PRODUCTS & SERVICESProductsMTL benefits from a broad based product profile; pretty much wherever electronic equipment requiresprotection, we can supply a solution. Whether protection is required for mains power, telecom/telemetry,networks, industrial process, aerial or wireless applications, we can help. Particular areas of expertiseinclude:• Process Control• Telemetry Systems• Control and Instrumentation• Network ApplicationsServicesIn addition to our comprehensive range of surge protection devices, MTL provides expert consultingservices to aid customers in the design and deployment of surge protection systems. As members ofthe MTL Group, we are able to offer local technical and sales support throughout the world. Our servicesinclude:Surges and spikes from nearby lightning strikes, arc-welders andhigh voltage cables can destroy or disrupt unprotected electronicequipment. These destructive forces enter mains power circuitswithin buildings by a variety of methods. The primary route iswhere power, often ‘dirty’ and spike-laden, actually enters thebuilding. It is at this point that surges should be stopped in orderto prevent them from propagating further. However, surges andRFI can also corrupt power supplies from within the building. Byproviding protection at the main power distribution board andthen at each piece of equipment, mains borne surges and spikesare eliminated before they can cause damage. Power Protectionis fundamental – MTL supplies that protection.ZoneMaster SeriesZoneSentinel SeriesZoneDefender SeriesMA3100 SeriesMA3350 SeriesMA05, MA10, MA15 & 30POWER PROTECTION• Technical AdviceOur highly trained application engineers will be glad to provide unbeatable technical advice andto discuss your particular system requirements.6 7• SeminarsTraining seminars are run covering various aspects relating to the protection of electronic basedsystems.

Bulkhead mounting options are available where insertion into a panelis preferable. Typical applications for the CA Series include the protection of radiotelemetry systems, mobile communications base stations and where high inducedvoltages may be present in aerial systems.Weighing System Protection - LC30• Protects load cells, weighbridges, process weighing and silos• Rugged weatherproof enclosure• Certified for use in legal metrology application• Suitable for Intrinsically Safe circuitsThe LC30 surge protection device protects load cell and weighing systeminstallations from possible malfunctions, or damage to individual strain-gaugebridges of associated electronic instrumentation etc., caused by severe overvoltagesor impulse currents on signal cabling. Fully solid state, the LC30 clamps incomingsurges immediately without causing undue leakage losses under normal conditions.Once the surge has passed, the device automatically resets to the passive state,allowing normal operations to continue.The advanced protection concept used in the LC30 also eliminates the expensiveadditional earthing systems specified by other suppliers so field installation is verysimple indeed.The LC30 device is non-voltage producing, non-energy storing ‘simple apparatus’and as such, can be used in hazardous areas with appropriate self generated systemdocumentation.The LC30 is also certified for use in legal metrology applications.SPECIALIST PROTECTION26 27Comprehensive CCTV Surge ProtectionSpecialist Antennae Protection• Narrowband Quarterwave Stub• Wideband Quarterwave Stub• Large bandwidth dc to 6GHz• 7/16 and N-Type connectorsProtection modules available for:• Analogue video signal• RS232. RS422, RS485 for Pan Tilt Zoom (PTZ)• 24V or 48V AC/DC power, 120V or 240V AC power• Video over IP/Ethernet• Video power over Ethernet (PoE)MTL offers specialist coax protection in four technologies. Narrowband quarterwavestub for single frequency application and wideband quarterwave stub for a rangeof frequencies. These quarterwave stub devices are the most compact productsavailable today with the stub incorporated in the body of the device. Replaceable gasdischarge tube devices are available for applications requiring DC continuity. Thesedevices come in a wide range of turn-on voltages from 90V to 1000V. Finally, a uniquecombination product is available for users of quarterwave stubs who also require DCcontinuity. Please consult your MTL sales representative for more information.These modules can be purchased individually for DIN rail or surface mounting. Forspecific applications, the modules can easily be configured in sets, for example athree-module set may be required for an outdoor camera (Video, PTZ and 24V ACpower). Each module provides high, 10kA minimum, levels of protection as well asvery low insertion loss to maintain excellent video quality.Surge damage to CCTV surveillance systems and video equipment is not alwaysobvious and may reduce the reliability of the installation and lead to costly systemdowntime. Monitoring stations are particularly at risk as they may be linked to alarge number of cameras, any of which may introduce surge current from nearbylightning strikes. Fitting reliable surge protection is therefore vital, can you afford totake the risk?
