Page 55: Setting Output Voltage And Current Limit
Local Operation Setting Output Voltage and Current Limit Install the power supply and connect the load as described in “Installation”. Ensure that the power supply is set up for local control as described in “Shipped Configuration (Local Control Mode)” on page 3–5. Then, set the output voltage and current limit at the front panel with the following procedure. -
Page 56: Using Over Voltage Protection (Ovp)
Using Over Voltage Protection (OVP) Using Over Voltage Protection (OVP) 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. -
Page 57: Resetting The Ovp Circuit
Local Operation 7. To check that the power supply shuts off at the desired set point, slowly increase the output voltage while monitoring the front panel voltmeter. The OVP LED on the front panel turns on when the OVP circuit activates. Resetting the OVP Circuit To reset the OVP circuit after it activates: 1. -
Page 58: Using The Shutdown Function
Using the Shutdown Function Using the Shutdown Function Use the Shutdown function to disable or enable the supply’s output so that you can make adjustments to either the load or the power supply without shutting off the power supply.

Page 60: Using Multiple Supplies
Using Multiple Supplies Using Multiple Supplies WARNING There is a shock hazard at the load when using a power supply with a rated or combined output greater than 40 V. To protect personnel against accidental contact with hazardous voltages created by series connection, ensure that the load, including connections, has no live parts which are accessible. -
Page 61: Configuring Multiple Supplies For Series Operation
Local Operation Configuring Multiple Supplies for Series Operation CAUTION Do not use remote sensing during series operation. CAUTION The maximum allowable sum of the output voltages is 600 Vdc. Use series operation to obtain a single higher voltage output using two or more supplies. -
Page 62: Configuring Multiple Supplies For Parallel Operation
Using Multiple Supplies Configuring Multiple Supplies for Parallel Operation Use parallel operation to obtain a higher current through a single output using two or more supplies. Set all of the OVP setpoints to maximum. (See “Using Over Voltage Protection (OVP)” on page 3–7.) Set all of the outputs to the same voltage before connecting the positive (+) output terminals and negative (–) output terminals in parallel. -
Page 63: Sensing For Parallel Operation
Local Operation Sensing for Parallel Operation Use default local sensing to enhance power sharing between units, as the impedance of the load lines will tend to correct for current imbalance. If you use remote sensing at the load for better voltage regulation, one supply always operates in current limit mode and supplies most of the power. -
Page 64: Configuring Multiple Supplies For Split Supply Operation
Using Multiple Supplies Configuring Multiple Supplies for Split Supply Operation Split supply operation uses two power supplies to obtain two positive voltages with a common ground, or to obtain a positive-negative supply. Two Positive Voltages To obtain two positive voltages, connect the negative output terminals of both supplies together in a common connection. -
Page 65: Positive-Negative Supply
Local Operation Positive-negative Supply CAUTION To prevent possible damage to the supply, do not connect the remote program return line of the negative supply to the common connection. To obtain a positive-negative supply, connect the negative output terminal of one supply to the positive output terminal of the second supply. The positive output terminal of the first supply then provides a positive voltage relative to the common connection while the negative output terminal of the second supply provides a negative voltage. -
