Product Details

SFL24-24-100RED Product Description

The SOLA SFL24-24-100RED is a high-performance 24VDC industrial power supply from the SFL Series by Sola Electric, engineered to deliver stable, energy-efficient power to demanding automation environments. Designed for integration into smart production lines, this unit plays a central role in energy acquisition, load management, and equipment state feedback — enabling factories to reduce idle energy consumption, lower thermal loads, and maintain consistent production rhythm.

With a compact form factor and robust output regulation, the SFL24-24-100RED is built to support continuous-duty industrial applications where power quality directly impacts throughput, equipment longevity, and operational cost. Whether deployed in a new automation cell or used as a drop-in replacement in an existing control cabinet, this unit delivers the reliability and efficiency that modern energy management systems demand.

In a fully integrated automation architecture, the SFL24-24-100RED serves as the backbone power source for a wide range of control and monitoring components. When paired with a Siemens S7-1200 PLC or Allen-Bradley MicroLogix 1100, it provides the clean, regulated 24VDC logic power required for reliable scan-cycle execution and I/O response — directly reducing the risk of nuisance faults caused by voltage sag or ripple.

In drive-intensive applications, the SFL24-24-100RED supplies control-circuit power to ABB ACS550 variable frequency drives and Yaskawa GA700 series VFDs, ensuring that the drive's control board and communication interface remain energized independently of the main power bus. This separation of control and load power is a key strategy for reducing thermal stress and improving overall drive efficiency.

For servo-based motion systems, the unit provides stable auxiliary power to Mitsubishi MR-J4 servo amplifiers, supporting encoder feedback circuits and brake control outputs without introducing noise into the motion command path. This contributes directly to tighter positioning accuracy and reduced cycle-time variation — both critical factors in production line beat optimization.

The SFL24-24-100RED also integrates seamlessly with Phoenix Contact QUINT power monitoring modules and Schneider Electric PowerLogic PM5000 series power meters, enabling real-time energy acquisition at the panel level. By feeding clean 24VDC to these monitoring devices, the supply ensures accurate current and power factor readings — data that feeds directly into SCADA and energy management systems for load balancing and predictive maintenance scheduling.

On the field device side, the unit powers Turck Banner photoelectric sensors, Balluff BIS RFID readers, and distributed Beckhoff EtherCAT I/O terminals, maintaining consistent signal integrity across the production floor. Stable sensor power is essential for accurate machine state feedback, which in turn allows the control system to minimize unnecessary actuator cycles and reduce energy waste at the equipment level.

For operator interface applications, the SFL24-24-100RED supports Weintek cMT series HMI panels and Proface GP4000 series terminals, providing the isolated 24VDC supply needed for touchscreen operation and alarm annunciation without interference from motor-driven loads on the same panel.

Energy efficiency in industrial manufacturing is not achieved through a single component — it is the result of every element in the control architecture performing its role with precision and minimal waste. The SOLA SFL24-24-100RED contributes to this goal at the foundational level: by delivering tightly regulated 24VDC output with minimal ripple and low standby dissipation, it ensures that every downstream device operates within its optimal power envelope.

Voltage instability is one of the most common and underappreciated sources of energy waste in industrial panels. When control-circuit power fluctuates, PLCs execute additional error-handling routines, drives perform unnecessary fault resets, and sensors generate spurious signals that trigger unplanned actuator movements. Each of these events consumes energy without contributing to production output. The SFL24-24-100RED's regulated output eliminates this source of inefficiency, allowing the control system to operate in a steady, predictable state.

Thermal load management is another area where this unit delivers measurable value. Its convection-cooled design and high conversion efficiency mean that less input power is lost as heat inside the control cabinet. Lower cabinet temperatures reduce the duty cycle of cooling fans and air conditioners, extending their service life and cutting auxiliary energy consumption. In high-density panel installations, this thermal advantage compounds across multiple power supply units, resulting in significant aggregate energy savings.

From a predictive maintenance perspective, the SFL24-24-100RED's built-in protection features — including overcurrent, overvoltage, and short-circuit protection — provide an early warning layer that prevents catastrophic failures. When integrated with a SCADA system that monitors supply output voltage and current draw, maintenance teams can identify developing load imbalances before they cause unplanned downtime. Planned maintenance windows are far less costly than emergency shutdowns, both in direct repair costs and in lost production throughput.

For facilities operating under ISO 50001 energy management frameworks or pursuing carbon neutrality targets, the SFL24-24-100RED supports compliance by enabling granular, panel-level energy metering. Combined with power monitoring modules and a properly configured energy management system, it provides the data infrastructure needed to identify inefficient equipment, optimize shift scheduling, and demonstrate measurable energy reduction over time.

Every unit shipped from NANKMOS inventory undergoes outgoing quality inspection and functional load testing prior to dispatch, ensuring that the SFL24-24-100RED arrives ready for immediate installation. Backed by a 12-month warranty, this unit represents a low-risk, high-value investment in the energy efficiency and reliability of your production line.

Q1: What energy-saving benefits does the SFL24-24-100RED provide compared to standard industrial power supplies? The SFL24-24-100RED uses a high-efficiency switching topology that minimizes conversion losses and standby power draw. Its tightly regulated 24VDC output prevents downstream devices from drawing excess current to compensate for voltage sag, reducing overall panel energy consumption. Lower heat dissipation also reduces the load on cabinet cooling systems, contributing to additional indirect energy savings.

Q2: Is the SFL24-24-100RED compatible with my existing PLC and VFD control architecture? Yes. The SFL24-24-100RED is designed as a universal 24VDC control-circuit power supply compatible with the vast majority of industrial PLCs, variable frequency drives, servo amplifiers, HMI panels, I/O modules, and field sensors that operate on 24VDC logic power. Its DIN rail mounting and standard terminal block connections ensure straightforward integration into existing control cabinets without panel modification.

Q3: Can the SFL24-24-100RED be used as a direct replacement for other SFL Series or equivalent 24VDC supplies? In most cases, yes. The SFL24-24-100RED is a standard 100W / 4.2A 24VDC output unit within the Sola Electric SFL Series. It can serve as a direct replacement for other units with equivalent output ratings. For applications with specific inrush current, hold-up time, or redundancy requirements, we recommend verifying the full specification sheet against your system's power budget before installation.

Q4: What is the warranty coverage, and how does NANKMOS handle testing and stock availability? All SFL24-24-100RED units supplied by NANKMOS are covered by a 12-month warranty from the date of shipment. Each unit undergoes functional load testing and quality inspection before dispatch to ensure it meets specification. NANKMOS maintains active inventory of SFL Series components to support fast order fulfillment.
