User Manual of TI120 Series Variable Frequency Drive
Brief Introduction Of TI120 Series VFD
Functions and Features
Compared with common products in the same industry, the product has smaller structure volume
and larger power density.
Design of wide voltage range: rated input three-phase AC 360-460V, wide voltage range can
reach 323V-528V.
Built-in DC reactor: built-in DC reactor of 160 kW~450 kW model.
More perfect built-in brake unit: built-in brake unit below 37kW, 37kW~132kW optional built-in
brake unit.
Fast and smooth wave-by-wave current limiting function can avoid over-current faults of frequent
variable frequency drive.
The perfect over-excitation function can inhibit the rise of bus voltage during deceleration process
effectively, avoid frequent reporting of over-voltage fault and realize fast braking under the
condition of not connecting the brake resistor.
V/F separation function can realize the using requirements of variable-frequency power source.
Perfect complete machine protection function, short-circuit protection to ground, output
short-circuit protection, short-circuit protection of various power supplies, etc.
