  MEAN WELL IRM-45-24 is an encapsulated industrial AC/DC power module with PCB mounting, 24 V output, 1.9 A continuous rated current and 45.6 W rated output power under the specified conditions. It uses free-air convection cooling and Class II insulation without an FG pin. Product Datasheet Download MEAN WELL IRM-45 Datasheet (PDF) The IRM-45 section is on PDF pages 29, 30, 31, 32. Refer to the complete mechanical drawings and notes when planning installation. Model Code and Construction Complete model IRM-45-24 Series IRM-45 industrial AC/DC power module. Output code 24 V nominal DC output. Mounting suffix No suffix means PCB mounting style. Housing 94V-0 flame-retardant plastic case with silicone potting for heat dissipation and fundamental resistance to dust and moisture. Typical applications include industrial electrical equipment, mechanical equipment, factory automation and handheld electronic devices. Select the actual mounting version when designing the assembly; the PCB and ST versions have different dimensions, connections, weight and vibration ratings. Output Ratings and Performance Nominal DC voltage 24 V. Continuous rated current 1.9 A. Catalogue-rated output power 45.6 W. Output current range 0–1.9 A. Ripple and noise, maximum 200 mVp-p.

Overvoltage threshold 25.2–32.4 V. Overvoltage action Output voltage shuts off and is clamped by a zener diode. Protection thresholds are not additional continuous-output or peak-power ratings. Cooling, Derating and Environment Cooling Free-air convection; the ambient derating graph is for horizontal mounting. Operating temperature −30 to +85°C, subject to all applicable derating curves. Temperature/load limits The 100 VAC curve permits full load through 50°C, then 75% at 60°C, 50% at 70°C, 33% at 80°C and 25% at 85°C. The shaded −30 to −25°C region is for 230 VAC input only. Input/load limits At 60 Hz: 80% load at 85 VAC, increasing to 100% at 100 VAC; 100% from 100 to 305 VAC. Working humidity 20–90% RH, non-condensing. Storage −40 to +85°C; 10–95% RH.

  MEAN WELL IRM-15 series: PCB-Mount AC/DC Power Module - IRM-15-5

  MEAN WELL IRM-15-5 is a silicone-potted PCB-mount industrial AC/DC power module rated at 5 V, 3 A and 15 W. It accepts 85–305 VAC or 120–430 VDC and uses free-air convection. Follow the model-specific load, temperature and installation limits below. Product Datasheet Download MEAN WELL IRM-15 Datasheet (PDF) The IRM-15 section is on PDF pages 19, 20, 21. Refer to the complete mechanical drawings and notes when planning installation. Model and Construction Complete model IRM-15-5; PCB-mount AC/DC industrial power module. The final model-code field specifies the nominal DC output voltage. Construction 94V-0 flame-retardant plastic case with silicone potting. The catalogue describes basic resistance to dust and moisture; no IP rating is specified. Electrical class Class II design with no functional-ground (FG) pin. Limited power source The family feature page states that the series passes LPS. Typical applications Industrial electrical and mechanical equipment, factory automation and hand-held electronic devices. Model-Specific DC Output DC voltage 5 V. Rated current 3 A. Current range 0–3 A. Rated output power 15 W. Ripple and noise, maximum 200 mVp-p. Voltage tolerance ±2.5%; includes set-up tolerance, line regulation and load regulation. Line regulation ±0.5%. Load regulation ±1%. Efficiency, typical 78%. Ripple and noise are measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Use the continuous voltage, current and power ratings together; protection thresholds are not output-power allowances. Input and Start-Up AC input 85–305 VAC; observe the low-input derating curve. DC input 120–430 VDC. Frequency 47–440 Hz. AC current, typical 0.35 A at 115 VAC; 0.2 A at 230 VAC; 0.17 A at 277 VAC. Cold-start inrush, typical 20 A at 115 VAC; 40 A at 230 VAC. Leakage current Less than 0.25 mA at 277 VAC. No-load consumption Less than 0.1 W. Set-up and rise time 1000 ms set-up; 20 ms rise at full load. Both 230 VAC and 115 VAC are listed. Hold-up time, typical 40 ms at 230 VAC; 10 ms at 115 VAC, at full load. Switching frequency reference 65 kHz in the block diagram. Unless otherwise specified, catalogue parameters are measured at 230 VAC input, rated load and 25°C ambient. Protection Short circuit and overload Overload range: 115–190% of rated output power. Hiccup mode recovers automatically after the fault is removed; short-circuit protection is listed. Overvoltage threshold 5.75–6.75 V. Overvoltage response Output voltage shuts off and is clamped by a zener diode. Cooling, Derating and Environment Cooling Free-air convection; published temperature/load curves use horizontal mounting. Working ambient −30 to +85°C, with load derating. Temperature/load anchors -30°C: 100%; 50°C: 100%; 60°C: 75%; 70°C: 50%; 80°C: 20%; 85°C: 5%. Input-voltage/load anchors At 60 Hz: 85 VAC gives 80% load; 115 VAC gives 100%; the 100% plateau extends to 305 VAC. Operating humidity 20–90% RH, non-condensing. Storage conditions −40 to +85°C; 10–95% RH. Temperature coefficient ±0.03%/°C over 0–50°C. Vibration 10–500 Hz, 5 G, 10 minutes per cycle, 60 minutes each along X, Y and Z. Operating-altitude table entry 2,000 m. Apply the separate standards-specific overvoltage-category conditions below. Altitude footnote For operation above 2,000 m where the applicable certification permits it, the catalogue specifies a 3.5°C reduction per additional 1,000 m for fanless models. This footnote does not extend a certification altitude limit. Combine the input-voltage and temperature restrictions. The +85°C endpoint is a derated operating point, not a full-load rating. Use the complete plotted curves for intermediate conditions. Mechanical Dimensions and PCB Installation Dimensions, L × W × H 52.4 × 27.2 × 24 mm. Case drawing Case No. 219A; bottom view.
