§6. Using the Power Controller

LC2 Power Controller

The power controller is connected between the mains supply and the light source. It switches on the supply to the light source when the exposure is started, and it switches it off again when the exposure is completed (or paused).

The power controller is connected to the light integrator using a standard 2.5mm jack plug cable. Both mono and stereo cables will work.

On the rear of the power controller are two mains electricity sockets:

  • A standard C14 (“kettle”) mains socket for the incoming electrical supply
  • A standard C13 (“reverse kettle”) mains socket for the outgoing supply to the light source
C13 (left) and C14 (right) connectors 

On the front of the power controller are:

  • An override switch to allow manual switching of the light source, if this should be necessary
  • A fuse (20x5mm)
  • A red indicator light that shows when the controller has been activated by the light integrator

The power controller is rated for 5A of steady state current. This load should not be exceeded in normal use. Higher currents may damage the device and create a fire hazard. It is the installer’s responsibility to ensure that suitable electrical wiring is used in the power controller’s installation. If unsure about what is necessary, then consult a qualified electrician.

Many lighting circuits produce an extremely high current for a few milliseconds after being switched on. This is called “inrush” current. The power controller’s electronic switch is rated for 100A of inrush current.

The power controller is shipped with a 2A ‘slow blow’ fuse which is sufficient for most light sources. You can exchange this for a higher rated fuse, for example 5A.

Mains Supply (Volts AC)Steady State Current (Amps AC)Maximum Light Source Power (Watts)
240V (UK)2A480W
220V (Europe)2A440W
110V (USA)2A220W
110V (USA)5A550W

Caution: Contact with mains electricity is potentially fatal. Do not open the power controller without first disconnecting it from the mains electricity supply. Not doing this exposes you to the risk of electric shock.
