The RZW02.1-110-060 from Bosch Rexroth Indramat delivers 100 kW peak power and a 100 s thermal time constant. Part of the RZW Braking Resistors series, it has 2.7 Ω resistance at 40% duty and IP23 protection. Housed in galvanized steel with an axial ventilator, it withstands non-condensing humidity below 90%.
It operates at 0 to 40°C with a 60% operating factor for continuous energy dissipation. Switch-on time at 60% duty reaches 72 s. The minimum connectable resistance is 2.5 Ω.
