This is the ultimate dc dc converter for 12VDC supply up to 12A. This ultra-compact DC-DC buck converter with very high power density has excellent thermal properties. Customer specific adjustments easily configurable. In the E-version, the optional reverse polarity protection diode is built in to prevent reverse flow of current during discharge from active loads like batteries.<\/p>\n","protected":false},"excerpt":{"rendered":"
The 145-12-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 16 to 100 VDC and delivers 12 VDC at up to 12 A, equivalent to 150 W of output power. Efficiency reaches up to95% at nominal input voltage and full load.<\/p>\n","protected":false},"featured_media":7998,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[81],"product_tag":[],"product_application":[111,147,97,95],"product_standard":[146,140,144,126,130,136,132,122,120,118,134,142],"class_list":["post-7997","product","type-product","status-publish","has-post-thumbnail","product_cat-dc-dc-abwaertswandler","first","instock","shipping-taxable","product-type-simple"],"acf":{"vin_min":16,"vin_max":100,"vin_nom":80,"vin_peak":125,"efficiency_max":95,"vout":12,"iout":12,"pout":150,"output_configuration":"single","em_filter":"input_output","switching_frequency":150,"max_capacitive_load":"infinite","shutdown_voltage_min":0,"shutdown_voltage_max":0,"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":1100000,"technical_features":["no_load_short_circuit","emi_input_output","no_derating","input_low_ripple_noise","ultrawide_input"],"remote_control":false,"isolation_type":"non_isolated","potting":false,"certifications":["reach","rohs","ce"],"datasheet_de":"https:\/\/demke-electronic.com\/wp-content\/uploads\/145.003_DB.pdf","datasheet_en":"https:\/\/demke-electronic.com\/wp-content\/uploads\/145.003_DB_EN.pdf","drawing":"https:\/\/demke-electronic.com\/wp-content\/uploads\/145.003_TZ.pdf","safety_instructions":"https:\/\/demke-electronic.com\/wp-content\/uploads\/145.003_SI.pdf","step":"","download_base":"145.003","step_model":"size_77x52x19","pim_id":"237979000000156103","web_visible":true,"sync_status":"success","last_sync":"2026-09-03 09:29:54","successor_sku":"","alternative_skus":"","h1_de":"145-12-SD | DC\/DC step-down converter 80 VDC to 12 VDC, 150 W","h1_en":"145-12-SD | DC\/DC step-down converter 80 VDC to 12 VDC, 150 W"},"_links":{"self":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product\/7997","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\/7998"}],"wp:attachment":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media?parent=7997"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_brand?post=7997"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_cat?post=7997"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_tag?post=7997"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_application?post=7997"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_standard?post=7997"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
