characteristics

resistor Load Banks

High Current Oval Edgewound

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

Tolerance

±10%.

Terminals/Jumpers Standard terminals have 5/16 stainless hardware for ring lug con-

nections. Brass tags can be placed at connection points for iden-

tification. 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 con-

structed 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.

The choice when conditions demand top-notch per-

formance, 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 thirty-

one 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 termi-

nal supports. The resistance element is made of a

stainless steel resistance alloy. Terminals are welded

or silver brazed to the oval, spiral edgewound resis-

tance element. Toothed ceramic insulators isolate the

resistance element from the center support. Ceramic

end bushings insulate the center support from the

mountings.

NOTE

Load banks require

significant investment

in resistance wire due

to high minimum order

quantities imposed by

our vendors. Before

ordering always check
