The 145E-29-SD by Demke Electronic is a non-isolated DC\/DC step-down converter for a nominal input voltage of 48 VDC. It operates across an input voltage range of 32 to 100 VDC and delivers 29 VDC at up to 8.50 A, equivalent to 250 W of output power. Efficiency reaches up to97% at nominal input voltage and full load.<\/p>\n","protected":false},"featured_media":8030,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[81],"product_tag":[],"product_application":[111,147,97],"product_standard":[146,140,138,144,126,130,136,122,120,118,134,142],"class_list":["post-8029","product","type-product","status-publish","has-post-thumbnail","product_cat-dc-dc-abwaertswandler","first","instock","shipping-taxable","product-type-simple"],"acf":{"vin_min":32,"vin_max":100,"vin_nom":48,"vin_peak":125,"efficiency_max":97,"vout":29,"iout":8.5,"pout":250,"output_configuration":"single","em_filter":"input_output","switching_frequency":142,"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":"bto","temp_min":-40,"temp_max":85,"thermal_shutdown_temp":90,"ip_rating":"","mtbf":"","technical_features":["cc_cv","parallel","decoupling_diode","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\/145.008_DB.pdf","datasheet_en":"https:\/\/demke-electronic.com\/wp-content\/uploads\/145.008_DB_EN.pdf","drawing":"https:\/\/demke-electronic.com\/wp-content\/uploads\/145.008_TZ.pdf","safety_instructions":"https:\/\/demke-electronic.com\/wp-content\/uploads\/145.008_SI.pdf","step":"","download_base":"145.008","step_model":"size_77x52x19","pim_id":"237979000000156139","web_visible":true,"sync_status":"success","last_sync":"2026-09-01 08:08:10","successor_sku":"","alternative_skus":"","h1_de":"145E-29-SD | DC\/DC step-down converter 48 VDC to 29 VDC, 250 W","h1_en":"145E-29-SD | DC\/DC step-down converter 48 VDC to 29 VDC, 250 W"},"_links":{"self":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product\/8029","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\/8030"}],"wp:attachment":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media?parent=8029"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_brand?post=8029"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_cat?post=8029"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_tag?post=8029"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_application?post=8029"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_standard?post=8029"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
