CCP: new wide ohmic value range braking resistors

 

 

Braking resistors for applications where high ohmic values are needed, CCPs are the ideal solution for low power inverters requiring a resistor with value of hundreds of ohms, to be mounted either standing alone or onto a heat sink, even inverter integrated.

Their insulated body fixed to a thick stainless steel base make CCP resistors rugged and long lasting, with an extremely remarkable price/performance ratio.

 

 

Main features

- low cost

- high ohmic values

- heat sink mounting

- easy mounting

- ROHS compliant



HLR: compact and noiseless, the next generation resistors for up to 40kW inverters

 

The next generation heavy duty power resistors for extremely demanding applications: characteristics of HLR resistors are high protection grade, from standard IP44 to special IP67, extreme energy absorption capability and a new patent pending heat sink which makes them the highest power density resistors available on the market. Cabling can be performed in the embedded terminal case, high temperature cables are suggested.

Compact and noiseless, HLR resistors are the ideal solution for lift and crane industry, replacing with improved performances traditional metallic box resistors, for applications with up to 40kW inverters.

This special version of RFH series is supplied with a ceramic mammoth, allowing a simple and quick installation such as total flexibility for the choice of cables, thus being the ideal solution when shielded cables are required.

Main features
- simple installation
- suitable for the employment of shielded cables
- low thermal resistance
- excellent performances/dimensions ratio
- high protection degree
- noiseless
- ROHS compliant



BRV: a new patent pending resistor system

 

The continuous process of Research & Developement sustained by I.R.E. has led to a new solution that, with a size reduced to 50%, overcomes the present performance limits of medium-high power resistors: this is the BRV series.

 

 

 

The outstanding performances of BRV resistors are granted by an innovative patent pending concept of natural convection, which applies a new approach to the relationships among shape, position and nature of resistors, their enclosure, performances and working temperature.

 

 

 

High powers (from 20 KW) can therefore be placed in extremely reduced enclosures: a system of 120 KW power rating with degree of protection IP23 has normally a volume of 1000-1200 litres, whereas a BRV system can give the same performances with degree of protection IP24 in a volume of only 600 litres (in the picture), that means a double power density.
