APPENDIX F – GDC-1 24 VDC POWER SUPPLY
1.0
PRODUCT DESCRIPTION
The GDC-1 power supply converts an ac voltage input
to +24 Vdc, which can be used to power a GS-120 light
curtain (emitter and receiver) and an SRUB Controller.
It will accept a wide range of input voltages, from 88 to
264 Vac, automatically. No jumpers or voltage strapping
is necessary. The ac input is fuse-protected against
current surges or short circuits within the high-voltage
side of the unit.

Figure 72 – GDC-1 Technical Specifications
A green LED will illuminate, indicating that +24 Vdc is
present. The +24 Vdc output voltage is adjustable with
a small Philip's head screwdriver. The output voltage
should be adjusted with a calibrated meter, once all of
the loads are connected. The dimensions and terminal
markings are shown in Figure 71.
Specifications are shown in Figure 72.
