Precision encoder adjustment provides controlled parameter changes, while OCP, OVP, output ON\/OFF control, and panel lock help maintain a more controlled test setup.\u003c\/p\u003e\n\u003cp\u003eWith front and rear output connections, standard USB connectivity, optional RS232\/RS485 communication interfaces, and a high-current 900W output capacity, the R-SPS3030S can serve as a flexible DC test power source for power module development, evaluation, verification, and repeated laboratory testing.\u003c\/p\u003e","brand":"Shenzhen Kuaiqu Electronic Co., Ltd","offers":[{"title":"AC220V(±10%) \/ R-SPS3030S-R","offer_id":47983319318705,"sku":"R-SPS3030S-R-B-220V-0928-04","price":349.99,"currency_code":"USD","in_stock":true},{"title":"AC110V(±10%) \/ R-SPS3030S-R","offer_id":47983319351473,"sku":"R-SPS3030S-R-B-110V-0928-04","price":349.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0705\/8027\/3329\/files\/DC_Test_Power_Supply_with_Memory_Presets_KUAIQU_R-SPS3030S_30V_30A_900W_for_Power_Module_Testing-01.jpg?v=1790562520","url":"https:\/\/www.kuaiquinstrument.com\/products\/dc-test-power-supply-with-memory-presets-kuaiqu-r-sps3030s-30v-30a-900w-for-power-module-testing","provider":"KUAIQU Instrument Store","version":"1.0","type":"link"}
