TTL

Shutdown

You can use the Shutdown function to disable or enable the supply's output.

Disabling the supply using TTL shutdown allows you to make adjustments to the

load or to the power supply without shutting down the power supply. With the

RS-232 interface installed, TTL shutdown is activated by a TTL signal to Pin 1 of

the J7 connector on the interface subplate. The shutdown user line uses a 0-5Vdc

TTL input with a high signal range of 2.2-5.0Vdc. The current range of the

shutdown line is 1-10mA. See Figure 2.6, “J7 User Signal Connector Circuit Block

Diagram” on page 35 for a schematic of the J7 connector containing the shutdown

user line.

You can select the logic level of the TTL input by changing the J93 connector on

the RS-232 PCB. Table2.13 shows the TTL signal levels for the J93 jumper

settings. See Figure 2.2-3 for the location of the J93 jumper on the printed circuit

board.
