Product Overview:

The RHM5K-CH is a precision unipolar temperature controller that operates from a single DC supply.It can be used to achieve control at off-ambient temperatures. It uses a PID control loop to drive resistive heaters or TEC coolers.

This product is ideal for applications where temperature stability is critical and space is tight, such as heated optics (non-condensing circumstances), CCDs, preheated liquids and chamber stabilization

The RHM offers a high level of stability and can drive up to 5 A with a small footprint. On-board 12-turn trimpots control temperature setpoint, proportional gain, and output voltage limit. A single 10-pin terminal strip provides easy access to the DC supply, sensor, resistive heater, and measurement connections.

The RHM5K-CH is suited for applications where heating or cooling (not both) is required.

The jumpers can be accessed with the cover removed. The optimal sensor voltage range is 200 mV to (V+ - 2.7 V) with an absolute maximum of 7 V. Maximum Output Current is dependent on the supply voltage and the resistance of the sensor.

The RHM5K-CH operates from a single power supply. Connect a positive voltage to V+ (pin 5) and GND (pin 6). The actual temperature can be monitored on pin 2 of the output connector.
