Product Overview:

The HTC 4000 is a low-profile and efficient laser diode temperature controller that fits your needs. It has advanced and reliable circuitry that achieves 0.0009°C temperature stability. It has a small, low profile package that is ideal for designs with space constraints. It has a linear, PI control loop that offers maximum stability while the bipolar current source has been designed for higher efficiency.

The HTC Temperature Controllers can easily be configured for any design. Virtually any kind of temperature sensor can be used with the HTC 4000. It has a built in sensor bias current source simplifies use with resistive temperature sensors. The independently adjustable Proportional Gain (P) and Integrator Time Constant (I) can be modified to optimize laser diode temperature overshoot and stability.

The HTC 4000 has other features that offer added flexibility. A single resistor sets the maximum output current to your load. An onboard reference voltage simplifies potentiometer control of the temperature setpoint.

You can also choose to operate remotely with an external setpoint voltage. Two monitor pins provide access to the diode laser temperature setpoint voltage and the actual sensor voltage.

The HTC Series Temperature Controller is a linear controller designed for stable, low noise operation. We recommend using a regulated, linear supply for optimum performance.
