Load Wiring

Installation

Load Wiring

When connecting load wiring to the power supply, consider the following factors:

• Current carrying capacity of the wire

• Maximum load wiring length for operation with sense lines

• Noise and impedance effects of the load lines

Current Carrying Capacity

As a minimum, load wiring must have a constant capacity greater than the output current rating of the power supply. This ensures that the wiring will not be damaged even if the load is shorted. Table 2.3. shows the maximum current rating, based on 450A per square centimeter, for various gauges of wire rated for 105°C operation. Operating at the maximum current rating results in a temperature rise of approximately 30°C for a wire operating in free air. Where load wiring must operate in areas with elevated ambient temperatures or bundled with other wiring, use larger gauges or higher temperature-rated wiring. For high current applications, custom-designed bus bars are typically used. To increase the current carrying capability, use parallel cables.

Impedance

Effects

For applications using remote sensing, or for improved voltage regulation at the load, you must limit the voltage drop across each load line. We recommend that you use larger load wiring to ensure a smaller voltage drop (1V maximum under full load conditions), although units will compensate for up to 5V drop in each line with the remote sense lines connected. The combined voltage drop across the load lines and load cannot exceed the rated output of the supply.

To minimize noise pickup or radiation, use the shortest possible length of shielded-twisted pair wiring for load lines. Connect the shield to the chassis via a rear panel mounting screw. Where shielding is not possible or is impractical, twisting the wires together offers some noise immunity. When using local sense connections, use the largest practical wire size to minimize the effects of load line impedance on the regulation of the supply.

40 Operating Manual for XPR Series Power Supply

Load Connections

WARNING

Exercise caution when operating the power supply. High energy levels can be stored at the output terminals on a power supply in normal operation. In addition, potentially lethal voltages exist in the power circuit and on the output and sense connectors of a power supply with a rated output greater than 40V. Filter capacitors store potentially dangerous energy for some time after power is removed.

CAUTION

When making connections to the bus bars, ensure that each terminal’s mounting hardware and wiring assembly are placed to avoid touching the other terminal and shorting the power supply outlet. Heavy connecting cables must have some form of strain relief so they don’t loosen the connections or bend the bus bars.

Make load connections at the rear of the power supply at the positive and negative output bus bars or to the 4-terminal wire clamp connector, depending on the model. (See Figure 2.6.)

Wire Size The wire should be one size larger than necessary to accommodate the required

Load Connections

Single Load To connect a single load to the DC output bus bars (5–80V outputs):

1. Ensure that the power supply is powered OFF.

2. Place a 5/16 in. (M8) bolt in the connecting hole of the negative bus bar, and fasten the negative wire or bus bar, a flatwasher, lockwasher, and a nut to the bolt.

3. Using a wrench, turn the bolt until it is secure at approximately 25 foot-pounds (34Nm).

4. Fasten the positive wire or bus bar to the positive bus, using a bolt, flatwasher, lockwasher, and nut.

5. Tighten the bolt to approximately 25 foot-pounds (34Nm).

6. Ensure that the positive and negative wires are arranged so bare wires do not come into contact with each other or the chassis.

To connect the DC output wire clamp connectors (100–600V outputs):

• Connect appropriately sized wires as described in steps 1 to 6 above, except strip

0.5 in. (13 mm) of insulation off each load wire, and clamp in the output connector by securely tightening the vertical clamp screw for each output.

Multiple

Loads

To connect multiple loads in parallel:

• Follow the “Single Load” procedure with the following exception:

• To minimize interaction between loads, bring the wiring for each load directly

back to the supply output. When each load to the power supply is wired separately, the loads will see only the precisely regulated output from the supply. If 2 loads share a single cable, the fluctuation in current to one load will cause the voltage to vary on the others. This is due to wire impedance drops.

44 Operating Manual for XPR Series Power Supply

Remote Sensing

The power supply regulates the output voltage at the output connectors in its normal configuration without remote sense lines connected.

Remote sensing lets the power supply track and regulate the output voltage at the load, and thereby compensate for the voltage drop in the load lines. The power supply will only compensate within the limitations of its voltage rating, to a maximum of 5V per load line. Remote sensing is normally only required for critical loads which cannot tolerate the slight voltage drop in the load lines caused by their resistance. Remote sensing has no effect when the power supply is operating in Constant Current mode.

Two remote sensing connectors are located on the rear panel of the power supply. See

Figure 1.3, on page 20 for location and polarity. Connect 2 wires from these ports to

the load, where the power supply cables terminate for your connection. Carefully observe the correct polarity when making the connection.

The remote sensing input is sensitive to electrical noise, so always use a shielded twisted pair, 22AWG or greater for the sense line cable. Terminate the shield to the supply chassis or the negative output of the power supply for best results.

Section 3. Operation

Overview

Once you have installed the power supply and connected both the AC input power and the load as explained in Section 2, the power supply is in its default configuration and is ready to operate in local control mode.

Section 3 begins by explaining how to power on and power off the power supply. It

then provides information about configuring the power supply, and also gives procedures for operating the supply via the front panel controls.

In addition, brief descriptions are provided of Constant Voltage and Constant Current modes. See page 49.

Power Supply Operating States

The power supply has 4 operating states:

• Power-On

• Output Shutdown

• Soft Start

• Normal Operation

Power-On This is the period between the time that AC power is applied to the supply (AC

breaker turned on) and the time that the power supply is ready for operation. During this period, the internal circuits are powering up.

Remote Control Modes

Two analog control interfaces are available. You can control the power supply remotely using 0–5V or 0–10V signals via the remote analog programming interface or via remote resistive programming interface using 0-5kΩ or 0-10kΩ adjustable resistors.

Operation

Front Panel Controls

The power supply is shipped ready to operate in local mode using the front panel knobs and function buttons.

This section describes the function buttons and control knobs that you use to operate the power supply. (Additional details about the front panel keys, control knobs, and display annunciators are provided in Section 1, “About The XPR Power Supply”.)

The next section provides details about configuring and operating the power supply.

Function

Buttons

Four function buttons are located on the front panel. Each is described below. For the purposes of simple front panel control, you should understand the function of the LCL/RMT, OUT ON/OFF, SET POINT, and OVP buttons.

1. SET POINT VOLTAGE: Lets you pre-set a setpoint before the output is enabled. To pre-set a voltage setpoint, press SET POINT, use the Voltage knob to set a value (Local Mode). The value must be between 0 V and 103% of the units rated voltage. (See page 49.)

This output can be changed while the output is OFF.

2. SET POINT CURRENT: Lets you pre-set a setpoint before enabling it. To pre-set a current setpoint, press SET POINT, use the Current knob to set a value (Local Mode). The value must be between 0 A and 103% of the units rated current. (See page 49.)

This output can be changed while the output is OFF.

3. OUT ON/OFF: This is a latch ON/OFF button that enables (OUT position) and disables (ON position) the power supply output. Normally, you should leave the power supply in its Output Off state when no load is attached or there is no need for DC output. (See “Controlling Output ON/OFF via Front Panel” on page 53.)

When the ON annunciator is illuminated, the output is enabled. When the OFF annunciator is illuminated, the output is disabled.

4. LCL/RMT: This button lets you toggle between local and remote control. If the RMT annunciator is illuminated, both voltage and current output can only be controlled via a remote voltage source or resistive programming.

5. OVP: Lets you pre-set an OVP setpoint before output is enabled. To pre-set Over Voltage Protection setpoint limit, press OVP button and turn the front panel screw until the desired OVP limit is achieved.

50 Operating Manual for XPR Series Power Supply

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. Set the preset voltage limit (also called the set point or trip level) using the screwdriver-adjustable, front panel OVP potentiometer (OVP set).

Note The default preset limit is approximately 110% of the rated output voltage.

When using OVP with remote sensing lines connected, compensate for the voltage line drop across the output return line by measuring or calculating the line drop, then adding this value to the desired OVP setpoint.
