This robust module accepts an input voltage range of 18-32V DC (nominal 24V) and provides a precisely regulated output of 5V ±1%. Its design makes it ideal for sensitive control systems where stable power supply is essential.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFunctional Highlights\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eKey features of the CMA121 include a maximum output current of 4A, delivering up to 20W of power while maintaining an energy efficiency greater than 85%. Furthermore, it ensures minimal ripple and noise levels, with less than 50mV peak-to-peak, thereby supporting reliable operation of digital control circuits.\u003c\/p\u003e\n\u003cp\u003eThe module offers 500V DC input-to-output isolation, providing enhanced electrical protection in demanding industrial environments. This isolation not only increases system safety but also prevents ground loops in distributed control architectures, which is vital for system integrity.\u003c\/p\u003e\n\u003cp\u003eThe compact design of the CMA121 allows for easy integration into motor control panels and automation cabinets. Its wide operating tolerance makes it particularly suitable for applications with unstable power sources or long cable runs.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCMA121 3DDE300401\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDC Power Supply Module\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eABB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBrand New\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.54 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e2.8 x 18.5 x 12.8 cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHS CODE:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e8537101190\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Origin:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSweden\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDCS (Distributed Control System)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStatus:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eActive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Voltage Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e18-32V DC (24V nominal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Voltage:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e5V ±1%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Output Current:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e4A (20W power)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficiency:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e\u0026gt;85%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRipple\/Noise:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e\u0026lt;50mV peak-to-peak\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput-to-Output Isolation:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e500V DC\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTypical Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe ABB CMA121 DC Power Supply Module is ideal for:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIndustrial automation systems requiring stable power supply\u003c\/li\u003e\n\u003cli\u003eMotor control panels and automation cabinets\u003c\/li\u003e\n\u003cli\u003eApplications that experience unstable power sources or long cable runs\u003c\/li\u003e\n\u003cli\u003eEnvironments with sensitive digital control circuits needing clean power\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFAQ\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the weight of the CMA121 DC Power Supply Module?\u003c\/strong\u003e\u003cbr\u003eThe CMA121 weighs 0.54 kg.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of this power supply module?\u003c\/strong\u003e\u003cbr\u003eIts dimensions are 2.8 x 18.5 x 12.8 cm.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat input voltage range does the CMA121 support?\u003c\/strong\u003e\u003cbr\u003eIt supports an input voltage range of 18-32V DC.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the maximum output current of the CMA121?\u003c\/strong\u003e\u003cbr\u003eThe module provides a maximum output current of 4A.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHow much ripple\/noise does the CMA121 have?\u003c\/strong\u003e\u003cbr\u003eIt maintains less than 50mV peak-to-peak ripple\/noise.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53262992539958,"sku":"3DDE300401","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/2094\/8534\/files\/abb-cma121-3dde300401-dc-power-supply-module-dvn2idesb1f.jpg?v=1762918293","url":"https:\/\/www.motrolixtech.com\/products\/abb-cma121-3dde300401-dc-power-supply-module","provider":"Motrolix","version":"1.0","type":"link"}
