AC-DC power pack

Product catalog summary
Overview: The document provides technical specifications and features of the DRA30-24 AC/DC power module, designed for universal input voltage and high efficiency.
Features: The power module supports a universal input range of 90 to 265 VAC, offers high efficiency of 84%, includes short circuit protection, and comes with a 2-year warranty. It is certified by UL, cUL, TUV, and CE.
General Specifications: The module operates at a switching frequency of over 55 KHz, with an isolation voltage of 3,000 VAC and isolation resistance of 100M Ω. It functions within an ambient temperature range of -10 to +50℃ and can be stored between -25 to +85℃. The maximum case temperature is 65℃, and it supports up to 90% relative humidity. The module has an M.T.B.F. of 200,000 hours and uses free air convection for cooling.
Input Specifications: The input voltage range is 90 to 265 VAC with a frequency of 47 to 63 Hz. The no-load input current is 10 mA, with a maximum input voltage of 265 VAC. Inrush current is less than 16A at 115VAC and less than 32A at 230VAC.
Output Specifications: The output voltage accuracy is ±1% at Vo_nom, with line regulation of ±0.2% and load regulation of ±0.3%. Ripple and noise are capped at 50mV, and efficiency reaches up to 84%. The voltage trim range is +15% at Vo_nom, and the module derates at +50℃. It features a green LED for DC OK indication.
Control and Protection: The module includes a T2A/250VAC input fuse, operates in hiccup mode for short circuit protection, and supports an output overload of 105 to 125%. The power ready feature requires a minimum load of 700Ω.
Approvals and Standards: The module complies with UL1950, IEC60950, EN55022 for EMI, and EN55024 for EMS standards.
Physical Characteristics: The module measures 115 x 90 x 40mm and weighs 290g. It is housed in a robust plastic case with a fine ventilation grid and is designed for easy snap-on mounting onto a DIN-Rail.
Installation: The module requires normal convection for cooling, with recommended free space above and below. Connector size ranges from 0.2-2.0mm² (AWG24-14).
Pin Assignment: The module includes pins for DC OK output, positive and negative output terminals, ground, and input terminals. A potentiometer is available for Vout adjustment.
