Welcome to 160 Rectifier.com. Knowledgebase for the 160/54/28A and 160/27/50A rectifiers.
The specification was standardised for equipment supplying DC power in a nominal 27Vdc or 54Vdc positive earth system, typically in an n+1 redundant format.
The most common rectifiers were 1,500W convection cooled (1605428A), although a limited amount of 2,000W (1605438A) products were also sold. It was common to have a shelf consisting of 2 to 6 rectifiers in parallel with a battery, essentially forming a DC UPS for backup in the event of mains failure. It was also possible to parallel shelves together to give systems of several hundred amps capability.
The 160 standard ensured that all units fitted were compatible, primarily in terms of output voltage, current, noise, regulation, basic signals, connections and physical size. There were also specifications for EMC, efficiency, harmonic distortion, power factor, electrical isolation and safety approvals.
The first manufacturer to develop rectifiers to the 160 / 164 spec was Advance Power Supplies based at Bishops Stortford in the form of the F2705X (54V o/p) and the F2705C (27V o/p). The company eventually merged with Farnell and later formed Farnell Advance and finally Advance Power. It is common to see units with all five manufacturer logos (ultimately all the same company):
The Farnell units in particular were an extremely reliable design and many units are still going strong after more than 40 years in the field.
Towards the end of 2013, a group of ex-Farnell design engineers began work on a new modern design of the 160/54/28A and 160/27/50A called the CCR1500H54V and CCR1500H27V respectively. They have proven to be extremely robust units and are highly compatible with previous generation rectifiers. They are available through Advance Product Services Ltd (www.advanceproductservices.co.uk).
The product range proved very popular and many other customers specified similar rectifiers to power their own systems. Ultimately there were a huge number of variants manufactured and (in the case of the Farnell units) these were designated by a suffix on the part number, e.g:
F2905SXE/4 (an Erskine / Microtel variant with different output voltages)
F2905SXN (a narrow version which was just 120mm wide).
F2905SCC/3 (a special variant for Shell with M6 output studs and a 29.5V nominal output voltage)
Note that none of these variants officially comply with the BT 160 specification but many can be converted back to a standard 160 with internal settings and minor component value changes.

The original design engineers for the units still exist as Advance Product Services Ltd (APS), based in Harrogate N. Yorkshire., U.K. They have a great deal of expertise with the units and can be contacted here for support including repairs, replacements and spares.
In 2014, the engineers at APS released a form, fit and function replacement for all the 160 and 164 series rectifiers called the CCR1500.
Like the unit it replaces, it is a very high quality and reliable product made in the UK with modern components and manufacturing techniques. It is fully compatible with all 160/54/28A and 160/27/50A units and can also be configured for many of the variants.
