The IRV(V=Vertical) & IRH(H=Horizontal) models are our standard wire wound, metal-
clad resistors. The ULV and ULH models are UL approved versions of the IRV and IRH.
These models have an extruded aluminum housing providing strong and rugged
protection. Options include flying leads or tab terminals, inductive or non-inductive
windings. The most common appl ications for theses models are: Motor drives, braking
and snubber applications and power sources for industrial equipment.

The IRN(N=Narrow and flat) & IRF(F=Flat) models are metal-clad, wirewound, high-power,
low inductance resistors designed for industrial and other applications where space is at a
premium and performance is a must. The ULN and ULF are UL approved versions of these
models. All of these models use an extruded aluminum housing providing rugged and strong
protection. The flat design allows excellent heat dissipation. These models are available
with flying leads or tab terminals. The most common applications for these models are:
Motor drives, braking and snubber applications and power sources for industrial equipment.

ORDERING PROCEDURE EXAMPLE
Thermostat options are available for these models
These economical and powerful components comprise two, three or four high power
resistors housed in partial steel covers at each end. These rugged, powder coated covers
ensure an excellent seal. The internal resistors use aluminum plates at each end instead
of our standard cement molding. This innovation reduces construction time and reduces
cost, at no reduction of performance. The major application of this exciting new model is
high power inverter braking units.

The HRA series of high power, metal clad, wire wound resistors are designed for use in high power inverters. The basis for these models are sets of IRV resistors surrounded by a metal case, which conforms to international safety specifications. The steel case is powder coated and baked for durability
The EW series of metal clad edge wound resistors are designed for use in super high power inverters. The basis for these models
are edge wound elements, surrounded by a metal case, which conforms to international safety specifications. The steel case is powder
coated and baked for durability.

The DBRI is for indoor use; DBRO is for outdoor use. The DBRO internal structure is the same as the DBRI The DBRO has a watertight external structure
The Power rating is based on a 375 rise above an ambient of 40

RARA manufactures load banks, ranging from small portable units for testing generators to multi-megawatt designs for
larger applications. Regular load testing, along with correct battery maintenance, is the best way of ensuring the reliability
of standby power systems. It is routine for all newly-installed generating sets to have a load test during the commissioning
process in order to prove the performance of the set and all its ancillaries-cooling system, exhaust system, switchgear
and protection schemes.
