LNF-PS_3 is a compact power supply designed for LNF’s cryogenic Low Noise Amplifiers. The drain voltage is regulated and adjustable within a wide range, and the gate voltage is automatically and continuously adjusted to give a set drain current.
Vd and Id are clearly displayed on the LCD monitor screen for easy bias control. Vg can be monitored for trouble shooting through the banana sockets on the front panel using a multimeter. Vd and Id are set by trim potentiometers on the front panel. The power supply is powered by an external desktop transformer accepting 100-250 VAC, 50- 60 Hz (included).
