The interface between the GR-874 connector and the printed circuit board is described in US Patent 3,426,311. | The interface between the GR-874 connector and the printed circuit board is described in US Patent 3,426,311. | ||
The 1S2 contains an internal power supply producing regulated +19 V, -19 V, and -136 V outputs. | |||
As part of this internal power supply, the 1S2 has a power transformer whose primary voltage is the 6.3 V AC | |||
provided my the 500-series mainframe on pins 13 and 14 of the plug-in interface connector. | |||
The regulators use bipolar transistors for the feedback amplifiers and the output emitter-followers. | |||
The references for the 1S2's internal power supplies are zener diodes in the 1S2. | |||
