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 IRV & ULV 600~1200(V=Vertical) models are our standard higher power wire wound,

metal-clad resistors. The ULV 600~1200 is the UL approved version of the IRV600~1200

models. 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 applications 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

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.
