The Simplex dynaMITE is a large
capacity, high performance Portable
Load Bank designed to provide the
manufacturers, distributors and users of
large AC generators and UPS systems
with sophisticated testing capability.
dynaMITE Load Banks feature digital
controllers with network control and data
acquisition capability. Operator interface
is via touchscreen. Load control is via
screen keypad. All electrical values
display on the screen and are recorded
by the system for future data retrieval.
Any number of dynaMITE and Electra
Load Banks can be combined for large
system capacities and networked for
central control and data acquisition.
dynaMITE
Digital Load Bank with Data Acquisition
300KW - 400KW
The dynaMITE Series comprises models
rated 300-400kw of resistive load at
both 240V and 480V, 3-phase. It can be
applied at any AC voltage to 480V AC,
50-60 Hertz standard, single or 3-phase.
Load step resolution is 5KW.

Description
Simplex Load Banks utilize “PowrWeb” load elements. The “Powr-Web”
is an advanced design, air-cooled
power resistor specifi cally designed for
application to Load Bank systems. The
“Powr-Web” is conservatively operated
at half the maximum temperature rating
of the alloy and features a short-circuitsafe design based on continuous
mechanical support of the element by
high temperature, ceramic clad stainless
steel rods. The “Power Webs” are
assembled into discrete trays which are
assembled in a vertical “stack.” Each
tray in the “stack” is independently
serviceable without disturbing adjacent
trays.
Specifi cations
• Alloy: FeCrAl
• Maximum continuous temperature
rating: 1920°F
• Maximum operating temperature as
applied in Load Bank: 1080° F
• Cool down time from operating to
ambient temperature is 10 seconds.
Construction
• Ceramic clad, stainless steel throughrods.
• UL Recognized
