GENERAL CHARACTERISTICS
These are high quality wire resistors in an aluminium container with a standard IP54 level of protection.
They are produced specifically for integration in command and control equipment for motors, such as INVERTERS, etc.
Ideally, they are mounted in contact with the inverter heat sink or a metallic wall of the cabinet, which ensures maximum performance of the resistors.
The particular shape and construction allow use of the maximum quantity of the active part, thus providing the possibility to absorb a great quantity of energy for adiabatic impulses and, at the same time, obtain a high level of nominal power.
All of the materials making up these resistors are fireproof and the winding, in particular, has been immersed in a mass of high thermal conductivity cement, which provides high insulation and is completely insensitive to humidity.
- Standard tolerance: ± 5%· Temperature coefficient: < 100 ppm/°C
- Maximum applicable voltage: 1000 V
- Standard length of cables: 250 mm
- Terminations on Cu/Ni cables with silicone anti-tear protection
- Filling with high thermal conduction inorganic materials
- Resistive element in alloy with a high NICKEL content
- Power cable length as required
- Application of a NC KLIXON type thermal contact
- Ohm values on request, compatibly with production
- Screened power cables
