| IRC's Dynamic Braking Resistors |
Thursday, May 29, 2008
LAS VEGAS, NV (May 6, 2008) -- Providing design engineers with a robust, ultra low profile braking resistor, IRC offers a family of thick film planar power resistors on insulated stainless steel substrates. Designated the WDBR Series, the dynamic braking resistor enables motion control systems designers to replace bulky wirewound devices with a low-inductance, flameproof, intrinsically safe planar device rated for ultra-high temperatures.
"The closely matched thermal expansion coefficients between the stainless steel and the dielectric film enable the resistor to withstand severe temperature cycling, particularly in high pulse applications," said Harold Warren, IRC's business unit director. "The WDBR Series exhibits superior dissipation capabilities, ability
to withstand thermal shock, high thermal transfer efficiency and exceptional mechanical robustness, providing a failsafe construction. This construction allows the resistors to be employed
in numerous applications requiring high pulse power ratings up to 7kW or continuous high power loads.
Typical applications for the WDBR Series braking resistors include dynamic braking of motors in motion control systems; battery pre-charge and capacitor discharge circuits in hybrid vehicles; and
voltage bus clamp and trickle-charge circuits in industrial electronics, UPS systems and heavy-duty battery backup systems.
Maximum pulse power for the dynamic braking resistors is 1.5kW, 2kW, 3.5kW, 5kW and 7kW. Resistance ranges from 12ohms to 150ohms, with tolerance to ±10% and a minimum dielectric withstanding voltage of 2500VDC. Inductance values range from less than 3µ to less than 6µ, with an operating temperature to 400°C. Custom designs and resistance values are also available.
