Dynamic Brake Resistor, 80 Ohms, 900 Watts

Dynamic Braking Resistor rated at 80 Ohms x 900 Watts @ 40 seconds based on a duty cycle of 120 seconds without using a heatsink.
Tolerance ±10% or better

Watts @ 20ºC without heatsink 250 W
1   Sec Watt 10000
10 Sec Watt  2500
40 Sec Watt 900

Temperature range -55 to 275ºC max.@ 20ºC ambient.
Short term overload 5X wattage for 5 seconds (Derate linearly at 275ºC)

Temperature rise @ 20ºC ambient for 100-400W for this range = 275ºC plus ambient wattage.
This can be increased by mounting the resistor on a heatsink. Above 275ºC derating is required

Dimensions: 320mm long x 15mm high x 76mm wide.

Flying lead connection 300mm
