The 767UH-27.6-SD by Demke Electronic is a galvanically isolated DC\/DC buck-boost converter for a nominal input voltage of 80 VDC. It operates across an input voltage range of 30 to 110 VDC and delivers 27.60 VDC at up to 18 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":8748,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[82],"product_tag":[],"product_application":[112,111,97,110,95,109],"product_standard":[146,140,138,144,126,130,136,132,122,120,118,124,128,134,142],"class_list":["post-8740","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":30,"vin_max":110,"vin_nom":80,"vin_peak":125,"efficiency_max":95,"vout":27.6,"iout":18,"pout":500,"output_configuration":"single","em_filter":"input_output","switching_frequency":125,"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":2.5,"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\/767.004_DB.pdf","datasheet_en":"https:\/\/demke-electronic.com\/wp-content\/uploads\/767.004_DB_EN.pdf","drawing":"https:\/\/demke-electronic.com\/wp-content\/uploads\/767.004_TZ.pdf","safety_instructions":"https:\/\/demke-electronic.com\/wp-content\/uploads\/767.004_SI.pdf","step":"","download_base":"767.004","step_model":"size_130x130x28","pim_id":"237979000000157907","web_visible":true,"sync_status":"success","last_sync":"2026-09-01 11:15:04","successor_sku":"","alternative_skus":"","h1_de":"767UH-27.6-SD | Galvanically isolated DC\/DC buck-boost converter 80 VDC to 27.60 VDC, 500 W","h1_en":"767UH-27.6-SD | Galvanically isolated DC\/DC buck-boost converter 80 VDC to 27.60 VDC, 500 W"},"_links":{"self":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product\/8740","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\/8748"}],"wp:attachment":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media?parent=8740"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_brand?post=8740"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_cat?post=8740"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_tag?post=8740"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_application?post=8740"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_standard?post=8740"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
