1Output current and power are rated into a 1 ohm load

2Higher output powers can be accommodated by using an external booster. Contact ILX Lightwave for further information

3Broadband noise (10 Hz to 10 MHz) is measured at 1 Amp output current

4Temperature 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

5Short 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 0.1oC in an exposed mounting configuration
