What we do
Every system is designed, built and tested under one roof in Haverhill, whether it's a catalogue charger or a one-off power system for an offshore platform.
01DC power systems
Battery chargers, power supplies, rectifiers and switch-tripping units, on their own or as complete cabinet and rack systems. From 12 V to 400 V DC, standard or bespoke.
02Cathodic protection
Impressed current cathodic protection (ICCP) for pipelines, tanks, bridges, piers and reinforced concrete. Single-zone units to 120-zone systems, plus off-grid solar and wind poles for sites with no mains at all.
Why it matters
Our equipment lives in trackside cabinets, substations, pumping stations, bridge decks and offshore installations. Nobody notices it until the mains drops or a structure starts to corrode. Then it's the only thing that matters.
Our PADS-approved chargers keep the standby batteries behind signalling, point-end switching and level crossings charged and ready.
Switch-tripping chargers hold the DC supply that operates the breakers, with changeover in under 10 ms and alarms for every fault condition.
Our ICCP systems deliver exactly the current a structure needs, so corrosion stops without over-protection damaging its coatings.
Sectors
The only UK company PADS-approved to supply Network Rail with chargers and power supplies for level crossings, point-end switching, signalling and axle counters.
Rail power systemsA UVDB-approved supplier of switch-tripping chargers, control panel power and battery systems for electricity, gas and water networks.
UtilitiesCathodic protection for more than 2,000 km of pipeline, plus power systems in high IP-rated enclosures for offshore environments.
Oil & gasPlug-and-play, hot-swappable DC power for networks and data centres. In the 1990s we were the primary DC power supplier to Cable & Wireless.
TelecomsCathodic protection for bridges, piers, jetties and heritage buildings, and roadside power cabinets for Highways England.
Civil engineeringBespoke power for turbomachinery, wind turbines, PAGA systems and panic containers, in enclosures that keep out dust and condensation.
IndustrialCathodic protection
Switch-mode ICCP power built on more than 35 years of rectifier experience. Ultra-low ripple and a built-in interrupter come as standard.
How impressed current cathodic protection works
Our standard single-zone system: compact, lightweight and hot-swappable, used on its own or in parallel for higher current.
A modular system that scales to 120 independently controlled zones, made for large reinforced concrete structures.
Solar and wind hybrid power for remote sites with no mains supply, with up to eight days' autonomy without recharging.
Adds controlled power interruption to existing systems, from modern switch-mode units to older thyristor rectifiers, for accurate potential testing.
Replace routine site visits with live data. Check readings, adjust outputs and receive alarms from anywhere, and keep engineers away from roadside hazards.
Bespoke engineering
Our standard ranges cover most requirements at short lead times. When they don't, the in-house team that designs our products takes yours from first conversation to factory acceptance test, and you deal with them directly throughout.
Send your specification, drawings or simply the problem. We capture the requirements and site constraints, and visit if it helps.
Draft drawings and a specification for your review, created in SolidWorks and Altium. Nothing goes into production until you've signed it off.
Power electronics, PCBs, embedded firmware, wiring looms and enclosures, built in-house in Haverhill.
Every solution is tested in our own facility, including environmental and EMC pre-compliance testing where the application calls for it.
Witness the factory acceptance test, then we attend site for UAT. After that: spares, repairs and maintenance for the life of the system.
Test & design facilityHaverhill
We've had a successful FAT on the UPSs and our equipment. Thank you all for the effort in making this successful.
We hold high stock levels for our systems, so a failed part doesn't become weeks of downtime.
Repair and maintenance for Duvine, Rectifier Technologies and non-OEM equipment.
We can manage installation, and attend site for user acceptance testing.
Watch cathodic protection from anywhere, with automatic alarms and regular reports.
In their words
Products that work. Duvine look to meet the specification rather than just deliver what they have. Good back-up when issues arise.
Very willing to adapt the equipment to meet a fairly demanding application.
Willing to help and solve problems.
“Quick turnaround.”

Since 1981
Duvine was founded in 1981 to design and build bespoke DC power systems. Our first major projects were 12 V trackside telecoms power for British Rail and 24 V roadside systems for Highways Agency transmission stations.
Today we're part of DMS Technologies. We still design, build and test in Suffolk, and we supply the UK and the rest of the world with partners in Spain, the Netherlands and Australia.
Founded. Trackside telecoms power for British Rail and roadside power for Highways Agency transmission stations.
Modular 48 V systems for the telecoms boom. Primary DC power supplier to Cable & Wireless.
Partnership with AMV Electronica begins, covering Spain and South America. It continues today.
Safety-critical battery chargers for Network Rail level crossings and point-end switching.
Joins Rectifier Technologies. The UK team designs a new range for impressed current cathodic protection.
Acquired by DMS Technologies and renamed Duvine Limited.
Off-grid solar and wind ICCP, remote monitoring, and protection for more than 2,000 km of pipeline.

No. Our standard ranges cover most outputs from 12 V to 240 V and above at short lead times. When they don't fit, we design bespoke systems up to 400 V DC, and many projects start as a variant of a standard product.
Yes, that's most of what we do. Send your specification, drawings or simply the problem. We gather the requirements, issue draft drawings for your approval, then build and test in-house in Haverhill.
Yes. You're welcome to witness factory acceptance testing (FAT) at our Haverhill facility, and we can attend site for user acceptance testing (UAT).
Yes. We hold high stock levels of spares for our own systems and provide repair and maintenance for Duvine, Rectifier Technologies and non-OEM units.
Yes. Our ICCP systems can be monitored and controlled remotely over 4G, GSM or TCP/IP, with automatic alarms and regular performance reports by email.
Yes. The UK is our main focus, but we supply power and cathodic protection systems worldwide, with partners in Spain, the Netherlands and Australia.
Network Rail PADS approval, ISO 9001, ISO 14001, Achilles UVDB and Cyber Essentials. We're also a Gold Sustaining member of the Institute of Corrosion and a member of the Corrosion Prevention Association.
