remain at the cutting edge of technology and convenience by having SNMP as an option on
its 3-phase 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,
currents, 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

(
Fax Modem
) is a " Telephone line managing devices on an IP
networks. Its standard features allow users to send a fax by using the telephone access of an E-mail
service, 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,
printers, 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
3-phase power supplies. The FAX will be able to send emails to interested parties when a problem with
the power 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 communica-
tion between a system that measures temperature, real power, load percentile, battery current, and fre-
quency, 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 3
-phase power supplies. Our lighting inverter are programmed to “talk Modbus”. DSPM’s lighting invert-
ers respond 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 an-
other 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
automatic dialer. If the output of the UPS goes off, the automatic dialer hooked to the normally “Off”
contacts will energize calling the maintenance telephone.
SRB
—Seismic-Rated Bracket
DSPM’s
Seismic-Rated Brackets
are built for use in seismic zone 0 through 4. DSPM’s Seismic-
Rated Brackets are Ideal for
blocking and strapping to foundation to hold UPSs in place in case of earth-
quake. Consult your local building code or official for information about local zoning laws.
STU3
—Onsite Startup
Onsite Startup
is an option that can be purchased along with all DSPM’s product when the stand-
ard
Telephone Startup
is not what you desire. When purchased, we send a qualified technician to your
site to do the startup.
EW
—Extended Warranty
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.
