laser power supply circuit board
Connects front-panel switches, indicators, temperature controller modules and diode-driver modules for manual control of lasers.
All resistors = 330 ohms, 1/4W except R6, R7, R12, R13 are matched (1%) 10k resistors. Version 4 circuit board has spaces for optional trim resistors to suppress zero-offset errors in laser current readings. Version 5 accepts newer rotary switches MB05L1NCGD
Diodes = 1N4148 or 1N914
Solder the Status Wire Harness and Temp. Controller harness (actually identical parts) directly to circuit board. Connection to panel meters is through 26-wire ribbon as dual-row 13 circuit socket.
