This range of twelve, IEC or Powercon outlet, filtered AC mains power distribution panels are housed in a compact 1U rackmount case. Loop-out feature models, provide 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 an illuminated, power rocker switch or an un-switched neon power present indicator, fuse and LED indication of power status for each of the output channels. Inlet, outlets and Earth connection are on the rear panel.
These filtered units are as the standard type with a high-performance filter, fitted internally, that helps to protect sensitive electronic components connected to the MDU against mains-borne interference and to reduce the audible effects of spikes and dips in the mains supply.
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. See tables below for individual units current rating.
The fuses on the front panel have adjacent green and red LEDs or a bi-colour LED. Green illuminated indicates that the circuit is powered correctly. Red illuminated (green off) 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.

All types are available finished in black front panels, with a green illuminated switch or ‘input power present’ neon indicator on the front panel.
Ordering Note: MDU's with red illuminated switches, red ‘input power present’ neon indicators or grey front panels are available to special order, however an MOQ may apply. Also, all fixed lead input models are available to order with custom length leads. Please contact sales for details.
A single-rod lacing-bar is fitted, which can be moved to an alternative fixing position if desired. A spare lacing bar for MDU's is available, see 42-0005.
Mating connectors are NOT included and should be ordered separately as required.

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, see CANFORD AC MAINS POWER DISTRIBUTION UNIT - Switch guards.
