TC-4600 Temperature Controller
PWM Temperature Control
RS-232 Comms.
Pulse Width Modulating Temperature Controller
OVERVIEW
The TC-4600 is a bi-directional (heat/cool), H-bridge controller designed to control
thermoelectric cooling/heating units with the option to set as unidirectional. The controller
accepts an input voltage of 12-36VDC. The output voltage can range from 0 to 36VDC if a
split supply is used. The load circuit is pulse width modulated at 2.7KHz and delivers a load
of 0.1 to 25 Amps. Temperature resolution for this controller is 0.01°C, providing exceptional
control stability in a well designed thermal system.
The H-bridge configuration allows for a seamless transition between heating and cooling.
Using a PC with an RS232 interface, the controller can be set for any of the following
control configurations: On/Off control, differential temperature control, manual control or any
combination of PID control. The user friendly software requires no programming experience
to set up the controller. The RS232 interface has 1500 VAC isolation from all the electronic
circuitry minimizing the interference from noise or errant signals. Once the controller is set
up, the computer may be disconnected and the controller becomes a stand alone unit. If the
computer is left connected, it can be used for data acquisition in a half duplex mode.
The temperature may also be set through the optional display or through a remote
potentiometer.The PC software also provides for several alarm types and the controller has 3
ou puts for alarms with a 5VDC output rated for 25mA of current. In the set up menu the
alarm function may be set as no alarm, tracking alarm, fixed value alarm or computer
controlled alarm. The menu also offers selections for latching and for maintaining or cutting
the power during an alarm. The alarm sensor may by the control temperature sensor or a
secondary sensor.
