The DC\/DC converter with 27VDC or 29VDC output voltage at 22A rated current is ideally suited for 24\/7 supercapacitor operated AGVs or shuttles.The constant short-circuit current of approx. 22A and the wide input range of 19 to 70VDC give this galvanically isolated DC\/DC step-up and step-down converter ideal properties in harsh applications. Due to the polyurethane potting and the integrated cable connections, the unit has excellent climate-proof properties.Adjustments to the open-circuit voltage and thus the final charging voltage are very simple and possible at any time. We are looking forward to your enquiry!<\/p>\n","protected":false},"excerpt":{"rendered":"
The 757-27-SDB4 by Demke Electronic is a galvanically isolated DC\/DC buck-boost converter for a nominal input voltage of 48 VDC. It operates across an input voltage range of 19 to 70 VDC and delivers 27 VDC at up to 22 A, equivalent to 600 W of output power. Efficiency reaches up to95% at nominal input voltage and full load.<\/p>\n","protected":false},"featured_media":8709,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[82],"product_tag":[],"product_application":[112,111,97,110,95,109],"product_standard":[146,164,140,138,144,126,130,136,132,122,120,118,124,128,134,142],"class_list":["post-8708","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":19,"vin_max":70,"vin_nom":48,"vin_peak":75,"efficiency_max":95,"vout":27,"iout":22,"pout":600,"output_configuration":"single","em_filter":"input_output","switching_frequency":130,"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":-0.2,"switch_high_voltage_max":0.2,"mounting":"wall","connection_type":"Kabel","plug_pin_diameter":"","cable_lengths":"300 mm","produktstatus":"bto","temp_min":-40,"temp_max":85,"thermal_shutdown_temp":90,"ip_rating":"","mtbf":1100000,"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\/757.006_DB.pdf","datasheet_en":"https:\/\/demke-electronic.com\/wp-content\/uploads\/757.006_DB_EN.pdf","drawing":"https:\/\/demke-electronic.com\/wp-content\/uploads\/757.006_TZ.pdf","safety_instructions":"https:\/\/demke-electronic.com\/wp-content\/uploads\/757.006_SI.pdf","step":"","download_base":"757.006","step_model":false,"pim_id":"237979000000157855","web_visible":true,"sync_status":"success","last_sync":"2026-09-01 11:10:40","successor_sku":"","alternative_skus":"","h1_de":"757-27-SDB4 | Galvanically isolated DC\/DC buck-boost converter 48 VDC to 27 VDC, 600 W","h1_en":"757-27-SDB4 | Galvanically isolated DC\/DC buck-boost converter 48 VDC to 27 VDC, 600 W"},"_links":{"self":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product\/8708","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\/8709"}],"wp:attachment":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media?parent=8708"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_brand?post=8708"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_cat?post=8708"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_tag?post=8708"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_application?post=8708"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_standard?post=8708"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
