Application Scenarios
At a steel mill in South Korea,a sudden drive shutdown during a critical rolling pass caused a$500K loss in damaged material and production delays.Investigation revealed that a failing power supply had caused a voltage dip,leading to a logic reset in the main controller.After replacing the legacy unit with the 3BSE003389R1 SA168 power supply—known for its robust voltage regulation and transient immunity—the drive system achieved 99.98%uptime over the next 18 months.The 3BSE003389R1’s ability to maintain stable 24V output during voltage sags and electrical noise events proved essential in protecting the control ecosystem,turning a chronic failure point into a pillar of reliability.

Technical Principles and Innovative Values
Innovation Point 1:Universal Input with Wide Range
The 3BSE003389R1 supports both 100–240V AC and 120–300V DC inputs,making it adaptable to global power systems and backup DC supplies(e.g.,battery banks),ideal for offshore and remote installations.
Innovation Point 2:Fanless,Convection-Cooled Design
Unlike many industrial PSUs,the 3BSE003389R1 operates without a fan,eliminating a common failure point and reducing dust ingress.This design enhances reliability in high-temperature,high-dust environments like steel mills and cement plants.
Innovation Point 3:High MTBF&Long Service Life
With an MTBF exceeding 100,000 hours,the 3BSE003389R1 is built with premium-grade electrolytic capacitors and robust circuitry,ensuring long-term operation without degradation—critical for 24/7 industrial processes.
Innovation Point 4:Comprehensive Protection Suite
Integrated protection against overload,short-circuit,overvoltage,and overtemperature ensures fail-safe operation.The unit automatically recovers after fault clearance,minimizing manual intervention.
Application Cases and Industry Value
In a water treatment facility in Australia,frequent power supply failures in the pump drives led to inconsistent flow control and emergency bypass operations.The facility upgraded to the 3BSE003389R1 SA168 across all critical drive cabinets.Over the next two years,there were zero power-related drive faults,even during summer heatwaves when ambient temperatures exceeded 55°C.Maintenance teams praised the unit’s consistent performance and ease of replacement.The 3BSE003389R1’s wide operating temperature range and convection cooling were decisive factors in achieving uninterrupted water supply,directly supporting public health and regulatory compliance.
