Teledyne 514 Instruction Manual page 23

Power for the control module is provided by a center-tapped trans-
former which takes the 115 VAC input, reduces it to 40 VAC, and feeds the
voltage to a DC power supply identical to the one installed in the detector
module. Power supply outputs are +24 VDC unregulated, and +15 VDC
regulated.
