Model 718
The Model 718 power supply is a highly
regulated DC power source intended for
spectroscopy and other applications. It is capable
of powering tungsten-halogen, ceramic and glowbar
infrared light sources; this supply is flexible and
extremely stable. Rated to 250W, exceptional
performance is obtained by using a transistor series
pass regulator circuit with an additional control
circuit, providing <0.05% ripple to the source in use.
An interlock feature is provided on the lamp output
and fan connectors. Power supply output can be
terminated if user defined external conditions exist,
for example, a cover safety switch or disconnected
fan cables.
Each power supply can be operated from the front
panel controls, or remotely via 0-6V analog input. A
front panel Local/Remote switch allows users to
select mode.
