Description

Normally, the DC link capacity handles braking, so an external resistor is not required. Only the intrinsically safe type with temperature monitoring function can be used. Supports frame sizes FSA to FSC, with resistance values of 50 to 150 Ω, rated output of 20 to 62 W, maximum output of 1.09 to 3.28 kW, and maximum energy of 0.8 to 2.46 kJ.

Features

  • Intrinsically safe design with temperature monitoring function
  • Three frame sizes, FSA to FSC

Applications

  • Large braking requirements of servo drives
  • Equipment with high regenerative energy
