All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature. NOTE 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com) File Name:PS-25-SPEC 2010-10-18 25W Single Output Switching Power Supply PS-25 series Mechanical Specification Unit:mm 107 6.35 94 4-3.5 Dia Mounting Holes 1 2 3 1 CN1 2 FS1 3 AC FUSE 4 2.5A/250V CN2 To Chassis Grounding AC Input Connector (CN1) : Molex 41791-03 or equivalent DC Output Connector (CN2) : Molex 41791-04 or equivalent Pin No. Assignment Mating Housing Terminal Pin No. Assignment Mating Housing Terminal 1 AC/L 1,2 +V Molex 2139 Molex 2478 Molex 2139 Molex 2478 or equivalent or equivalent 2 No Pin 3,4 -V or equivalent or equivalent 3 AC/N Block Diagram fosc : 100KHz RECTIFIERS RECTIFIERS EMI POWER +V I/P & & FILTER SWITCHING -V FILTER FILTER PWM DETECTION CONTROL FG CIRCUIT Derating Curve Static Characteristics (24V) Ta=25 32 350 100 28 300 80 24 250 60 20 200 16 150 40 12 100 20 8 50 -10 0 10 20 30 40 50 60 (HORIZONTAL) 60 80 100 120 140 160 180 200 220 240 260 -10 45 55 (VERTICAL) AMBIENT TEMPERATURE ( ) INPUT VOLTAGE (V) 60Hz File Name:PS-25-SPEC 2010-10-18 LOAD (%) 61 2 max. 28 3.81 53 OUTPUT VOLTAGE (V) OUTPUT RIPPLE (mVp-p)
