An extremely compact DC DC converter with 19V output voltage, developed for mobile, space-saving computer and IT applications.The Demke DC-Converter 145-19-SD delivers 10A output current at 19VDC – 19.5VDC without power derating over a wide temperature range from -40\u00b0C to +85\u00b0C. The 19V dc dc converter is used as a mobile charger for laptops or notebooks in mobile warehouse management systems.<\/p>\n","protected":false},"excerpt":{"rendered":"
The 145-19-SD by Demke Electronic is a non-isolated DC\/DC step-down converter for a nominal input voltage of 80 VDC. It operates across an input voltage range of 21 to 100 VDC and delivers 19 VDC at up to 10 A, equivalent to 190 W of output power. Efficiency reaches up to97% at nominal input voltage and full load.<\/p>\n","protected":false},"featured_media":8062,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[81],"product_tag":[],"product_application":[111,147,97,109],"product_standard":[146,120,118,134,142],"class_list":["post-8061","product","type-product","status-publish","has-post-thumbnail","product_cat-dc-dc-abwaertswandler","first","instock","shipping-taxable","product-type-simple"],"acf":{"vin_min":21,"vin_max":100,"vin_nom":80,"vin_peak":125,"efficiency_max":97,"vout":19,"iout":10,"pout":190,"output_configuration":"single","em_filter":"input_output","switching_frequency":140,"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":"Steckerleiste","plug_pin_diameter":"","cable_lengths":"","produktstatus":"moq","temp_min":-40,"temp_max":85,"thermal_shutdown_temp":90,"ip_rating":"","mtbf":"","technical_features":["cc_cv","no_load_short_circuit","emi_input_output","no_derating","input_low_ripple_noise","wide_input"],"remote_control":false,"isolation_type":"non_isolated","potting":false,"certifications":["reach","rohs","ce"],"datasheet_de":"https:\/\/demke-electronic.com\/wp-content\/uploads\/145.013_DB.pdf","datasheet_en":"https:\/\/demke-electronic.com\/wp-content\/uploads\/145.013_DB_EN.pdf","drawing":"https:\/\/demke-electronic.com\/wp-content\/uploads\/145.013_TZ.pdf","safety_instructions":"https:\/\/demke-electronic.com\/wp-content\/uploads\/145.013_SI.pdf","step":"","download_base":"145.013","step_model":"size_77x52x19","pim_id":"237979000000156207","web_visible":true,"sync_status":"success","last_sync":"2026-09-01 08:11:32","successor_sku":"","alternative_skus":"","h1_de":"145-19-SD | DC\/DC step-down converter 80 VDC to 19 VDC, 190 W","h1_en":"145-19-SD | DC\/DC step-down converter 80 VDC to 19 VDC, 190 W"},"_links":{"self":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product\/8061","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\/8062"}],"wp:attachment":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media?parent=8061"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_brand?post=8061"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_cat?post=8061"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_tag?post=8061"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_application?post=8061"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_standard?post=8061"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
