Feel the Power

ACQ580 drives are designed for customers who value reliability,

high quality, and robustness. With embedded pump functionality,

the ACQ580 keeps the pump system operating optimally and

efficiently. Product features, such as coated boards and optional

compact UL Type 12 enclosures, make the ACQ580 suitable for harsh conditions.

All ACQ580 drives are current-rated devices. The HP ratings

provided are for reference only and are based on typical

4-pole motors at nominal voltages (NEC Table 430.250). If

full motor torque is required, ensure the drive has a

continuous current rating equal to, or greater than the full

load amp rating of the motor.

The ACQ580 is available in both normal and heavy-duty

ratings. Normal duty ratings provide a 110% short term

overload rating for one minute every ten minutes. Heavy

duty ratings provide a 150% short term overload rating for

one minute every ten minutes. All ACQ580 drives and their

protective functions are thoroughly tested for optimal performance.

The drive is available in power ranges from 1 to 150 HP at 230V, 1 to

350 HP at 460V, and 2 to 250 HP at 575V. It is available in UL Type

(NEMA) 1 and 12 enclosures.

The ACQ580 is the latest addition to the ABB drives portfolio. 

This robust, compact and energy efficient drive is designed for

securing the flow of water and wastewater in your pumping system.

The drive is available in power ranges from 1 to 150 HP at 230V, 1 to

350 HP at 460V, and 2 to 250 HP at 575V. It is available in UL Type

(NEMA) 1 and 12 enclosures.

Secure the flow

The ACQ580 variable frequency drive (VFD) delivers innovative

pumping features for the water and wastewater industry. Primary

Setting menu and assistants simplifies commissioning, setup and

daily control. Embedded water and wastewater application

features create an intuitive environment for users and dedicated

pumping features enhance the performance of the pumping system.

Speak the language

Leveraging clear, water industry terminology, the control panel

enables operators to efficiently interface with the drives in terms

they use every day. The optional Bluetooth control panel allows for

wireless commissioning and monitoring.

Voting Units

The Voting Units SS822Z, SS823 and SS833 have been

specifically designed to be employed as a control

unit within a redundant power supply configuration. The output connections from two Power Supply

Units are connected to the Voting Unit. The Voting

Unit separates the redundant Power Supply Units, supervises the voltage supplied, and generates supervision signals to be connected to the power consumer.

Green LED’s, mounted on the front panel of the voting unit, provide a visual indication that the correct

output voltage is being delivered. Simultaneously

with the green LED illuminating, a voltage free contact closes the path to the corresponding “OK connector”. Voting Unit trip levels, are factory preset.

High Integrity

The AC 800M High Integrity and the connected S880

High Integrity I/O system (including field power)

shall be supplied from a SELV or PELV power supply

(e.g. SD83x) connected through the power voter

SS823. The SS823 Voting Unit has double overvoltage protection circuit, limiting the output voltage to

max 30 VDC. It is also able to detect both short and

open circuit in the voting element.

The SS822Z and SS823 units is also G3 compliant.

Key Features

• Simple DIN-rail mounting

• Class I Equipment, (when connected to Protective Earth, (PE))

• Over-voltage Category III for connection to primary main TN network

• Protective separation of secondary circuit from primary circuit

• Accepted for SELV and PELV applications

• The output of the units is protected against over

current (current limit) and over voltage (OVP)

• SD834 can be connected in parallel to increase output power

• Both a.c. and d.c. input at SD831 and SD834

• Floating DC-OK relay contact at SD834

Power Supplies

The SD83x and SD85x Power Supply Units are designed to meet all the applicable electrical safety

data stated by the EN 50178 harmonized European

Standard Publication and the additional safety and

function data required by EN 61131-2 and UL 508.

The secondary output circuitry is accepted for SELV

or PELV applications.

They are switch-mode Power Supply Units which

convert the mains voltage to 24 volts d.c. These

power supplies can be utilized for non-redundant

and redundant applications. Redundant applications

require diode voting units SS823 or SS832.

With the type SD83x series Power Supply Units,

there is no requirement for the installation of a

mains filter. They provide a soft start feature; power-on of an SD83x will not trip fuses or earth-fault

circuit breakers. The SD822Z is also G3 compliant.

The range also supports power supply configurations of the AC 800M and S800 I/O based IEC 61508-

SIL2 and SIL3 rated solutions. A Mains Breaker Kit for

DIN Rail is also available for our power supplies and voters.
