Formula for brake resistor:
W= ( Vpnb * Vpnb ) * ED% / R
1.
W:
braking resistor power (Watts)
2.
Vpnb:
braking voltage (220V=380VDC, 440V=760VDC)
3.
ED%:
braking effective period
4.
R:
braking resistor rated ohms
5.
Alternative selection choice:
450: (JNTBU-430 + JNBR-4R8KW32)
2, 460: (JNTBU-430 + JNBR-4R8KW27R2)
2
Above 25HP, please add Braking Transistor Units: 200V JNTBU-230, 400V JNTBU-430, and 400V JUVPHV-0060
For more detailed information, please contact TECO.
When installing a braking unit and resistor, ensure that there is adequate clearance and ventilation.
