Operating the Power Supply Locally 3

CV/CC Mode Crossover

If the power supply is in constant voltage mode and the load current increases above the current limit setting, the power supply switches to constant current mode. If the load decreases below the current limit setting, the power supply switches to constant voltage mode.

CV/CC Signal

 

 

Do not connect the CV/CC signal to a voltage source higher than 30VDC.

 

CAUTION

 

 

Always connect the CV/CC signal to the voltage source with a series resistor to

 

 

limit the sink current to less than 10mA.

 

 

 

 

 

The CV/CC signal available on the J1 connector indicates the

 

 

operating mode of the power supply. The CV/CC signal is an open

 

 

collector output with a 30V parallel zener at J1 pin 13, referenced to

 

 

common at J1 pin 12. J1 pin 12 is connected internally to the –S

 

 

terminal. When the power supply operates in constant voltage mode,

 

 

CV/CC output is open. When the power supply operates in constant

 

 

current mode, CV/CC signal output is low (0 - 0.6V), with maximum

 

 

10mA sink current.

Protection Functions

 

Over-Voltage Protection

The over-voltage protection protects against over-voltage conditions on the output. If the output voltage attempts to exceed the programmed limit in response to an analog programming signal or in the event of a power supply failure, the over-voltage protection circuit will protect the load by disabling the output. The voltage is monitored at the sense terminals, thus providing the protection level directly at the load. Upon detection of an over-voltage condition, the output is disabled, the display shows OVP, the PROT indicator blinks, and OV is set in the Questionable Condition status register.

Adjustment of the over-voltage setting can be made when the output is enabled (On) or disabled (Off). To set the OVP level, press the OVP/UVL button so that the display indicates OUP. The display will show the OVP setting. Rotate the voltage knob to adjust the OVP level. The display will show OVP and the setting value for another five seconds and then return to its previous state.

The OVP settings are limited at the minimum level to approximately 5% above the output voltage setting. Attempting to adjust the OVP below this limit will result in no response to the adjustment attempt. Refer to Appendix A for the maximum OVP settings.

Use one of the following methods to reset the OVP circuit after it activates. If the condition that caused the over-voltage shutdown is still present, the OVP circuit will turn the output off again.
