Zymax International Ltd

Zymax is a UK based company specialising in the design and manufacture of quality innovative lightning and surge protection device(s) (also commonly known as SPD, TVSS).  We have devices for the protection of: AC Mains power, DC Power Supplies, Aerial/antenna and Co-Ax, Telecom PSTN, RS485, Load Cells, CCTV, FieldBus and Networks.  We can also design for your need.

Our ZM (Zymax Mains) protection range incorporate our unique MMOV (Monitored Metal Oxide Varistor). This is our trademarked and patented technology that continually monitors the actual ageing (protective state) of the ZM devices primary protectors by alerting the user by alarm or LED when the device needs or is nearing replacement.  The ZM range also alert the user to incorrect wiring (phase reversal & bad earth connection).

We can also do complete IPU (Integrated Protection Unit) solutions whereby we fit and pre-wire surge protection devices in an enclosure ready for installation - fitting glands and connectors as required.

Whatever your application we hope to be able to help you. 

Lightning & Surge Protection Devices

ZM06 (Mains 6A Power Protector & Filter)

Use the ZM06 series filter and surge protector where a clean supply is important or where there is a proven risk of surges. This unit will filter as well as surge protect the supply. Wire in series. These barriers can be easily fitted onto a convenient DIN rail, screwed directly to surface or supplied in an IPU (integrated Protection Unit) solution (Supplied in a wall mounting enclosure pre-wired complete with fused isolator)

420 Joule surge suppression with high specification 6A RFI filtering. Utilizing Zymax's patented MMOV technology giving visual and audible status indication. The ZM06 will also check its connections for live-neutral swap and earth integrity. More thorough aging (and status information) can be obtained using our ZMR reader.

Available as 230V and 110V versions.

Pre-Wired Lighnting & Surge Protection Solutions

We can do the above ZM06-2 in an enclosure with a fused isolator - a complete MMOV™ clean power solution.

Integrated Protection Unit (IPU's)

Zymax can pre-wire a complete solution in either an IP55 or IP65 enclosure as standard.  All the electrician has to do is wire the input terminals.  We can provide a pre-wired earth bus, cable glands if required, and a heavy duty M8 external earth connection.  This ensures minimal wiring and product understanding from the installation engineers.

Single Phase Lightning & Surge Protection

ZM1000 Hi-Energy AC Power Protector

High energy 1000 Joule protector for Category C applications. Ideal for fitting at mains power entry point. DIN rail protection modules incorporating our advanced MMOV monitoring technology. Providing a truly 'fit and forget' solution for major spike elimination. Can be supplied as a complete unit with fuse and IP55 enclosure (IP65 also available) or as a module to fit straight onto top hat DIN rail.

Opto coupled remote annunciation contacts and an integral surge counter** (which can be user programmed to count surges above a threshold) are standard.
**To read the surge count requires additional ZMR reader.

Available in either 230V or 110V versions.

3 Phase Lightning & Surge Protection

ZM3000 Hi-Energy 3-Phase AC Power Protector

High energy 1000 Joule protector for Category C applications. Ideal for fitting at mains power entry point. DIN rail protection modules incorporating our advanced MMOV monitoring technology. Providing a truly 'fit and forget' solution for major spike elimination. Supplied in IP55 enclosure with fuses. The 3 Replaceable ZM1000 modules can be mounted without the enclosure onto standard top hat DIN rail if desire.ZM3000 Hi-Energy 3-Phase AC Power Protector

High energy 1000 Joule protector for Category C applications. Ideal for fitting at mains power entry point. DIN rail protection modules incorporating our advanced MMOV monitoring technology. Providing a truly 'fit and forget' solution for major spike elimination. Supplied in IP55 enclosure with fuses. The 3 Replaceable ZM1000 modules can be mounted without the enclosure onto standard top hat DIN rail if desire.

PSTN Telecom line Surge Protector with BT sockets

Easy connection for protecting Phone, Fax, Modem. High energy 4 wire protection (6 wires connected). Incorporates two UK BT631 line sockets for easy connection and supplied with a 1M line connection cord. Push the button on the top panel and the LED will indicate the state of protection and the line. No power supplies or batteries are required. Standard
35mm top hat DIN rail mounting or direct to any surface using the built in tabs. Can also be supplied fitted into an enclosure complete with cable entry glands and external earth connection.

Versions also available for worldwide telecom networks with RJ11, IDC or screw terminals.

Zymax ZD and ZW data lightning and surge protection range.

The ZD200BT-4 above is part of the Zymax data protection range (ZD and ZW is a range of lightning and surge protectors for data networks.

The initial letters stand for Zymax Data and Zymax Wide bandwidth. The following numeric is the maximum voltage that is encountered on the line during normal operation. A ZD33 thus will start to clamp above 33 volts and is ideal for 4-20mA process loops that are powered from a 24 volt supply. ZD16 is suitable for RS485.

ZD devices are available with clamping voltages of 6, 16, 33, 51, 75 and 200v.

ZW available to clamp at 6, 16, 33, 51, 75 and 400 volts. ZW400 can also be used for Siemens Milltronics EnviroRanger, HydroRanger and HydroRanger plus networks.

ZA90 (Aerial Protector Lightning & Surge Suppressor)

The ZA is a range of High energy Lightning and Surge protectors for wireless coaxial and aerial/antenna cables. The initial letters stand for Zymax Aerial and the following numeric is the maximum voltage that will be encountered on the line during normal operation. A ZA90 therefore will start to clamp above 90 volts and is ideal for low power radio telemetry.
For transmitting more than 50W the ZA350 is recommended.

Available with a variety of connector terminations including BNC, N Type or TNC (50 or 75 ohm impedance). The Ni plated precision made body ensures low attenuation of signals up to several GHz. A range of mounting options is also available for this device including fitting to DIN rail, please contact us for more information.

ZT (Field Mounted Protector) Shunt Lightning & Surge Barrier

The ZT range of barriers are ideal for field-mounted transmitters and remote instrumentation, both analogue and digital. Being of a "shunt" configuration means that they can easily be retrofitted and are simply wired in parallel with any existing wiring that requires protection.

Protects 2, 3 or 4 wire transmitters from induced lightning surges and transients. Also ideal for all Field Bus Systems.

Shunt barrier for direct connection to field mounted equipment. Stainless steel enclosure.
Available in 2, 3 and 4 wire versions with 1/2" NPT, G(BSP) 1/2" and 20mm ISO thread options. ATEX certification also available.
