Galvanically isolated buck-boost DC\/DC converter 12V, 24V, 18A with 450W power. The output voltage is 24VDC and is preset. The L-Version with its lower start-up and undervoltage lockout threshold steps up input voltages from 9VDC to 24VDC easily. The galvanically isolated DC-DC converter has been specially developed for automotive engineering and is designed for E13 approval. The output voltage can be customised in a wide range (e.g. from 12V to 90V). The U\/I characteristic can also be customised.<\/p>\n","protected":false},"excerpt":{"rendered":"
The 729L-24-SD by Demke Electronic is a galvanically isolated DC\/DC buck-boost converter for a nominal input voltage of 14 VDC. It operates across an input voltage range of 9 to 16 VDC and delivers 24 VDC at up to 18.50 A, equivalent to 450 W of output power. Efficiency reaches up to95% at nominal input voltage and full load.<\/p>\n","protected":false},"featured_media":8557,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[82],"product_tag":[],"product_application":[112,111,97],"product_standard":[146,140,138,144,126,130,136,132,122,120,118,124,128,134,142],"class_list":["post-8556","product","type-product","status-publish","has-post-thumbnail","product_cat-isolated-dc-dc-buck-boost-converters","first","instock","shipping-taxable","product-type-simple"],"acf":{"vin_min":9,"vin_max":16,"vin_nom":14,"vin_peak":18,"efficiency_max":95,"vout":24,"iout":18.5,"pout":450,"output_configuration":"single","em_filter":"input_output","switching_frequency":130,"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,"switch_high_voltage_max":0,"mounting":"wall","connection_type":"Kabel","plug_pin_diameter":"","cable_lengths":"300 mm","produktstatus":"moq","temp_min":-40,"temp_max":85,"thermal_shutdown_temp":90,"ip_rating":"","mtbf":"","technical_features":["cc_cv","parallel","no_load_short_circuit","emi_input_output","no_derating","input_low_ripple_noise","wide_input"],"remote_control":false,"isolation_type":"galv_isolated","potting":false,"certifications":["reach","rohs","ce"],"datasheet_de":"https:\/\/demke-electronic.com\/wp-content\/uploads\/729.003_DB.pdf","datasheet_en":"https:\/\/demke-electronic.com\/wp-content\/uploads\/729.003_DB_EN.pdf","drawing":"https:\/\/demke-electronic.com\/wp-content\/uploads\/729.003_TZ.pdf","safety_instructions":"https:\/\/demke-electronic.com\/wp-content\/uploads\/729.003_SI.pdf","step":"","download_base":"729.003","step_model":"size_130x130x28","pim_id":"237979000000157687","web_visible":true,"sync_status":"success","last_sync":"2026-09-01 10:11:39","successor_sku":"","alternative_skus":"","h1_de":"729L-24-SD | Galvanically isolated DC\/DC buck-boost converter 14 VDC to 24 VDC, 450 W","h1_en":"729L-24-SD | Galvanically isolated DC\/DC buck-boost converter 14 VDC to 24 VDC, 450 W"},"_links":{"self":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product\/8556","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\/8557"}],"wp:attachment":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media?parent=8556"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_brand?post=8556"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_cat?post=8556"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_tag?post=8556"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_application?post=8556"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_standard?post=8556"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
