The CryoTel® Generation II controller was introduced in April of 2012 to respond to the market need for additional functionality and reduced audible noise.
The Generation II controller offers the following attributes:
- Additional functionality
- Included enclosure
- Reduced audible noise
- Tunable temperature control loop
- Sinusoidal driving frequency
- A reduction in lower order harmonic vibration induced by the controller
- Isolated RS232
- External and software commanded cooler shutdown
The Generation II controller is backward compatible with Generation I, so any setups which are communicating with Sunpower’s Generation I controller will work with the new controller. Users switching from Generation I to Generation II may need to increase the DC voltage to the controller 1-2 volts to match the maximum power they attained with the Generation I controller. The mass of the Generation II controller is 490 grams.
