概述：
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#176;C, providing exceptional control stability in a well designed thermal system..
这是一个双向tc-4600（热/冷），H桥控制器设计与选项设置为单向控制热电冷却/加热单元。12-36vdc控制器接收输入电压。输出电压范围可以从0到36VDC如果分裂电源使用。负载电路的脉冲宽度调制2.7KHZ提供负载0.1到25安培。该控制器的温度分辨率是0.01 # 176；C，在一个设计良好的热稳定性提供特殊的控制系统。
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 out 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.
H桥配置允许的加热和冷却之间的无缝过渡。使用电脑的RS232接口，控制器可以设置为以下任何控制配置：开/关控制，温度控制，手动控制和PID控制的任何组合。用户友好的软件无需编程经验设置控制器。RS232接口有1500伏隔离所有电子电路的干扰噪音或最小化错误信号。一旦控制器设置，计算机可能被断开，成为一个独立的单元控制器。如果计算机是左连接，它可以用于在半双工模式下的数据采集。温度也可以通过设置选择显示或通过远程电位计。PC软件还提供了多种报警类型和控制器有3个输出与5V的直流输出额定电流为25mA电流报警。在设置菜单报警功能可以设置为不报警，跟踪报警，定值报警或计算机控制报警。
