Protection devices - Import export

Here at Knight Optical, we understand that there is no one size fits all for your optical component specifications. That is why – as well as edging down our stock optics – we also offer our entire range as custom-made components. This bespoke option is popular across a variety of sectors such as defence and aerospace, medical and research as well as engineering and manufacturing industries; to name a few. By opting for our customised service, not only will you be able to choose the material, millimetre-perfect dimensions and thicknesses best suited to your application, but you will also be able to pick appropriate optical coatings to protect or enhance your device's operability. If you would like to discuss your optical requirements with a member of our team or to find out more about our custom-made optics, please get in touch on +44 (0)1622 859444, choose option One.

• Cut-Through hole for cords & cables. • Handmade by expert craftsmen in Spain. • Made with our Signature Premium Full Grain Leather. • 100% Wool Felt. • Soft Microfibre lining. Our leather Desk Mat is perfect for keeping your desk tidy as well as protecting your devices or surfaces clean from bumps and scratches or to simply do your paper drawings comfortably on it. Our Desk Mat is handmade using rich 100% Full-Grain Leather. These are the most durable and luxurious parts of the leather and will age gracefully, oh and they’re also very soft to the touch. Additionally, can choose between a base of 100% natural wool felt, or soft microfibre. Thicker base, for extra cushioning. Perfect for any surface, specially rough or natural wooden tables. Thinner base, for extra grip. Ideal for glass tables or smooth desk surfaces. The smart and simple cable cut-through allows you to keep all cables under control.

Product Features: • The Class C - DC power series - has been designed to meet the unique requirements of protection of DC power systems found in telepower and railway applications. • Category IEC / EN / VDE: Class II / Type 2 / C. Available with and without remote signaling contacts. • DVSC 24/48 provides both common and differential mode protection using high nominal discharge rating for extended operating life under DC conditions. • DVS - A range of DIN rail mounted voltage suppressors with 24V, 48V, 110V and 240V nominal operating voltages.

Product Features: • The Class B series of over-voltage surge protective devices has been developed to protect against partial direct and indirect lighting discharges and is intended to provide protection in zones 0A - 1, per IEC 62305. • Category IEC / EN / VDE: Class I, II / Type 1, 2 / B + C. This range incorporates remote signaling contacts for central monitoring of SPD health. • DVSB275652TNS for TNS single phase networks with separate N and PE conductors. • DVSB400654TNS (65kA) for TNS three phase networks with separate N and PE conductors. • DVSB4001004TNS (100kA) for TNS three phase networks with separate N and PE conductors. • DVSB4001004TT for TT three phase networks, where N to PE galvanic isolation is required.

Product Features: • The Class C series of over-voltage surge protective devices has been developed to protect against the effects of indirect lightning discharges and induced voltages and is intended to provide protection in zones 1 2 per IEC 62305. • Category IEC / EN / VDE: Class II / Type 2 / C. Available with and without remote signaling contacts. • DVSC27545 consists of a high performance varistor block with thermal disconnection device. The plug-in module/base design facilitates replacement of a failed module in situ without the need to remove system wiring. • DVSC275452TNS Series combines two 45kA varistor modules to provide protection for single phase TNS networks. • DVSC275452TT Series combines a 45kA varistor and gas discharge tube to provide protection for TT single phase networks, where N to PE galvanic isolation is required.
