The TDX Crate power supply is a standard CR80S module.
The Power Supply, as seen from fig. 5.2.2.6-1, consists
of 3 differentpower supplies namely:
- a + 5 Volt power supply
- a + 12 Volt power supply
- a - 12 Volt power supply
The +5 Volt power supply is a 20 KHz push-pull converter
operating directly on the rectified mains voltage.
The +12 Volt and -12 Volt powr supplies are fed from
a full wave rectified transformer output.
The +12 Volt power supply is regulated by a conventional
PWM (Pulse Width Modulated) bucking regulator.
The -12 Volt power supply is regulated by a buck-boost
PWM regulator.
