ACS580-01-039A-4 18.5KW AC Drives 38A 400V

Overview

ACS580-01-039A-4 is an ACS580 series wall-mounted low-voltage general-purpose inverter with a rated output power of 18.5kW and a rated output current of 39A. The long-term current under heavy load (constant torque) operating condition is 39A. The light load (variable torque) operating condition can be adapted to a higher current range. The overload capacity is 150% for 1 minute. Three-phase 380-480V AC input. Input frequency 47.5-63Hz; output frequency 0-500Hz, circuit board coating design, dustproof and moisture-proof; operating temperature range -15℃-40℃, supports Drive composer debugging software.

FAQ:

1. How long can the 150% overload capability of ACS580-01-039A-4 be maintained? What are the threshold conditions that trigger overload protection?

ACS580-01-039A-4 150% overload capability lasts for 1 minute (based on 40°C, standard heat dissipation, rated voltage conditions).
Threshold conditions for triggering overload protection:

1. 150% rated current (58.5A) for more than 1 minute.
2. The heat sink temperature exceeds 100°C, or the ambient temperature is >40°C, resulting in overload derating.
3. The motor is stalled, has a heat dissipation failure, and the overload time parameters are incorrectly set.

2.When ACS580-01-039A-4 is adapted to an 18.5kW constant torque load, will the upper temperature limit for long-term operation be reduced? Do you need additional cooling devices?

When ACS580-01-039A-4 is adapted to a 18.5kW constant torque load, the upper limit of the reference temperature remains unchanged (it can operate in a 40℃ environment for a long time).

1. Normal working conditions: Standard air cooling + reasonable installation, no additional heat dissipation device is required.
2. Special working conditions (high temperature/enclosed/dusty): A cooling fan or cabinet cooler is required.

3.Can ACS580-01-039A-4 directly drive a motor with a braking unit?

ACS580-01-039A-4 cannot directly drive a motor with a braking unit. An external braking unit (such as the ABB NBRC-06 series) and a matching braking resistor must be selected, and the corresponding parameters must be wired through the braking terminals to consume the regenerative energy generated by motor braking to avoid overvoltage protection.
