This range of twelve-way, IEC outlet, AC mains power distribution panels with a 20 amp Powercon inlet and Powercon 'loop-out' outlet, is housed in a compact 1U rackmount case. The loop-out feature provides an un-switched, direct loop-through power outlet to supply equipment that must remain powered when the MDU is switched off, or to supply to a second MDU. All versions have on the front panel a current meter plus fuse and bi-colour LED indication of power status for each of the output channels. Switch option models have an illuminated power rocker switch. Inlet and outlets are on the rear panel.
NOTE: Current drawn from the 'loop-output' must be included in the total current calculation. Care must be taken not to exceed the maximum total load of the MDU. For switched versions, the maximum total switched load is 16 amps. loop-outlet: 20amps. For un-switched versions, the maximum total load is 20 amps, loop outlet: 20 amps.
The fuses on the front panel have adjacent bi-coloured LEDs. Green illuminated indicates that the circuit is powered correctly. Red illuminated indicates that the fuse has failed.
All outputs are numbered front and rear for easy identification and a designation- strip holder with snap-on cover is fitted on the front panel. The paper strips supplied may be inserted before or after installation; 7.5mm of printable height is available. Templates for printing designation strip labels, available as a DWG file for AutoCAD and compatible applications, can be downloaded from the appropriate product page on the Canford website.
Spare designation-strip inserts (not suitable for printers) 45-3082 and spare clear covers 45-3092 are available.
Standard (MDU19, MDU19S)
The front panel has an illuminated switch or is un-switched, independent outlet fuses with status indicators. The rear panel has a 20 amp Powercon inlet , 20 amp Powercon 'loop-out' outlet and twelve 10 amp IEC outlets. An earth stud is fitted.
Features by model
All types are available with Dawn Grey or Black front panels, and optionally with either red or green illuminated switch.
As IEC cable plugs vary enormously in size and design it is not possible to define a 'universal' connector wire retaining clip. To overcome the challenge of securing all IEC connector types both re-wireable and moulded, a single lacing-bar is fitted as standard. The stainless rods may be fitted in a variety of positions to take account of cable connector size. An additional rod may be ordered separately and fitted, which is particularly suitable where connectors of different heights are inserted or where excess cable must be doubled back. An example would be when 'double ended', fixed length, moulded AC mains cords, such as the IEC-Lock types, are used.
Mating connectors are NOT included and should be ordered separately as required.
Input connectors: Neutrik Powercon type, NAC3FCA, stock code 42-021.
Loop-out connectors: Neutrik Powercon type NAC3FCB, stock code 42-022.
Output connectors: Bulgin, stock code 42-153 or Schurter, stock code 42-054.
Moulded mains leads: A large range are offered, see AC Mains Power Leads.
Locking, moulded, mains leads: Patented, locking IEC leads, see AC Mains Power Leads - IEC-Lock or see AC Mains Power Leads - IEC-Lock+.

Switch Guard Plates
A switch guard-plate may be fitted at the time of installation or retrospectively to Canford MDUs to avoid units being accidentally switched off (or on). The central cut-out gives finger access and a clear view of the illuminated switch. Note: Different types of MDU require switch guards of different sizes, see information in descriptions.
