VFDB4030 | DELTA Brake Unit

DELTA’s VFDB braking units are applied to absorb the motor regeneration energy when the three-phase induction motor stops by deceleration. With VFDB braking unit, the regeneration energy will be dissipated in dedicated braking resistors. To prevent mechanical or human injury, please refer to this instruction sheet before wiring. VFDB braking units are suitable for DELTA AC Motor Drives VFD Series 460V. VFDB braking units need to be used in conjunction with BR series braking resistors to provide the optimum braking characteristics.Heat Sink Overheat Temperature over +95℃ (203°F)Alarm Output Relay contact 5A120VAC/28VDC (RA,RB,RC)Power Charge Display Blackout until bus (+~-) voltage is below 5oVDCInstallation Location Indoor (no corrosive gases, metallic dust)Installation Location Indoor (no corrosive gases, metallic dust)Operating Temperature -10℃~+50℃ (14°F to 122°F)Storage Temperature -20℃~+60℃ (-4F to 140°F)Humidity 90%Non-condensingVibration 9.8m/s2 (1G) under 20Hz 2m/s2(0.2G) at 20~50Hz
