D Series features a universal power supply with power factor correction (PFC). The device can accept any mains
voltage, from 65 V to 265 V, allowing it to function worldwide in many different congurations. The PFC reduces
current peaks on the lines and reduces the requirements placed on the mains distribution system. D Series units
offer an unparalleled power factor extremely close to one.
11.4.1. Low Inrush Current
High power ampliers with inadequate inrush current limiting can draw considerable current from the mains at
turn–on, sometimes tripping a fast–acting mains breaker. The D Series, however, has very low inrush current to
prevent tripping of breakers. Several units can, under normal conditions, be powered up simultaneously. If you
do experience problems powering up multiple units simultaneously, they must either be turned on manually in an
ordered manner, or sequenced remotely using the Lake Controller software’s Global Control feature. Alternatively,
the capacity of the mains supply should be increased.
NOTE: If insufcient power is available to allow simultaneous power–up, then there is probably
insufcient capacity for full power output during operation. It is recommended that additional capacity is
added to the mains power distribution system.
11.4.2. Adaptive rail control
The D Series slimline models have Adaptive rail control available in Performance (default) and Green mode.
In Green mode, this feature further increase the slimline models green credentials by lowering the idle
consumption. This is achieved by lowering power supply’s supply voltage, to the
to allow for full power outtake, as soon as the signal returns. This feature is user controlled via the
Lake Controller, where it can be turned on or off.
