INTEGRAL STIRLING CRYOCOOLER-ROTARY DRIVE 0.25W
SRI421 (0,25W@80K)
Description:
The SRI421 Integral Stirling rotary cooler is intended for use in Infrared applications, especially where low weight is needed (UAV or handheld IR cameras). New Integral rotary Stirling cryocooler model SRI421 was developed for this kind of applications with an aim of a long time (MTTF) and a small power consumption and low acoustic noise.
Rotary Motor windings are outside of the working gas. Digital electronic driver and temperature controller are on separate board and they are fully programmable via RS232 port for a customer mission profile. Over-current protection, standby mode and remote shutdown are available.
