useful for connecting power supplies in a “Daisy-chain” (refer to Section 5.16). The SO control can also be used to reset the OVP and Fold Protection (refer to Section 5.3 and 5.5 for details).

When the unit is shut-off by a J1 signal, the VOLTAGE display will show “SO” to indicate the unit state. J1 contact 15 is the SO signal input and contacts 2 and 3, IF_COM, are the signal return (con- nected internally). Contacts 2, 3 and 15 are optically isolated from the power supply output.

The SO control logic can be selected by the rear panel SW1 Setup switch. Refer to Table 5-2 for SW1 setting and SO Control Logic.

5.9 CV/CC SIGNAL

CAUTION

To prevent possible damage to the unit, do not connect any of the

Enable/Disable inputs to the positive or negative output potential.

NOTE

Safe Start mode-If the Enable/Disable fault condition clears when units in safe start mode recovery is by pressing OUT button or by sending an ‘OUT 1’ serial command.

Auto Restart mode-The output will return back ON automatically when the Enable/Disable fault conditions clears.

CV/CC signal indicates the operating mode of the power supply, Constant Voltage or Constant Current. The CV/CC signal is an open collector output with a 30V parallel zener, at J1-13, referenced to the COM potential at J1-12 (connected internally to the negative sense potential). When the power supply operates in Constant Volt- age mode, CV/CC output is open. When the power supply operates in Constant Current mode, the CV/CC signal output is low (0-0.6), with maximum 10mA sink current.

CAUTION

Do not connect the CV/CC signal to a voltage source higher than 30VDC. Always connect the CV/CC signal to voltage source with a series resistor to limit the sink current to less than 10mA.

5.10 PS_OK SIGNAL

The PS_OK signal indicates the fault condition of the power supply. PS_OK is a TTL signal output at J1-16, ref- erenced to IF_COM at J1-2, 3 (Isolated Interface Common). When a fault condition occurs, the PS_OK level is low, with a maximum sink current of 1mA; when no fault condition occurs, the PS_OK level is high with a maxi- mum source current of 2mA. The following faults will set the PS_OK to a Fault state:
