Using Over Voltage Protection (OVP)

Defining the OVP Setpoint

OVP Circuit Check

The OVP circuit protects the load in the event of a remote programming error, an incorrect voltage control adjustment, or a power supply failure. The protection circuit monitors the output voltage at the output of the power supply and will shut down the main power converter whenever a preset voltage limit is exceeded. Set the preset voltage limit (also called the setpoint or trip level) using the screwdriver-adjustable front panel OVP ADJ potentiometer, or via one of the optional GPIB or RS-232 programming interfaces.

1.Turn the power supply OFF.

2.Using a small, flat-blade screwdriver, turn the OVP ADJ potentiometer screw to a fully clockwise position.

3.Turn the power supply ON. Set the output to the desired trip voltage.

4.Slowly turn the OVP ADJ potentiometer screw counter-clockwise until the red OVP indicator lamp lights.

5.Push the power switch to OFF.

6.Turn the voltage control knob to minimum.

7.Push the power switch ON and increase the voltage to check that the power supply shuts off the output at the set voltage.

8.Reset the OVP circuit after activation by removing the overvoltage condition and turning the unit OFF and back ON, or, by momentarily activating the TTL remote shutdown circuit. See “Using the Shutdown Function” on page 39, for information about shutdown circuit operation.

1.Turn power supply ON.

2.Adjust voltage to maximum. Adjust the front panel OVP ADJUST potentiometer counter-clockwise.

3.The OVP LED will light up and the output of the power supply will drop to near zero.

4.Rotate the front panel OVP ADJUST potentiometer fully clockwise.

5.Momentarily apply 5-15 V across J210 pins 1-2 (P1 -ve, P2 +ve) or cycle the AC input power.

6.The power supply output will recover, indicating that the OVP circuit was reset by momentarily activating the TTL S/D logic or cycling the AC power.
