FAE Expert Insights
"The DPA60-24 is our favorite for small control panels where space is at a premium. The 22mm width is incredibly compact - you can fit multiple units on a single DIN rail. Despite the small size, it delivers reliable 60W with good efficiency. We use these extensively in building automation and small machine control panels. The 450K hour MTBF is excellent for this size class. For distributed I/O systems and compact PLCs, this is our standard recommendation."

Frequently Asked Questions
How compact is the DPA60-24 compared to other DIN rail supplies?
The DPA60-24 is exceptionally compact at only 22mm wide: DPA60-24: 22mm width; DPF120-24S: 40mm width; DPF240-24S: 40mm width; Competitor 60W: typically 35-45mm width. This means you can fit nearly two DPA60-24 units in the space of one typical competitor supply. The compact size is achieved through high-density design and efficient thermal management. For space-constrained panels, the DPA series offers significant space savings.
22mm width is among the most compact available. Contact us for space-saving panel designs.
What applications is the DPA60-24 best suited for?
The DPA60-24 is ideal for: Small control panels with limited DIN rail space; Distributed I/O systems requiring multiple power supplies; Building automation with many small loads; Security and access control systems; Compact PLCs and controllers; Sensor networks. The 60W output is sufficient for: Small PLCs (10-20W); Multiple sensors (5-15W); Small HMI panels (15-25W); Distributed I/O modules (10-20W). For applications requiring more than 60W, consider the DPF series. Contact our FAE team for power budgeting assistance.

Does the compact size affect reliability?
Despite the compact size, the DPA60-24 maintains high reliability: MTBF of 450,000 hours is excellent; Uses same quality components as larger supplies; Conservative derating ensures long life; Comprehensive protection prevents damage. The compact design uses: High-frequency switching for smaller magnetics; Advanced thermal management; Quality components rated for industrial use. Reliability is comparable to larger supplies. The 5-year warranty reflects Cosel's confidence. Contact our FAE team for reliability data.

Can I mount the DPA60-24 horizontally?
The DPA60-24 is designed for vertical DIN rail mounting (rail horizontal, supply vertical). This orientation provides optimal natural convection cooling. For horizontal mounting (rail vertical), derating is required: Typically 20-30% power reduction; Higher ambient temperature limits; May require forced air cooling. Best practice is vertical mounting on horizontal DIN rail. If horizontal mounting is required, contact our FAE team for thermal analysis and derating recommendations.
Vertical mounting preferred. Horizontal requires derating. Contact us for thermal analysis.
What is the startup time of the DPA60-24?
The DPA60-24 startup characteristics: Output rise time: <100ms from AC application to full output; Power good delay: 200-500ms after output stable; Hold-up time: 15ms typical at 230VAC. For systems requiring sequenced startup: Multiple DPA60-24 units can be synchronized; External sequencing circuits can control startup order; Power good signals indicate when each supply is ready. The fast startup ensures quick system availability. Contact our FAE team for startup sequencing design.
