LSC APS Power Distribution Wall Mount (APW)
Power distribution is one of the most critical components of any lighting system, yet most power distros on the market are little more than a bunch of circuit breakers in a box…
Power Distribution is the most critical components of any system and lighting is no exception particularly these days when almost every fixture now needs its own mains power source. However with each fixture needing power, new problems are introduced particularly during the power up sequence.=
Firstly, in-rush currents of all the power supplies and lamps starting up at the same time often causes main breakers to trip and secondly the transient currents drawn by the power supplies cause earth protection breakers to trip. To avoid these effects results in complicated power up sequences usually requiring a human sitting there switching circuits on one at a time.
The new LSC APS distribution units are a solution to this and other problems by controlling the power-on sequence of each of the individual output circuits. In its simplest form, a single command starts the sequence and then each of the 12 outputs is turned on one output at a time with a programmable time before the next circuit turns on. In this way the peak current drawn is always low and upstream breakers will not trip.
APS units can be connected together where more than 12 circuits are required and the units automatically cascade – that is, the second unit won’t commence its start up sequence until the first has finished.
But this is just the beginning – the APS is capable of the following:
- Automatic power On/Off of circuits when DMX is detected
- Combined MCB and RCD (RCBO) breakers – circuit breaker with earth leakage protection (RCD/GFI) for each circuit
- RCBO breaker also provides Neutral Disconnect function.
- Staggered power up of outputs to prevent overloading of the supply feed breakers (cascading of multiple units is also possible)
- Control via DMX512 – presence detected turns outputs on and loss of DMX turns outputs off after a preset time delay eg. 19 minutes
- Control via GPI contact closure
- Control via RDM
- Cascading startup for individual units via XLR5 cabling and/or based on unit number
- Manual override via front panel
- 10A, 13A, 16A & 20A variants
- Monitoring of input voltages (3-phase), frequency and currents;
- Programmable overvoltage and undervoltage trips to protect loads
- Voltage and current reporting via RDM
- Three phase operation
- Single phase operation possible but input current must be limited to 63A in total;
Being a power control and distribution unit, the APS is equally at home in a variety of applications including (but certainly not limited to):
- Moving Lights;
- LED fixtures;
- Video walls;
- Audio Systems;
- Stall power for Markets and Fairgrounds
The APS is also ideal for permanent installations such as schools, churches, public halls and other venues where Energy Management is a key goal. By using APS modules to power all the lighting and video system, all the LED fixtures, video screens and moving lights will automatically be powered off a few minutes after the lighting console is turned off. When the console is next turned on, the lighting and video equipment will be sequentially powered up over a few seconds, without any user intervention, a truly Green solution.
