TR91-176 NTC Thermistor

25 A; Single Channel; Input 12-36 VDC, Output 0-36 VDC; RS232; Board LevelThe Bi-directional or unidirectional H-bridge configuration of the 5R7-001 temperature controller creates a seamless transition between heating and cooling as it commands the thermoelectric modules. The included user friendly PC software makes it easy for the user to change control configurations through the RS232 interface which has 1500VAC isolation from the electronic circuitry, virtually eliminating interference from noise or errant signals. Once the 5R7-001 temperature controller is set-up, the computer may be disconnected and the 5R7-001 temperature controller becomes a stand alone unit or the computer can remain connected for data acquisition. The temperature may also be set through the optional display for the 5R7-001 or remote potentiometer. The load circuit is pulse width modulated at 2.7 Khz and delivers a load current of .1 to 25 Amps.
