SwitchPack DMX
The SwitchPack DMX is a reliable DMX controlled mains power supply for L D
luminaires, moving lights, and other inductive and capactive loads. It is available in
three versions: SwitchPack 1210 (12 channels at 10 amps), SwitchPack 1220 (12
channels at 20 amps) and SwitchPack 630 (6 channels at 32 amps), with terminal or
a selection of socket backs.
SwitchPack 1210 and 1220:
SwitchPack 630

The standard 19 inch rackmount case contains either 6 or 12 Solid State Relays for
remote switching of loads by DMX control. Solid state relays generate very little
electromagnetic interference compared to hard switched Relay contacts.
Features:
• Solid State Relays use dual SCRs (not Triacs)
• SCRs are continuous pulse train driven for no minimum load limitation
requirement
• SCRs switch On at voltage zero cross to eliminate current surges at turn-on of
capacitive loads (as caused by mechanical relay contacts)
• SCRs switch Off at current zero cross to eliminate voltage spikes at turn-off of
inductive loads (as caused by mechanical relay contacts)
• Firing angle in each half-cycle (and hence energy) always maintained equal,
and only positive and negative pairs of half-cycle energy are fed to the load
This results in a very low DC component to protect magnetic transformers
from core saturation and consequent fire hazard
• SCRs are voltage surge and spike protected
• Overload limited by thermistor (channels are switched off on long-term over-
current to limit damage due to over-heating)
• Minimum volts loss to load - only 1.5 volts
• On or Off states may be controlled by DMX remotely, or locally from the
internally lit front panel pushbuttons.
• When DMX controlled, channels turn at 60% and turn off at 40%. This
hysteresis provides flicker-free On/Off switching
• Programmable security delays to prevent switch on off of critical loads
• Manually controlled channels On/Off state always restored on power up
• DMX controlled channels always power up Off
• Keyboard disable feature to prevent unauthorised operation
• Universal power supply: 90-240vac, 50-60 hertz.

Switchpack DMX Operation
DMX Address setup
The DMX start address for each Switchpack is set by the 3 digit thumbwheel.
For example if the thumbwheel is set 001, then DMX channels 1-12 will control
SwitchPack outputs 1-12 etc. A second SwitchPack should have its DMX start
address set to 013, so its outputs follow DMX channels 13-24 etc.
Valid thumbwheel settings are 1-501 for the 12 channel version, and 1- 507 for the 6
channel version.
On/Off/DMX Mode set per channel:
Press any Key- the Channel cycles through 3 states:
1/ Channel always Off - Key L D blinks on briefly
2/ Channel always On - Key L D blinks off briefly
3/ Channel on DMX control- Key L D is either on or off (not blinking) depending the
DMX control level for that channel
The DMX levels have hysteresis levels fixed at On at 60%, and Off at 40%. The
behaviour is:
If Off, the channel is only set On if the DMX level exceeds 60%
If On, the channel is only set Off if the DMX level drops below 40%
The On time and Off response time depends on the security time settings described
below.
DMX Securit Modes (6 and 12 chn):
nhanced security delays may be chosen so that received DMX levels are averaged
over time. The longer time settings provide greater security to accidental changes in
the SwitchPack outputs:
Hold two middle centre Keys for 2 secs, then release Keys on a short flash- the fast
flashing L D shows the current DMX security setting:
L Ds 1 2 3 4 5 6
0-Full times (secs) Instant 0.15s 0.3s 0.75s 1.5s 3s
Press a new Key 1-6 to change to a new DMX security setting.

The new setting is displayed for a further 5 seconds, then after a short flash, normal
display is restored.
Note the security times above are correct for a normal DMX refresh interval
(~22msecs). These times may be longer if the DMX refresh rate sent by the control
panle does not adhere to the DMX 1990 standard.
Ke s Disable (6 and 12 chn):
Hold the two top centre Keys until you see a short flash of all mimic L Ds (about 2
secs): the keys are now disabled.
Any key press when keys are disabled gives a long error flash.
Keys Disabled state is shown by a chase up of L Ds 1-12 (1-6) every 10 secs.
Ke s Enable (6 and 12 chn):
Hold the two bottom centre Keys until you see a short flash of all mimic L Ds (about
10 secs): the keys are now enabled.
Set all Channels On/Off/DMX (12 chn only)
Hold Key 1, then press:
Key 2 - after a short flash all Channels are set Off - all Key L Ds blink on
Key 3- after a short flash all Channels are set On - all Key L Ds blink off
Key 4- after a short flash all Channels are set to DMX control - All Key L Ds are
either on or off (not blinking) depending on the DMX level
Parameter Save
5 minutes after any command change (such as Mode, DMX security, Keys
enable/disable), the new parameters are saved to flash memory. Parameter save is
shown by a chase up/down of all L Ds.
Phase A B C LEDs behaviour
L D On: correct phase power supply
L D Off: no phase power supply
L D Flashing: noisy or intermittent power supply
DMX LED behaviour
L D On: DMX ok
L D Off: no DMX connection
Intermittent Flash: noisy or intermittent DMX connection
Regular flash: DMX start address not in valid range of 1-501 (12 chn) or 1-507
(6 chn)

DMX Start Address Thumbwheel
Valid DMX start address: 12 Chn: 1-501; 6 Chn: 1-507
Invalid DMX start address: 12 Chn: 0, 502-999; 6 Chn: 0, 508-999
If an invalid address is selected the start address defaults to 1.
DMX Fail behaviour
Last DMX levels retained until power off
All DMX levels initialised to zero at power on
Temperature LED behaviour with heatsink temperature:
L D Off: under 50 degrees C
L D 2 sec Flash: between 50 and 59 degrees C
L D On between 60 and 69 degrees C
L D Rapid Flash 70 degrees C or over: all Channels are switched Off
Fan behaviour with heatsink temperature
30 degrees C: Fan starts at 50% speed
- then fan speed increases with each degree C to -
35 degrees C: Fan at 100% speed
The fan stays on for 10 minutes after the internal temperature drops below 30
degrees
SwitchPack behaviour at power on:
All L Ds set On for 1 second
Fan set On at 100% for 1 second
All Channels set Off for 1 second
SwitchPack behaviour 1 second after power on:
DMX L D shows DMX state
Phase ABC L Ds show power state
Temp L D shows temperature state
On/Off/DMX mode restored to the original settings before power off
DMX security mode restored to the original settings before power off
Keyboard enable/disable state restored to the settings before power off
Note: if power goes off before the 5 minutes timeout of Parameter Save above, the
new settings will be lost.
