ABB QUINT-PS/3AC/24DC/20 Configuration

The ABB 3BHE031065R0020 configuration is based on the QUINT-PS/3AC/24DC/20 power-supply architecture. It converts an applicable three-phase AC input into a controlled DC output suitable for industrial automation and drive-system auxiliary circuits.

The nominal output is 24 V DC at 20 A, giving a rated output power of 480 W. The output voltage can be adjusted between 18 V DC and 29.5 V DC, although operation above the nominal 24 V level has corresponding output-capacity considerations.

This combination of voltage and current makes the unit suitable for circuits requiring more auxiliary power than a small control-power supply can provide. The actual load must always remain within the applicable electrical and thermal limits.

Three-Phase AC Input

The QUINT-PS/3AC/24DC/20 design uses a three-phase AC input. Technical documentation for the corresponding power-supply configuration specifies a nominal input range of 3 x 400 V AC to 500 V AC, with an AC input operating range extending from 3 x 320 V AC to 575 V AC. The documented AC frequency range is 45 Hz to 65 Hz.

The power supply can therefore operate within a broad industrial AC input environment. The applicable input configuration and protection arrangement should be confirmed against the electrical drawings of the ABB drive system before connection.

The documented input structure is particularly relevant to industrial installations where auxiliary power is derived from a three-phase AC distribution system.

24 V DC Output

The primary output of ABB 3BHE031065R0020 is 24 V DC with a nominal current rating of 20 A. The resulting nominal output power is 480 W.

Twenty-four volt DC power is widely used in industrial automation for control equipment, interface circuits, relays, monitoring devices, communication equipment and other auxiliary loads. In an ABB drive system, the power supply can provide the DC energy required by designated control and auxiliary circuits.

The output voltage adjustment range of 18 V DC to 29.5 V DC provides flexibility for applications with specific DC supply requirements. Any adjustment should be made according to the requirements of the connected equipment.

POWER BOOST Function

The QUINT-PS/3AC/24DC/20 configuration includes a POWER BOOST function that allows a higher temporary or specified operating current under defined conditions. Technical documentation specifies a POWER BOOST current of 26 A at 24 V DC within the stated temperature range.

POWER BOOST is useful for loads that require additional current during startup or transient operating conditions. This capability can help support equipment with higher initial current demand without changing the basic 24 V DC supply architecture.

The POWER BOOST function should not be interpreted as a continuous unrestricted 26 A operating rating. The applicable temperature, output voltage and operating conditions must be observed.

Selective Fuse Breaking Technology

The corresponding QUINT POWER configuration incorporates Selective Fuse Breaking technology. Technical documentation specifies an SFB current of up to 120 A for a 12 ms period under the defined conditions.

The purpose of this function is to provide a high short-duration current capability that can help downstream protective devices respond selectively to short-circuit conditions. This approach can support continued operation of unaffected circuits in a properly designed industrial control system.

Protection coordination must nevertheless be established according to the complete electrical system design.

DC OK Monitoring

ABB 3BHE031065R0020 provides DC OK monitoring for supervision of the output condition. The power supply uses status indication to show whether the output voltage has reached the defined operating level.

The corresponding QUINT POWER documentation identifies a green DC OK LED and additional signaling options. This allows the power supply condition to be monitored locally and, depending on the configuration, through an external control circuit.

Monitoring the DC output status can be useful when diagnosing a drive-control system because a loss of auxiliary DC power can affect multiple electronic functions simultaneously.

Technical Specification

The listed specifications correspond to the QUINT-PS/3AC/24DC/20 configuration associated with ABB article number 3BHE031065R0020. ABB product information identifies the article number and type designation, while technical documentation for the corresponding QUINT POWER configuration provides the electrical characteristics. :contentReference[oaicite:1]{index=1}

Application in ACS1000 and ACS2000

ABB product records associate 3BHE031065R0020 with ACS1000 and ACS2000 drive systems. These systems contain multiple control, power-conversion and auxiliary circuits that require coordinated electrical supplies.

The power supply provides an auxiliary 24 V DC source rather than performing the primary motor power-conversion function. Its role is therefore complementary to the main drive power section.

The exact circuits supplied by the unit depend on the specific drive configuration, cabinet design and electrical documentation.

Industrial Control Integration

A stable auxiliary DC supply is essential to many industrial automation architectures. Controllers, interface devices, relays, monitoring circuits and communication equipment can depend on a controlled DC voltage.

The 24 V DC output of ABB 3BHE031065R0020 provides a common industrial control voltage while the 20 A capacity allows the supply to support a relatively substantial group of auxiliary loads.

When integrating the unit into a control cabinet, the connected load, conductor sizing, protective devices and grounding arrangement should be evaluated as a complete system.

Parallel and Series Connection

Technical documentation for the QUINT-PS/3AC/24DC/20 configuration permits parallel connection for redundancy or increased capacity and also permits series connection. These capabilities can be useful when an industrial control architecture requires greater availability or a different DC voltage arrangement.

Parallel operation should be designed according to the manufacturer’s connection requirements and load-sharing considerations. Series operation likewise requires the complete system to remain within the applicable insulation and voltage limits.

The presence of these connection options provides additional flexibility for industrial power-system design.

Physical and Installation Characteristics

The corresponding QUINT POWER unit uses a compact industrial enclosure intended for control-cabinet installation. Technical documentation specifies a width of approximately 69 mm, a height of 130 mm and a depth of 122 mm for the standard mounting arrangement.

The unit uses screw connections for input, output and signal circuits. The corresponding documentation specifies conductor cross-section ranges and M4 screw connections for these terminals.

Installation dimensions and terminal requirements should be checked against the actual equipment configuration before mounting or wiring.

Maintenance and Troubleshooting

When diagnosing ABB 3BHE031065R0020, the input supply should be checked first according to the applicable electrical safety procedure. If the input voltage is outside the specified operating range, the output condition may not represent a power-supply fault.

If the correct input is present but the expected 24 V DC output is unavailable, the connected load, output wiring and protection circuits should be evaluated systematically. An excessive load or downstream short circuit can influence the output condition.

The DC OK indication can provide an additional diagnostic reference. Any troubleshooting work must follow the safety requirements applicable to the associated medium voltage drive installation.

Engineering Documentation

For engineering databases, the recommended identification format is “ABB 3BHE031065R0020 — QUINT-PS/3AC/24DC/20 — Power Supply.”

The associated drive model, cabinet reference, input source, output circuit and installation location can be stored as additional engineering fields. Keeping the complete ABB article number unchanged is important because similar 3BHE components can have completely different functions.

Component Identification

ABB 3BHE031065R0020 should not be confused with other ABB power-supply articles. The exact type designation QUINT-PS/3AC/24DC/20 identifies the three-phase input and 24 V DC, 20 A output configuration.

This distinction is especially important when working with ACS1000 and ACS2000 systems, where multiple auxiliary power components can be installed in the same equipment.

The article number, type designation and associated drive model together provide a strong technical identification reference.

ABB 3BHE031065R0020 is the QUINT-PS/3AC/24DC/20 power supply identified in ABB product information. It is associated with ACS1000 and ACS2000 drive systems and provides an auxiliary power function within industrial drive and automation architectures.

The documented configuration uses a three-phase AC input and provides 24 V DC at 20 A, corresponding to 480 W of nominal output power. The output can be adjusted from 18 V DC to 29.5 V DC, and the POWER BOOST function provides up to 26 A under specified operating conditions. Additional functions include DC OK monitoring, selective fuse breaking technology and options for parallel or series connection. :contentReference[oaicite:2]{index=2}
