4. INSTALLATION

4.1. 19-Inch Rack Mounting

This power supply is intended for mounting on a benchtop or in a conventional 19-inch
equipment rack with optional rack adapters.

The PHV must never be installed without support in the back or sides of the unit. The PHV
should be mounted on support rails or on a suitable shelf or supports inside the rack.

4.2. Ventilation Requirements

Units rated at 350Watts and below are convection cooled, units rated at greater than
350Watts are forced air cooled. Sufficient space must be allocated so that a free flow of
cooling air can reach the back and sides of the instrument when it is in operation. Ensure
these clearances are met for adequate air flow:

 4 inches (10 cm) rear.
 1.75 inch (4.6 cm) on top and bottom.

When operating in an enclosed system, care must be taken to ensure the ambient inlet air to
the power supply does not exceed the maximum operating temperature of 40°C. This may
require addition of a system heat exchanger.

Do not operate bench top units without the feet installed. Do not expose the unit directly to
sunlight to avoid unwanted thermal effects.

4.3. Orientation

The power supply can be operated in any orientation.

4.4. AC Power Connection

Check that the input voltage rating of your PHV supply is compatible with available AC
power. For models rated at 1400W or less, the AC input power is 115VAC±10% single phase
(1P115). For models with a power rating above 1400W, the AC input power is 208VAC±10%
3 phase (3P208). The AC input rating of the unit is included in the part number label on the
rear panel. If in doubt please contact the factory.

The unit is equipped with a protective earth in the AC connector or terminal block. For
protection against electric shocks, the unit must be connected to the AC power via a
suitable 3 or 5-pole cable with a non-fused earth conductor.

83550001 Revision C

12

THE PROTECTIVE EARTH GROUND MUST BE CONNECTED

BEFORE APPLYING AC LINE POWER TO THE PHV.

For single phase models (≤1400Watt output power) AC power connectors are;

14Watts to 350Watts Models - IEC 60320-C14

700Watt models - IEC 60320-C19
For power levels greater that 700Watts, Phoenix HDFK4 terminal blocks are provided.
Use extreme caution when connecting input AC power and never apply the incorrect input

power.
An external switch or circuit breaker with the following parameters must be used as the

means of disconnection:
a) Rated voltage not less than maximum rated input voltage of the power supply.
b) Rated current not less than 150% of the power supply rated current.
c) If a circuit breaker is used it should have a C or K characteristic.
The switch or circuit breaker must be located close to the power supply and within easy

access of the operator. The switch or circuit breaker must be marked as a disconnecting
device for the equipment.

If external fuses are used they should have a higher rating than the internal fuses. Internal
fuse type/rating is shown on the Mains AC rating section of the serial number label on the
rear of the unit.

The AC input rating is marked on the rear terminal of the power supply. The rating is also
part of the unit’s model description shown in Table 1.

4.5. High Leakage Current

If the following label is located on the rear of the unit, or the unit is engraved with the text
“High Leakage Current”, it must be grounded using the ground stud with a cable of at least 6
AWG or 10mm² cross section.

83550001 Revision C

13

ONLY USE THE HV CONNECTOR AND CABLE SUPPLIED WITH
THIS INSTRUMENT. ENSURE THAT THE POWER SUPPLY IS OFF
AND DISCONNECTED FROM THE AC INPUT POWER AND THAT
ANY LOAD CAPACITORS ARE DISCHARGED AND SHORTED TO
GROUND BEFORE MAKING ANY CONNECTIONS. NEVER
HANDLE THE HV CABLE WHILE THE SUPPLY IS OPERATING.

THE HV OUTPUT CONNECTOR CAN ONLY BE OPERATED AT
RATED VOLTAGE WHEN PROPERLY MATED WITH THE UNIT.

4.6. Connecting the High Voltage Output

Before connecting the HV output cable, inspect the cable and check for signs of damage.
Always use the HV connector and cable provided with the power supply or an equivalent

substitute provided by TDK-Lambda Americas.
The shield of the HV cable or a separate conductor connected between the ground stud on

the unit and the load can be used for the return connection. The Return current must not
flow via the AC power ground! The HV cable shield is always at ground potential.

Suitable overvoltage protection and/or grounding should be used at the load return in case
the return connection to the power supply is disconnected or opened in error.

The HV return is internally connected to Ground inside the power supply via a removable
link. For most applications this connection should not be removed. If required, the Ground
link can be removed, and the HV return must be connected to Ground at the load.

In the event of load arcs or flashovers, the return connector is internally protected by a 350V
spark gap to Ground.

4.6.1. HV Output Polarity

The High Voltage output polarity should be specified at the time of ordering. Options are
Fixed Positive wrt ground, Negative wrt ground, Reversible, or Floating. The Reversible
option is only available on models rated between 3.5kV and 65kV.

Output polarity is indicated in the part number and by a Blue or Red label on the rear of the
unit. A Red label indicates Positive polarity, a Blue label indicates Negative polarity. Output
polarity is also indicated in the voltage/current displays.

Units with Reversible polarity have a combination Blue/Red label on the rear panel.

