Rectifier. Converts alternating current and voltage to direct current and voltage.
1
DC link. DC circuit between rectifier and inverter.
2
Inverter. Converts direct current and voltage to alternating current and voltage.
3
Brake chopper. Conducts the surplus energy from the intermediate DC circuit of the drive to the brake
resistor when it is necessary and if an external brake resistor is connected to the drive. The chopper op-
erates when the DC link voltage exceeds a certain maximum limit. The voltage rise is typically caused
by deceleration (braking) of a motor. The user obtains and installs the brake resistor when needed.

Product variants
The drive has two product variants:
•
Standard unit: drive (for example, ACS480-04-02A7-4) with ACS-AP-S assistant control
panel and I/O & EIA-485 module (RIIO-01).
•
Base unit: drive (for example, ACS480-04-02A7-4+0J400+0L540) without control panel
and without I/O & EIA-485 module (RIIO-01).

IEC and UL (NEC) product types
The ACS480 series consists of IEC product types and UL (NEC) product types. The IEC
types are designed for global use. The UL (NEC) types are specifically designed for use in
North America.
