Daisy-Chained Output Shut-down

Analog Programming of Output Voltage and Current

In Auto-Restart mode, the power supply restores the operating settings that were saved when it was last turned off (see below). The output is either enabled or disabled according to its last setting.

Output On/Off state	UVL level
Output voltage setting	OCP setting
Output current setting	Locked/Unlocked front panel
OVP level	Start-up mode

It is possible to configure a multiple power supply system to shut down all the units when a fault condition occurs in one of the units. SW1 setup switch 5 must be in the Down position to enable the daisy- chain operation. Other switches are unaffected by this setting.

If a fault occurs in one unit, its Power Supply OK signal is set low and its display will indicate the fault. The other units shut off with their displays indicating SO. When the fault condition is cleared, all units will recover according to their Safe-Start or Auto-Restart settings.

The following figure shows three units daisy-chained - the same connection method can be used with additional units. The Shut Off and Power Supply OK signals are referenced to Chassis Common (J1 pins 2 and 3).

	In Local mode, the output voltage and current is programmed with
	the front panel VOLTAGE and CURRENT knobs or over the remote

	programmed either by an analog voltage or by resistors connected to
	the rear panel J1 connector.
	The J1 connector also provides monitoring signals for the output
	voltage and output current. The programming range and monitoring
