Ohmite HCLB-24-R165E High current oval edgewound Datasheet

Resistor Load Banks
High Current Oval Edgewound
The choice when conditions demand top-notch performance, these resistor load banks are commonly
used for dynamic braking on Transit applications
or where high current handling and wattage are
required. Ohmite's unique Oval Edgewound design
allows for more wattage in smaller a package.
Choose from four bank wattages with up to thirtyone current ratings per bank.
Built to perform in rugged environments, Ohmite
load banks feature corrosion resistant stainless
steel insulator supports, solid nickel terminals, and
special electroless nickel-plated solid copper terminal supports. The resistance element is made of a
stainless steel resistance alloy. Terminals are welded
or silver brazed to the oval, spiral edgewound resistance element. Toothed ceramic insulators isolate the
resistance element from the center support. Ceramic
end bushings insulate the center support from the
mountings.
characteristics
Current Rating Continuous duty as listed below.
Wattage Rating Continuous duty based on a 375°C temperature rise.
Working Voltage Limited to 1000 Volts if mounting is grounded. Special higher
voltage mounting is available.
Resistance ±10%.
Tolerance
Terminals/Jumpers Standard terminals have 5/16 stainless hardware for ring lug connections. Brass tags can be placed at connection points for identification. If necessary, all connections can be made on one side
of grid. Fixed tap terminals are also available. Jumpers between
resistors are nickel plated solid copper.
Mounting Resistor Banks can be produced in grid arrays of 2 x 4 to 4 x
4. All resistors in one grid are the same length. Frames are constructed of heavy gauge zinc plated steel. Either “bolt up” or
“bolt down” type frames are available. Frames may be grounded
if voltage potential is below 1000 Volts.

NOTE
Load banks require
significant investment
in resistance wire due
to high minimum order
quantities imposed by
our vendors. Before
ordering always check
with the factory on wire
availability.
