AFE2000 Series Active Front End Archives
Owner’s Manual
Delta Active Front End
AFE2000 Series Digitized Automation for a Changing World

Features

Full-load operation: input-side current THD lower than 5% and power factor up to 99%, reducing equipment capacity and installation cost
Lowers the excess heat generated by traditional brake resistors to reduce air-conditioning operation load
Energy-saving: more than 95% of the regenerative energy is converted into electricity and supplied back to the mains
AC motor drives with AFE2000: supports 4-quadrant operation with variable frequencies and adjustable system
Constant DC bus voltage: unaﬀected by mains voltage ﬂuctuations
Built-in Modbus RS-485 protocol: Modbus TCP communication card is available for equipment connection

Applications

Large-inertia loads: centrifuge equipment, dewatering machines and roving machines
4-quadrant loads: elevators, cranes and pumpjacks (oil extraction machines)
Quick braking: machine tools, bag making machines, auto storage and retrieval systems, and lathes
Long-term energy feedback: wind power, water power, steel printing and paper making machinery (winding equipment)
Improves power quality for industries such as semiconductor and panel industries

When unloading large goods or cargos, the crane’s motor is in generator mode and produces excess energy. The AFE2000 reduces the excess heat generated by a traditional brake resistor and converts the excess energy into reusable energy for the crane system.

When traveling upward with a light load or downward with a heavy load, the elevator’s motor is in generator mode and produces excess energy. The AFE2000 converts the excess energy into reusable electricity for the use of other devices and equipment.

THD<=5%, power factor > 99%
The AFE improves power factor and decreases harmonic distortion
Improves power factor, lowers harmonic distortion, and decreases energy consumption to reduce energy costs and protect the environment.
The AFE2000 is your best choice to comply with the following international standards:
IEEE519-1992
IEC/EN61000-3-12
IEC/EN61000-3-4
IEC/EN61000-3-2
Lowers the excess heat generated by traditional brake resistors with the AFE200 converting regenerative energy (excess heat) into reusable electricity and reducing air- conditioning operation load

Multiple Solutions

The AFE2000 Series is an energy-saving product that oﬀers a regenerative energy solution and at the same time improves overall power quality while reducing total electricity costs.

Wiring
One-to-One Installation (One AFE2000 + One AC Motor Drive)

Note:

Delta’s AC reactor (standard installation accessory) is equipped with a thermal protection function. The TH3 terminal will have the AFE2000 send out a warning message, when the reactor temperature exceeds 120 °C.
For one-to-many installation, it is recommended to install a fuse at the DC input side of the drive. Please calculate and select a suitable fuse for your drive: Fuse type= (Rated input current of drive / 0.78) x 1.5
For installing a non-Delta brand AC reactor, please connect the PLL power input terminals (r1/I1, s1/I2, t1/I3) to the power input terminals (R/L1, S/L2, T/L3).

LC Filter Wiring Diagram
The AFE LC ﬁlter enhances system power eﬃciency and suppresses frequency interference when matched with standard reactors and active front end units.

Delta’s AC reactor (standard installation accessory) is equipped with a thermal protection function. The TH3 terminal will have the AFE2000 send out a warning message when the reactor temperature exceeds 120℃ .
For installing an LC ﬁlter, please connect the AFE’s power input terminals (r1/I1, s1/I2, t1/I3) to the LC ﬁlter’s AC detection terminals (Us1, Vs1, Ws1).
