It passes a 21.6–33.6V output through the V-mount connection, supporting professional equipment designed for nominal 28.8V power systems.\u003c\/p\u003e\n\n\u003cp\u003eBuilt for cinema crews using mixed battery and camera ecosystems, the KA-S21B provides a practical way to connect SWIT HB-A290B and BIVO-series batteries to suitable V-mount devices. Its thin, lightweight design minimizes unnecessary bulk on the camera while preserving access to the higher-voltage capabilities of the attached battery.\u003c\/p\u003e\n\n\u003cp\u003eThe conversion plate is particularly suited to the RED V-Raptor XL, which requires 28.8V input to activate its onboard DC output connections. When paired with a compatible B-mount battery, the adapter powers the camera across the battery’s 21.6–33.6V operating range. Connected equipment must support input voltages up to 33.6V.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eB-Mount Battery Conversion:\u003c\/strong\u003e Enables compatible V-mount cameras and devices to operate from a B-mount battery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Voltage Output:\u003c\/strong\u003e Passes a nominal 28.8V supply across a 21.6–33.6V operating range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRED V-Raptor XL Support:\u003c\/strong\u003e Provides the high-voltage input required to activate the camera’s onboard DC outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSWIT Battery Compatibility:\u003c\/strong\u003e Supports HB-A290B, BIVO-98, BIVO-160, BIVO-200, and BIVO-290 batteries.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Mounting:\u003c\/strong\u003e Combines a B-mount battery interface with a V-mount camera-side connection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThin Construction:\u003c\/strong\u003e Adds minimal depth when adapting a B-mount battery to compatible equipment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightweight Design:\u003c\/strong\u003e Reduces unnecessary weight in professional camera power configurations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e KA-S21B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e B-mount battery to V-mount conversion plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery-Side Mount:\u003c\/strong\u003e B-mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDevice-Side Mount:\u003c\/strong\u003e V-mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Input Voltage:\u003c\/strong\u003e 28.8V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Voltage Range:\u003c\/strong\u003e 21.6–33.6V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Output Voltage:\u003c\/strong\u003e 28.8V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Voltage Range:\u003c\/strong\u003e 21.6–33.6V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible SWIT Batteries:\u003c\/strong\u003e HB-A290B, BIVO-98, BIVO-160, BIVO-200, and BIVO-290\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Camera:\u003c\/strong\u003e RED V-Raptor XL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDevice Voltage Requirement:\u003c\/strong\u003e Connected V-mount equipment must support input up to 33.6V\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SWIT","offers":[{"title":"Default Title","offer_id":46579849265349,"sku":"SWIT-KAS21B","price":179.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/SWIT-KAS21B-SWITKAS21BBM_1cf76f32-df9e-4ab9-9b30-d6b0b49e9bc9.jpg?v=1784755698","url":"https:\/\/avlgear.com\/products\/swit-ka-s21b-b-mount-to-v-mount-28-8v-conversion-plate","provider":"AVLGEAR","version":"1.0","type":"link"}
