The TU Series quad units with four
independent electrically isolated single phase SCR assemblies mounted on
a space saving heatsink are available in four versions. They address the
needs of simple resistive and complex loads with communications. These
units handle loads from 25A–125A per channel, up to 500Vac. They may be
used with the model 260 Diagnostic Unit
TU1450/TU1470—The TU1450
is a communicating small frame quad unit available in a 25A or 40A rating
as a time proportioned SCR for simple resistive loads. It includes front
panel LED’s and optional load current |
measurement. It is available with
analog inputs, fast cycle or single cycle firing, PLF detection, alarms,
and digital communications with automatic switch-over to analog setpoints
during communications failure. The TU1470 large frame unit is the same
as the TU1450, but extends ratings up to 125A per channel.
TU1451/TU1471—These quad
units add phase angle and fast cycle/soft-start firing options for control
of simple resistive, variable resistive, IR and inductive heating loads
to both the small and large frame TU1450/ TU1470 models |
