Delta BR

Delta BR braking resistor 300 W 70 Ω

Delta 300 W / 70 Ω braking resistor for drives with a built-in brake chopper or a VFDB braking unit. Delta specifies it for MS300, ME300 models; it dissipates as heat the energy the motor returns during deceleration.

Features

  • Power 80 W to 1500 W, resistance 13 Ω to 750 Ω (in our list)
  • Resistance tolerance ±5%
  • Overload 10 × rated power for 10 s (10 s on / 90 s off)
  • Selected from Delta tables for 125% braking torque at 10% ED
  • Resistors can be combined in series/parallel for higher power
  • Oxidized aluminium housing (≤ 500 W) or wire-wound with ceramic coating (≥ 1 kW)

Delta BR brake resistors dissipate as heat the energy a motor returns during deceleration or fast stopping. They are used with Delta drives that have a built-in brake chopper (e.g. MS300, ME300, CP2000 up to 30 kW) or with VFDB braking units. Models up to 500 W have an aluminium housing; 1–1.5 kW models are wire-wound.
