PR electronics 2240 -moduuli on korkealaatuinen ratkaisu teollisuuden virransy\u00f6tt\u00f6\u00f6n, ja se asennetaan standardiin 11-nastaiseen relekantaan. Laite sis\u00e4lt\u00e4\u00e4 kaksi-eristetyn rengassyd\u00e4nmuuntajan , jossa on erillinen 3.75 kVAC eristys prim\u00e4\u00e4ri- ja sekund\u00e4\u00e4rik\u00e4\u00e4mien v\u00e4lill\u00e4. Muuntaja on varustettu 100 \u00b0C l\u00e4mp\u00f6ylikuormitussuojalla. Vaikka datalehdess\u00e4 laite on otsikoitu hakkurivirtal\u00e4hteeksi (Switchmode power supply) , itse 2240-moduuli toimii ensisijaisesti muuntajana ja sit\u00e4 k\u00e4ytet\u00e4\u00e4n usein stabiloitujen DC-virtal\u00e4hteiden rakentamisessa. Sen avulla voidaan rakentaa luotettavia virransy\u00f6tt\u00f6j\u00e4 PELV\/SELV-sovelluksiin.<\/p>\n
