This range of twelve-way, IEC outlet, AC mains power distribution panels with a 20 amp, unterminated, orange, fixed-lead inlet is housed in a compact 1U rackmount case. All versions have on the front panel an illuminated power rocker switch or an un-switched neon power present indicator, fuse and dual LED indication of power status for each of the output channels. Inlet and outlets are on the rear panel. Versions with sequential switch-on, with filtered inlet, and with both sequential switch-on and filtered inlet, are available.
The fuses on the front panel have adjacent green and red LEDs. Green illuminated indicates that the circuit is powered correctly. Red illuminated (and 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.
Note: Mating connectors are NOT included and should be ordered separately as required.
The front panel has an illuminated switch or un-switched neon indicator, independent outlet fuses with status indicators. The rear panel has a 20 amp, unterminated, orange, fixed-lead inlet and twelve 10 amp IEC outlets. An earth stud is fitted.
Note: Switched versions - maximum total load: 16 amps. Un-switched versions - maximum total load: 20 amps.
These are as the standard type but, in addition, to avoid overloading the supply, the outputs are sequentially switched on when power is applied. This delay is vital where a number of pieces of equipment drawing a high ‘inrush’ current, such as CRTs, power amplifiers or equipment fitted with switch-mode power supplies, are connected to a single MDU. This sequential solution may also be used to switch on equipment in an audio installation prior to the power amplifier to avoid ‘clicks’ and possible damage to loudspeakers.
Sequential Switch-on And Switch-off
Similar to the Sequential Switch-on types above, these also are based on the standard types, but have a control activating the 'start' or 'stop' sequence. The control is a latching rocker switch, but, it should be emphasised, does not switch the supply itself. When power is supplied to the MDU, an LED shows that power is present. If the control is in the 'stop' position, no power will supplied to the outputs. Changing the control to the 'start' position will cause the outputs to be switched on sequentially. Once the sequence is complete, changing the control to 'stop' will cause the outputs to be switched off sequentially in the reverse order.
These 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.
Sequential Switch-on Plus Filtered
These versions combine the features of the Sequential switch-on and Filtered types.
Sequential Switch-on And Switch-off Plus Filtered
These versions combine the features of the Sequential Switch-on and Switch-off and Filtered types.
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.
