INTRODUCTION AND SPECIFICATIONS
Specifications
06_07 LDT-5525 3
CHAPTER 1
Specifications
1 Output current and power are rated into a 1 ohm load
2 Higher output powers can be accommodated by using an external booster. Contact ILX Lightwave for further
information
3 Broadband noise (10 Hz to 10 MHz) is measured at 1 Amp output current
4 Temperature control range depends primarily on the type of thermistor and TE module used. The range can be
extended higher or lower by selecting appropriate components; see Appendix B for more details
5 Short term temperature stability is a strong function of the thermal environment of the thermistor and TE module;
room air currents in particular can easily cause fluctuations of 0.1
