Mobile DC UPS
Mobile Data Power System
The Mobile Data Power, model MDP-25, is a DC UPS that solves
the common problem of lengthy reboot sequences, system crash, data and hard
drive corruption in mobile computer work stations due to a low voltage and loss
of power as a result of intermittent or poor vehicle battery condition. In
addition, the MDP provides a low voltage output warning signal to terminals
(such as Motorolaฎ MW 800 series work stations) allowing orderly automatic
shutdown of the powered device, protecting data and preventing hard drive
corruption.
Utilizing a high speed sensor circuit, when primary vehicle
voltage drops below a critical point, the internal 9AH battery is switched
on-line in milli-seconds, assuring no interruption to the powered device(s). The
MDP-25 has an internal 3 step, temperature compensated charger that maintains
its reserve battery at full charge, ready to go on-line when a fault or
degradation of primary vehicle battery occurs. This functionality assures
continued operation of mobile computers under a variety of adverse vehicle
battery conditions.
Housed in a rugged aluminum case and heavy duty mounting
plate, the unit is designed for installation in emergency vehicles, service and
other utility vehicles that require a steady source of voltage for mobile
computers, work stations, and electronics.
Protects mobile computers
against system crash, lengthy reboot
sequences, and loss of data due to:
Voltage dip during engine cranking
Voltage drop and decay due to loading high power accessories, and aging
batteries
Voltage loss due to cycling of master disconnect switch and battery failure.
Provides supplemental voltage
in milli-seconds to mobile data devices
when low vehicle battery is sensed.
Immediately augments power to electronics when needed and fully powers
electronics
if critical low voltage condition persists.
Built-in Multi-Stage filter
provides clean power required by mobile electronics
Eliminates noise and interference
Transient protection prevents damage to sensitive circuitry due to voltage
spikes
Provides output warning signals
to mobile computers (such as Motorolaฎ
MW 800 series work stations)
Initiates low voltage shut down sequence in mobile computer, protecting data
and hard drive.
Alerts when system is operating on battery back-up
Internal 3 stage, temperature
compensated charger maintains back-up
battery in fully charge stand-by state.