4.6.2. Floating Output

The Floating option is standard on models rated at 2kV or less, and optional for higher
voltage models.

For models rated up to 350V the outputs can float ±500V from ground.
For models rated from 650V to 2kV, the outputs can float ±2kV from ground.

4.6.3. HV Output Connector

For all PHV models rated at 650V and above, the HV output connector and 9ft cable is
supplied with the unit. For models rated less than 650V, 4mm banana plugs are used and
are widely available. Table 2 shows the output connectors used at the various available
output voltages.

HIGH VOLTAGES MAY POTENTIALLY EXIST FROM THIS POINT FORWARD.
ENSURE HV OUTPUT IS IN THE OFF POSITION BEFORE COMMENCING.

6. LOCAL OPERATION

Follow the steps below to operate the PHV supply in Local mode.

6.1. Set the Control Mode

If an optional interface is installed, ensure front panel LOCAL/REMOTE switch is depressed
and the unit is in Local Mode (Item 18 in Figure 1).

6.2. Turn on AC power

Turn ON the POWER switch (Item 11 in Figure 1). The HV output will remain OFF, and the
Local LED (Item 17 in Figure 1) illuminates, indicating local operation.

6.3. Select desired output polarity

If optional polarity reversal is installed (Item 16 in Figure 1), set the switch to the desired
position.

6.4. Set the output OVP Limit

With the OUTPUT OFF, turn the voltage potentiometer (Item 4 in Figure 1) clockwise to its
limit and push the SET VALUES switch to display set values (display flashes). Using a
screwdriver, adjust the OVP Set Point with the V-LIMIT potentiometer (Item 6 in Figure 1).
The V-LIMIT LED illuminates and the limit voltage is displayed on the VOLTAGE meter.

To operate with no output voltage limit, turn the V-LIMIT potentiometer fully clockwise. The
V-LIMIT LED will extinguish.

Once the OVP limit has been set, turn the VOLTAGE potentiometer back to the desired set
point and switch display mode to actual values by pressing SET VALUES (Item 7 in Figure

1).
Note: OVP is always active in LOCAL, REMOTE, Analog or Digital programming modes.

6.5. Set the desired output voltage/current levels

To set the output voltage/current, push the SET VALUES (Item 7 in Figure 1) button, and the
voltage/current displays will Flash and show the set points. To display the setpoint
continuously, push and hold the SET VALUES button for approximately 2 seconds.

Adjust the Voltage and Current potentiometers (Items 4/9 in Figure 1) to the desired values.
Push the SET VALUES button again to return to the actual output mode (the displays will not
flash). The potentiometers provide an adjustment range from approximately 0.1% to 100% of
the rated value.

6.6. Turning ON the output

After adjusting the SET VALUES, the output can be turned on by pushing the OUTPUT
button (Item 13 in Figure 1). The ON LED will illuminate (Item 12 in Figure 1) to show the HV
output is ON.

83550001 Revision C

24

6.7. CC/CV Mode Indication

Depending on the output voltage and current settings and the load circuit, the power supply
will operate in either constant voltage CV or constant current mode CC and the corresponding
LED (Item 3 or 8 in Figure 1) will be illuminated.

6.8. Turning the unit OFF

Turn OFF the HV output by pushing the OUTPUT button (Item 13 in Figure 1). The ON LED
will extinguish (Item 12 in Figure 1) to show the HV output is OFF.

Wait until the output voltage has reached a safe potential, then turn off the POWER switch
(Item 11 in Figure 1).

This procedure is inherently safe, because it allows the user to observe any residual load
energy discharge and verify the output voltage is at a safe level.

Turning AC POWER OFF immediately is NOT recommended, because any residual
stored energy in the output/load may remain at a dangerously high voltage for some
time, and this voltage is not displayed on the unit’s VOLTAGE meter.

7. ANALOG REMOTE CONTROL OPERATION

All remote control cabling should be as short as possible with a maximum length of 10ft
(3.3m).

To control the PHV supply using Analog remote programming, the unit must be equipped
with either the non-isolated Analog interface or the isolated Analog interface options (INA). A
unit equipped with the isolated analog interface has a label or engraving “FLOATING
ANALOG PROGRAMMING” on the rear panel. If the unit is equipped with floating return, the
isolated analog interface should be specified.

The Analog remote control interface allows the user to remotely program the output
voltage/current, turn HV ON/OFF, reverse the output polarity
and current levels. The remote interface does not allow the user to set the OVP limit, this is
only possible via the front panel as described in section 6.4.

The 15-pin D-sub analog interface connector is located on the rear panel of the supply (see
Item 4 in Figure 2). A mating connector is shipped with the unit. It is suggested that interface
connections should use shielded cable with a minimum voltage rating of 500V.

The non-isolated analog interface features ground referenced control and feedback signals.
The optional isolated interface (INA option) features up to 2kV isolation from chassis ground.

7.1. The Non-Isolated Analog Interface (ANA option)

Note that analog and digital ground (pins 6 and 9) for the external programming
signals are directly connected to HV return/0V terminal. If the HV return has been
disconnected from chassis ground by removing the internal jumper, the

programming signals can float ±300 V.
The Accuracy, Linearity, Stability and Temperature coefficient specifications are not

compromised when programming via the non-isolated analog interface.
The available remote interface signals and pin assignments are shown in Table 5 below.

