Model
5C7-195 is a bi-directional controller for Thermoelectric modules.
It has an internal power supply and full “H” bridge capable
of load currents up to four amperes. Model 5C7-195 may be used as a
heat or cool only controller with resistive heaters or TE modules
with load currents up to five amperes. Model 5C7-195 may be used in
conjunction with an external power supply as a heat only, or cool
only controller with load currents up to 10 amps.
The
controllers’ internal power supply accepts the universal AC
voltage range of 85VAC to 260VAC. Electrical isolation is maintained
between the AC power input and the DC load circuits.
The
H bridge configuration of solid state MOSFET output devices allows
for the bi-directional flow of current through the thermoelectric
modules. This controller is PC programmable via an RS232
communication port for direct interface with a compatible PC. The
RS232 communications interface has 1500 VAC isolation from all other
electronic circuitry minimizing interference from noise or errant
signals caused by common ground loops. The easily accessible
communications link permits a variety of operational mode
configurations. Field selectable parameters or data acquisition in a
half duplex mode can be performed. This controller will accept a
communications cable length in accordance with RS232 interface specifications.
Once
the desired set parameters are established the PC may be
disconnected and Model 5C7-195 becomes a stand alone controller. All
parameters settings are retained in non-volatile memory.
The
controller has a digital display of control functions. The front
panel controls may be used to adjust the set temperature, or output
voltage when the internal power supply is used, or view actual or
alarm temperature.
The
user friendly, communications software requires no prior programming
experience to establish operation. A command set is provided for
qualified personnel to program a software interface and data log information.
