Galvanically isolated DC-DC converter for automotive applications with up to 900W output power. Galvanically isolated step-up DC-DC converter from 24 V to 110 V. The output voltage is 110 VDC and is preset. The output voltage can be customized within a wide range (e.g., from 100 V to 200 V). The U\/I characteristic curve can also be customized.<\/p>\n","protected":false},"excerpt":{"rendered":"
The 739-113-SD by Demke Electronic is a galvanically isolated DC\/DC buck-boost converter for a nominal input voltage of 24 VDC. It operates across an input voltage range of 22 to 36 VDC and delivers 113 VDC at up to 4.50 A, equivalent to 500 W of output power. Efficiency reaches up to95% at nominal input voltage and full load.<\/p>\n","protected":false},"featured_media":8601,"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-8600","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":22,"vin_max":36,"vin_nom":24,"vin_peak":38,"efficiency_max":95,"vout":113,"iout":4.5,"pout":500,"output_configuration":"single","em_filter":"input_output","switching_frequency":120,"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":"bto","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\/739.001_DB.pdf","datasheet_en":"https:\/\/demke-electronic.com\/wp-content\/uploads\/739.001_DB_EN.pdf","drawing":"https:\/\/demke-electronic.com\/wp-content\/uploads\/739.001_TZ.pdf","safety_instructions":"https:\/\/demke-electronic.com\/wp-content\/uploads\/739.001_SI.pdf","step":"","download_base":"739.001","step_model":"size_130x130x28","pim_id":"237979000000157723","web_visible":true,"sync_status":"success","last_sync":"2026-09-01 10:53:14","successor_sku":"","alternative_skus":"","h1_de":"739-113-SD | Galvanically isolated DC\/DC buck-boost converter 24 VDC to 113 VDC, 500 W","h1_en":"739-113-SD | Galvanically isolated DC\/DC buck-boost converter 24 VDC to 113 VDC, 500 W"},"_links":{"self":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product\/8600","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\/8601"}],"wp:attachment":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media?parent=8600"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_brand?post=8600"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_cat?post=8600"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_tag?post=8600"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_application?post=8600"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_standard?post=8600"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
