In 2005, VxI Power acquired intellectual-property rights to Morven Electronics’ complete product range, according to contemporaneous trade coverage. The reported transfer covered more than PSU designs: it included battery chargers, DC/DC converters, DC/AC inverters, and switch-mode and linear power supplies. Production was reported to move from Morven’s Glasgow operation to VxI’s Lincoln factory as Morven closed following its founders’ retirement.
What VxI acquired
Embedded.com reported that VxI Power acquired the intellectual-property rights to Morven Electronics’ complete product range—not that it bought Morven as a going concern. The products named in the report were:
- Battery chargers
- DC/DC converters
- DC/AC inverters
- Switch-mode and linear power supplies (PSUs)
Embedded.com’s 2005 acquisition report describes Morven as having manufactured the products in Glasgow since 1992. It says the company was closing as founders Peter and Janice Newland retired, and that production of the full range was to transfer to VxI’s 9,500-square-foot factory in Lincoln. Evertiq’s 1 July 2005 report independently repeats the central account of the intellectual-property acquisition and production move.
How the transition was meant to work
Peter Newland was to remain involved as a consultant on design and development. Morven sales manager Paul Brooks and other key staff were described as supporting customers during the transition. The report identifies marine, automotive, professional audio, and telecommunications as Morven’s traditional markets.
#1 Best Overall
VxI technical director Grant Ashley described the strategic rationale as broadening VxI’s standard-product range, increasing its customer base, and strengthening its position in battery management. That was the company’s stated expectation; the report does not provide a measured outcome or transaction value.
What the surviving DDH documentation shows
A VxI Power instruction sheet, issue 5 dated 12 November 2020, documents legacy Morven DDH150 and DDH300 isolated DC/DC converter families. It identifies the DDH150A-12 as an example and describes the series as converting a DC input to an isolated DC output. The figures below are manufacturer specifications in that sheet, not independent test results.
| Documented item | Manufacturer-stated details |
|---|---|
| DDH150 family | 150 W rated output; listed dimensions 155 × 170 × 65 mm |
| DDH300 family | 300 W rated output; listed dimensions 170 × 220 × 65 mm |
| Documented DDH model input ranges | Variants cover 10–19 V, 19–36 V, 36–72 V, and 72–144 V |
| DDH150A-12 example | 10–19 V input; low setting: 12 V at 12.5 A; high setting: 13.8 V at 15 A |
| Efficiency | “Over 80% at nominal input,” as stated by the manufacturer |
| Stated operating conditions | Fully rated ambient range −10°C to +45°C; IP30; indoor use or installation inside an enclosure |
The figures apply to the DDH products described in the VxI DDH instruction sheet; they should not be generalized to the rest of Morven’s former portfolio.
Installation points in the DDH instructions
The manufacturer’s sheet calls for secure mounting, at least 100 mm of clearance for airflow, appropriately sized cables, and correct polarity. It warns that reverse polarity can blow an internal fuse and advises consulting a competent electrician if there is doubt. These are instructions for the documented DDH converter series, not universal installation guidance for every product Morven made.

Does VxI still make or sell Morven products?
That is not established by the available records. Companies House listed VXI POWER LIMITED (company number 04615501) as active when its overview was accessed on 30 September 2026; the company was incorporated on 12 December 2002, and its last accounts were made up to 31 March 2026. Those company details confirm the legal entity’s recorded status, not current manufacture, stock, support, or ownership of a specific Morven model. The dated DDH instruction sheet confirms documented product information, but does not show that any model is currently available to buy.
If you are maintaining legacy equipment, match the exact model and electrical requirements—including input range, output voltage and current, and isolation—before selecting a substitute. Do not assume a generic charger, converter, inverter, or PSU is compatible because it serves the same broad purpose.
