      Controller for Compressor or Fan Systems<\/h4>\n

      The MS27 is a compact controller for multi-stage compressor or fan systems, designed for DIN rail mounting. In addition to controlling 4 compressors via outputs OUT1 … OUT4 in combination, it is also possible to regulate an additional speed-controlled compressor for intermediate load adjustment via the PWM output. For optimised inverter control, we utilise the frequency converter’s manual potentiometer input to pre-set the inverter speed from 0 … 100%. <\/p>\n","protected":false},"featured_media":11208,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[82],"product_tag":[],"class_list":["post-11207","product","type-product","status-publish","has-post-thumbnail","product_cat-compound-controller","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product\/11207","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/comments?post=11207"}],"version-history":[{"count":1,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product\/11207\/revisions"}],"predecessor-version":[{"id":11209,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product\/11207\/revisions\/11209"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/media\/11208"}],"wp:attachment":[{"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/media?parent=11207"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product_brand?post=11207"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product_cat?post=11207"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/berndt-contec.de\/en\/wp-json\/wp\/v2\/product_tag?post=11207"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
