Our high-performance galvanically isolated DC\/DC step-up and step-down converter converts voltages from 24V to 200V with an output of 600W. Thanks to galvanic isolation, this device offers maximum safety and prevents unwanted current flows between the input and output circuits.<\/p>\n","protected":false},"excerpt":{"rendered":"
The 739-200 by Demke Electronic is a galvanically isolated DC\/DC buck-boost converter for a nominal input voltage of 24 VDC. It operates across an input voltage range of 18 to 36 VDC and delivers 200 VDC at up to 3 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":8636,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[82],"product_tag":[],"product_application":[112,111,97],"product_standard":[146,140,138,144,126,130,136,132,122,120,118,124,128,134,142],"class_list":["post-8635","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":18,"vin_max":36,"vin_nom":24,"vin_peak":38,"efficiency_max":95,"vout":200,"iout":3,"pout":600,"output_configuration":"single","em_filter":"input_output","switching_frequency":105,"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":false,"plug_pin_diameter":"","cable_lengths":"300 mm","produktstatus":"bto","temp_min":-40,"temp_max":85,"thermal_shutdown_temp":90,"ip_rating":"","mtbf":"","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":"","datasheet_en":"","drawing":"https:\/\/demke-electronic.com\/wp-content\/uploads\/739.004_TZ.pdf","safety_instructions":"https:\/\/demke-electronic.com\/wp-content\/uploads\/739.004_SI.pdf","step":"","download_base":"739.004","step_model":"size_130x130x28","pim_id":"237979000000157763","web_visible":true,"sync_status":"success","last_sync":"2026-09-01 10:56:46","successor_sku":"","alternative_skus":"","h1_de":"739-200 | Galvanically isolated DC\/DC buck-boost converter 24 VDC to 200 VDC, 600 W","h1_en":"739-200 | Galvanically isolated DC\/DC buck-boost converter 24 VDC to 200 VDC, 600 W"},"_links":{"self":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product\/8635","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\/8636"}],"wp:attachment":[{"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/media?parent=8635"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_brand?post=8635"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_cat?post=8635"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_tag?post=8635"},{"taxonomy":"product_application","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_application?post=8635"},{"taxonomy":"product_standard","embeddable":true,"href":"https:\/\/demke-electronic.com\/en\/wp-json\/wp\/v2\/product_standard?post=8635"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