Table 5. Non-Isolated Analog Interface Signals (ANA option)

7.1.1. Typical Remote Operation

Set the LOCAL/REMOTE switch (see Item 18 in Figure 2) to the REMOTE position, the
LOCAL LED will extinguish.

If the power supply also features a Digital interface option, then set the DIGITAL/ANALOG
switch (see Item 20 in Figure 2) to the ANALOG position, the ANALOG LED will illuminate.

The power supply can now be controlled via the analog interface (see Item 4 in Figure 2),
with the output voltage and current levels set by 0-10V signals, and HV ON/OFF function
by switches or relay contacts.

Some examples for operating the unit in various combinations of LOCAL and REMOTE
modes are shown in sections 7.1.2 through 7.1.4.

7.1.2. Remote HV ON/OFF with LOCAL voltage/current controls (ANA option only)

Connect a switch between Pin 12 and Pin 6 to turn HV ON/OFF (closed=ON, open=OFF).
Hard wire Pin 5 to Pin 15 and Pin 4 to Pin 8. This setup allows the HV Output to be turned
ON and OFF remotely, but the front panel potentiometers still set the output voltage and
current. This connection will only work with the non-isolated analog interface option (ANA
option).

7.1.3. HV Output is always ON, REMOTE Voltage and Current programming (ANA
option only)

Hard wire Pin 12 and 6 to turn ON the output. Connect 0-10V to Pin 8 to program the output
voltage, and 0-10V to Pin 15 to program the output current. The internal 10V reference (Pin

10) can be used with external potentiometers to generate the program signals.

7.1.4. HV Output is always ON, REMOTE Voltage programming, Current set to 100%
rated value

Hard wire Pin 12 and 6 to turn ON the output. Connect 0-10V to Pin 8 to program the output
voltage. Hard wire Pin 15 to Pin 10 to set the current to 100% of rated.

7.2. Isolated Analog Programming (INA option)

The INA option features galvanically isolated analog voltage/current programming/readback,
and digital control/readback connections. Signals are isolated using fiber optics. The
Accuracy, Linearity, Temperature coefficient and Stability specifications are limited to
±0.01% when programming via the isolated analog interface. If the unit is equipped with
floating return, the isolated analog interface should be specified.

The interface pin connections are similar to the ANA interface except the front panel
potentiometer wipers (pins 4 and 5) are not connected. Details are shown in Table 6 below.

Table 6. Isolated Analog Interface Signals (INA option)

Remote operation via the INA interface is the same as the ANA interface. Note that the
control modes described in sections 7.1.2 through 7.1.4 cannot be used.

8. DIGITAL REMOTE CONTROL OPERATION

The PHV series is available with a wide range of optional digital control interfaces. The
interface must be specified at the time of ordering. The digital interface connector is located
on the rear panel of the unit (see Figure 2 and Figure 3).

Available interfaces are;

LAN
USB
IEEE-488
RS232
RS422

Contact the factory for the availability of other digital interface options.
The digital interface allows the user to program and readback output voltage and current,

turn ON/OFF the HV output, and ramp outputs at defined rates among other functions. The
digital interface supports up to 2000 programming commands per second.

To operate the unit in Remote Digital mode, set the LOCAL/REMOTE switch (see Item 18 in
Figure 2) to the REMOTE position, the LOCAL LED will extinguish. If the power supply
also features an Analog interface option, then set the DIGITAL/ANALOG switch (see Item
20 in Figure 2) to the DIGITAL position, the DIGITAL LED will illuminate. Commands can
now be sent to the Digital interface; the BUSY LED will flash to indicate the presence of
traffic on the interface.

The remote digital interface does not allow the user to set the OVP limit, this must be done
via the front panel as described in section 6.4.

All Digital interface programming commands and setup information can be found in the
specific interface manual. Details are on our web site at www.us.tdk-lambda.com/hp.

9. PARALLEL OPERATION

Parallel operation of units with the same voltage and current ratings is possible using the
non-isolated analog interface. The interface must be installed on both units.

9.1. Parallel Master Slave operation with the Remote Analog Interface – Option 1

For basic parallel Master Slave operation, the set values for Voltage and Current on the
Master supply are used to program the output voltage and current of the Slave unit.

Connect Master Pin 4 to Slave Pin 8 for the Voltage channel, and Master Pin 5 to Slave Pin
15 for the Current channel. Hard wire Slave Pin 12 to Slave Pin 6 to turn on the HV output.
The HV output cables must be connected together at the load.

9.2. Parallel Master Slave operation with the Remote Analog Interface – Option 2

Connect the current monitor output of the Master (Pin 3) to the Current Program Input of the
Slave (Pin 15). The output voltage of the slave is set to the rated value by hard wiring the
Slave connector Pins 8 and 10 together. Hard wire Slave Pin 12 to Slave Pin 6 to turn on the
HV output. This connection ensures current sharing with parallel units. The Voltage set point
is controlled by the Master supply either in Local or Remote control as required.
