Using the Shutdown Function

Controlling Shutdown Function via J210 Connector

Use the shutdown function to disable or enable the supply’s output via a logic level signal so that you can make adjustments to either the load or the power supply without shutting off the power supply. Activate this function via remote control through the rear panel J210 Programming and Monitoring connector, using a transistor-transistor logic (TTL) or CMOS compatible signal. The input lines of the shutdown circuit are optically isolated and will withstand a highpot test potential of 500 Vac maximum to chassis.

The shutdown circuit accepts a TTL or CMOS-compatible signal to disable or enable the power supply output. Make connections for signals at the rear panel J210 connector. See “Rear Panel J210 Connector” on page 15, for more information about the J210 connector.

To activate the shutdown function:

•Connect the control signal source between J210 connector pin 2 (shutdown/positive) and pin 1 (shutdown return/negative).

Master-Slave Tracking

Note It is important to note that a Master-Slave configuration only applies to 2 positive outputs, not split supply operation.

For tracking positive and negative outputs, use the following setup:

1.Connect master return (J210 connector pin 13) to slave RTN (J210 connector pin 13).

2.Connect master Vmon (J210 connector pin 15) to slave voltage program input (J210 connector pin 14).

Note Master/slave power supplies must have the same output ratings.

As the slave is referenced to the master’s output, the noise and ripple on the slave may increase. In addition, if the master’s output decreases due to the current limit acting, the output voltage of the slave will follow. However, overcurrent of the slave supply and consequent output voltage decrease will not reflect on the master.
