Thermoelectric temperature controller 3700

with LCD displayPIDambient temperature

The Model 3700 Temperature Controller provides a 336 W bipolar output for operation with thermoelectric (TE) coolers. At the unit's heart, DSP based controls allow for PID settings with fast settling times. This feature combined with sound electronics design and quality components results in great temperature stability and higher reliability. •14 A/24 V, low noise, bipolar output •Extremely stable, long term drift <0.002°C •Windows compatible user interface software and drivers •Multiple sensors supported: thermistors, RTD, AD590/592, and LM335 •Complete characterization of TE cooler (ITE and VTE) versus temperature •Automatic power management and failsafe shutdown Features 1 Hour Temperature Stability One hour temperature stability measurements performed in a typical lab environment, on a Newport laser Mount 764H-110 with an Oclaro BW-series laser running at 10W optical output power. Ambient temperature variations during the test period of the order of 2 °C is shown. The Laser mount temperature was set at 21 °C for the entire test over a 1 hour period and was held stable at 21 °C with a variation of ± 0.0004 °C over the 1 hour period. 24 Hour Temperature Stability 24 hour temperature stability measurements were performed in a typical lab environment, on a Newport Laser Mount 764H-110 with an Oclaro BW-series laser running at 10W optical output power. The graph displays ambient temperature variations during the test period of the order of 3 °C. The laser mount temperature was set to 21 °C with a variation of ± 0.00077 °C over the 24 hour period.
