DC\/DC step-down converter for 24VDC, 48VDC and 57VDC systems with CC-CV charging characteristics. This Demke converter is optimised for 48V low-voltage networks and can be supplied by 57V Li-Ion battery systems with sufficient reserves. The still very high output current or short-circuit current of 15A is designed for 12V consumer and 13.8V battery charging applications. The flat and compact design with a specific power of 1.25Watt\/gram is ideal for space-critical applications.<\/p>\n","protected":false},"excerpt":{"rendered":"
The 142E-13.8-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 16 to 70 VDC and delivers 13.80 VDC at up to 15 A, equivalent to 200 W of output power. Efficiency reaches up to96% at nominal input voltage and full load.<\/p>\n","protected":false},"featured_media":7988,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[81],"product_tag":[],"product_application":[112,111,97,110,95],"product_standard":[146,140,138,144,126,130,136,132,122,120,118,134,142],"class_list":["post-7987","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":70,"vin_nom":48,"vin_peak":75,"efficiency_max":96,"vout":13.8,"iout":15,"pout":200,"output_configuration":"single","em_filter":"input_output","switching_frequency":141,"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":1100000,"technical_features":["cc_cv","parallel","decoupling_diode","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\/142.001_DB.pdf","datasheet_en":"https:\/\/demke-electronic.com\/wp-content\/uploads\/142.001_DB_EN.pdf","drawing":"https:\/\/demke-electronic.com\/wp-content\/uploads\/142.001_TZ.pdf","safety_instructions":"https:\/\/demke-electronic.com\/wp-content\/uploads\/142.001_SI.pdf","step":"","download_base":"142.001","step_model":"size_77x52x19","pim_id":"237979000000156071","web_visible":true,"sync_status":"success","last_sync":"2026-09-01 07:53:21","successor_sku":"","alternative_skus":"","h1_de":"142E-13.8-SD | DC\/DC step-down converter 48 VDC to 13.80 VDC, 200 W","h1_en":"142E-13.8-SD | DC\/DC step-down converter 48 VDC to 13.80 VDC, 200 W"},"_links":{"self":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product\/7987","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\/7988"}],"wp:attachment":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media?parent=7987"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_brand?post=7987"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_cat?post=7987"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_tag?post=7987"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_application?post=7987"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_standard?post=7987"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
