The Newport 3150 is a high-power temperature controller delivering 350 W maximum output for precision thermal management in laser diode, thermoelectric cooler, and temperature-sensitive applications. It combines ultra-stable bipolar output with multiple control modes, multi-sensor compatibility, and integrated data acquisition to enable demanding laboratory and industrial temperature regulation.
Technical Specifications
Power Output & Electrical Performance
• Maximum output: 350 W
• Bipolar output: ±15 A, ±28 V
• Output noise: <1 mA (rms)
• Long-term drift: <0.001°C
• Adjustable current and voltage limits
• Active power management reduces dissipation and improves stability
Temperature Control
Three control modes address diverse application needs: On/Off, PID (Proportional-Integral), and manual. The proportional-integral control circuit meets stringent stabilization requirements, particularly for laser diode systems. Direct °C readout via programmable sensor calibration constants.
Sensor Support
The controller accepts thermistors (10.0 kΩ, ±0.2°C), platinum RTDs, AD590/592 ICs, and LM335 ICs. Full thermoelectric cooler characterization capability measures ITE and VTE versus temperature.
Protection & Safety
Automatic failsafe shutdown, ITE current limiting, dual temperature thresholds (high/low), sensor open detection, and TE open detection safeguard against fault conditions.
