Applications listed in the PDF

  • Observe all Cautions and Warnings both in the User Guide and on the instrument.
  • This instrument is designed to be safe to at least the following conditions: indoor use, 6500 ft (2000 m), 80% maximum relative humidity for temperatures up to 31ºC and decreasing.
  • Use the LDTC LAB instrument as specified in this guide. If not, the protection
  • The LDTC LAB instrument is intended to be used to control thermoelectrics, resistive heaters, laser diodes and other similar equipment. Please contact Wavelength Electronics for o.
  • The LDTC LAB instrument must not be operated in explosion endangered environments.
  • The equipment is not protected against liquid spills. Do not install where chemicals are used or where liquids could be spilled into the unit.

Specifications and operating details

The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.

  • If you need stable wavelength, stable temperature (better than 0.0009ºC with thermistors), stable laser diode current or power, or low noise (RMS laser driver noise as low as 3 µA), these offer the best performance and value.
  • To avoid fire hazard, use only the specified power cords with the correct grounding, voltage, and current ratings.
  • To avoid fire hazard, use only the specified fuse with the correct type number, voltage, and current ratings, and use only the recommended replacement parts.
  • The available options are 500 μA, 5 mA, and 10 mA.
  • the current limit, actual current will be ~43 mA below setpoint.
  • Stability typical for a 14 pin butterfly package laser diode with a 10 kΩ thermistor. [2] When using resistive heaters, stability can only be consistently achieved when setpoint temperatures are 10°C or more above ambient.
  • Dual Monitor Screen** within the defined tolerance, the target icon will be visible.

Engineering review checklist

  • Confirm repetitive reverse voltage, average forward current, surge current and leakage at the intended temperature.
  • Check forward-voltage loss and reverse-recovery behavior at the actual current and switching frequency.
  • Review package thermal resistance, copper area, polarity marking and transient derating before layout release.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
