The galvanically isolated DC\/DC buck-boost converter in the compact 2″x2″ housing is the ideal solution for applications requiring the highest technology in the smallest space. This product is specifically designed for PCB mounting and offers outstanding performance and flexibility. The “SwitchHigh” function allows for quick and easy adjustment of the output voltage from 24V to 28V, depending on application needs.<\/p>\n","protected":false},"excerpt":{"rendered":"
The 331A3-24×28-SD by Demke Electronic is a functionally isolated DC\/DC buck-boost converter for a nominal input voltage of 24 VDC. It operates across an input voltage range of 9 to 36 VDC and delivers 24 VDC at up to 1.20 A, equivalent to 30 W of output power. Efficiency reaches up to92% at nominal input voltage and full load.<\/p>\n","protected":false},"featured_media":8328,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[92],"product_tag":[],"product_application":[111,147,97,110,95,102],"product_standard":[140,122,120,118,134,142],"class_list":["post-8327","product","type-product","status-publish","has-post-thumbnail","product_cat-isolated-tht-dc-dc-converters","first","instock","shipping-taxable","product-type-simple"],"acf":{"vin_min":9,"vin_max":36,"vin_nom":24,"vin_peak":38,"efficiency_max":92,"vout":24,"iout":1.2,"pout":30,"output_configuration":"single","em_filter":"input_output","switching_frequency":225,"max_capacitive_load":"infinite","shutdown_voltage_min":-0.2,"shutdown_voltage_max":2.8,"enable_voltage_min":0,"enable_voltage_max":0,"switch_high_voltage_min":-0.2,"switch_high_voltage_max":0.2,"mounting":"pcb","connection_type":"L\u00f6tstifte","plug_pin_diameter":1,"cable_lengths":"","produktstatus":"mts","temp_min":-40,"temp_max":85,"thermal_shutdown_temp":"","ip_rating":"","mtbf":1500000,"technical_features":["cc_cv","parallel","no_load_short_circuit","emi_input_output","no_derating","input_low_ripple_noise","ultrawide_input"],"remote_control":false,"isolation_type":"functional_isolated","potting":false,"certifications":["reach","rohs"],"datasheet_de":"https:\/\/demke-electronic.com\/wp-content\/uploads\/331.007_DB.pdf","datasheet_en":"https:\/\/demke-electronic.com\/wp-content\/uploads\/331.007_DB_EN.pdf","drawing":"https:\/\/demke-electronic.com\/wp-content\/uploads\/331.007_TZ.pdf","safety_instructions":"https:\/\/demke-electronic.com\/wp-content\/uploads\/331.007_SI.pdf","step":"","download_base":"331.007","step_model":false,"pim_id":"237979000000157059","web_visible":true,"sync_status":"success","last_sync":"2026-09-10 18:53:09","successor_sku":"","alternative_skus":"","h1_de":"331A3-24x28-SD | Functionally isolated DC\/DC buck-boost converter 24 VDC to 24 VDC, 30 W","h1_en":"331A3-24x28-SD | Functionally isolated DC\/DC buck-boost converter 24 VDC to 24 VDC, 30 W"},"_links":{"self":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product\/8327","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media\/8328"}],"wp:attachment":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media?parent=8327"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_brand?post=8327"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_cat?post=8327"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_tag?post=8327"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_application?post=8327"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_standard?post=8327"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
