Three RS-422\/485 signals on terminal blocks are supported with a clamping voltage of approximately 6.8 volts. The 485HESP offers three stages of protection starting with a gas discharge tube followed by a series resistor and finally a Transient Voltage Suppresser (TVS). In order for a surge protector to work properly it is important to have a good connection to earth ground. The 485HESP offers two terminal posts and two metal mounting brackets which provide a good ground connection for the user. The 485HESP has been tested to two specifications at 6 kilovolts, IEC 1000-4-5: 1995 \"Surge Immunity Test\" and IEEE C62.41-1991 \"IEEE Recommended Practice on Surge Voltages in Low-Voltage AC Power Circuits\". To ensure the best protection of your equipment some simple connection guidelines should be followed.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e","brand":"B+B SmartWorx","offers":[{"title":"Default Title","offer_id":41078933225547,"sku":"485HESP","price":239.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1824\/0789\/files\/BB-485-HIGH-ENERGY-SURGE-PRO-WTB-485HESP.jpg?v=1748256811","url":"https:\/\/www.tecisoft.ca\/products\/b-b-485-high-energy-surge-pro-w-tb","provider":"TeciSoft","version":"1.0","type":"link"}
