3.3 Input Power to Power Supply Module
12VDC power is delivered to the power supply module via a 2 way LEMO socket, P/N
EGG.2B.302.CLL. The corresponding plug connector is P/N FGG.2B.302.CLAD92 (for
normal entry version) or P/N FHG.2B.302.CLAD62 (for right angled version). The pin out of
the connector is detailed in the table below.

3.4 Power Consumption
Unit input power specification is +12VDC ± 10%, power dissipation ≤8W with the TEC
switched off. Additional inrush current (peak power) is required when the cooler power is
switched from low to high. Peak power ≤85W with total, steady state power consumption
≤65W. The power supply module requires a means of removing the heat dissipated by it,
e.g. by screwing the module to a metal surface.
3.5 Trigger IN
External synchronisation with the start of integration signal may be achieved using the
Trigger IN connector. Input impedance = 510Ω, 200pF input capacitance. Input logic levels
are:
- Logic HIGH > 2.31V
- Logic Low < 0.99V
Min. pulse width = 100ns
3.6 Trigger OUT (Exposure)
For all modes of the camera the Trigger output, Exposure SMA, will represent the integration
period of the sensor. The trigger output signal will be a TTL output pulse. The signal will
remain low (0V) and then be driven high during the integration period. The source
impedance will be equal to 50Ω.
3.7 Trigger OUT (Readout)
For all modes of the camera the Trigger output, Readout SMA, will represent the duration of
the CCD readout. The trigger output signal will be a TTL output pulse. The signal will remain
low (0V) and then be driven high during the readout period of the CCD. The source
impedance will be equal to 50Ω.
