Technical Description
The DLD-100B is an open-frame, OEM module
designed for integration into the user‘s equipment.
The driver requires +12 to +15VDC support
power, a high voltage DC input (150VDC maxi-
mum for Option A, 60VDC maximum for Option
B), and a +5V gate signal. The amplitude of the
high voltage DC supply controls the amplitude of
the output current pulse. The output pulse width
and frequency follow the input gate’s width and
frequency.
To minimize cost, the driver is designed so that
the laser diode is floating on the voltage of the
drain of the output transistor. The diode must be
electrically isolated from earth (chassis)
ground. The cathode (-) connects to W1, and the
anode (+) connects to W2.
