| Dimensions |
200.5 × 69.5 × 35 mm (L × W × H); case 981A. Drawing tolerance: ±1 mm. |
| Construction |
Plastic enclosure with terminal-block input and output. |
| Mounting drawing references |
The drawing shows two R2.5 mm and two R9 mm open mounting features, 6.26 mm end offsets and 20.2 mm edge offsets. |
| Case-temperature measuring point |
The Tc measuring point is 100.25 mm from the right end and 34.75 mm from the lower edge in the top view. These are location dimensions, not a case-temperature rating. |
| Input and output terminals |
TB1: pin 1 FG, pin 2 AC/N, pin 3 AC/L; SWITCHLAB MB310-75003. TB2: pin 1 +V, pin 2 −V; SWITCHLAB MB310-75002. |
| Output adjustment controls |
Vo ADJ adjusts output voltage; Io ADJ adjusts output current. |
| Switching frequency |
100 kHz. |
| Load application |
Suitable for LED lighting and moving signs, subject to the application restrictions stated here. The output characteristic graph has a constant-voltage area A for LED-driver loads, a constant-current area B for direct LED drive, and a hiccup area C. The constant-current region is 75–100% of rated voltage. |
| Constant-current compatibility |
The highest operating voltage in constant-current mode depends on the end-system configuration. Contact MEAN WELL if compatibility issues arise. |
| Efficiency graph scope |
The efficiency-versus-load graph illustrates the 48 V model at 115 VAC and 230 VAC; use the model-specific typical efficiency listed above for this selection. |
| Accessory scope |
The terminal part numbers identify the connector references in the drawing. No dedicated MEAN WELL accessory order code is specified in these series pages. |
| Packing and weight |
520 g catalog packing reference per unit, not a measured net weight. 25 pieces per carton; 14 kg per carton; 0.65 CUFT. |
