Introduction

The XPH 75-2D is a dual output 300 watt PSU with Multi-Mode capability in a compact and attractive case.

The Multi-Mode capability enables it to operate as a dual power supply with two independent and isolated outputs, or as a single power supply of double the power. As a dual, each output provides 0 to 75V at 0 to 2A (Mode A). As a single the output can be selected as either 0 to 75V at 0 to 4A (Mode B) or 0 to 150V at 0 to 2A (Mode C). In single modes, the unused half of the unit becomes completely inoperative and its displays are blanked.

The EX series incorporates separate digital voltage and current meters on each output. The meters use bright 14mm (0.56”) LED displays and have an update rate of 4 per second providing near instantaneous response. Simultaneous metering of voltage and current provides accurate information “at a glance” and avoids any possibility of misinterpretation. When an output switch is set to “off”, the current limit setting is displayed enabling conditions to be set before the load is connected.

Excellent line and load regulation are matched by low noise and good transient response. High power efficiency ensures that the unit remains cool without any fan noise.

The XPH 75-2D has been designed to meet the stringent requirements of relevant IEC standards for safety and EMC, including harmonics emissions. All outputs are intrinsically short circuit proof, and are protected against external voltages and reverse currents.

Safety

This power supply is a Safety Class I instrument according to IEC classification and has been designed to meet the requirements of EN61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use). It is an Installation Category II instrument intended for operation from a normal single phase supply.

This instrument has been tested in accordance with EN61010-1 and has been supplied in a safe condition. This instruction manual contains some information and warnings which have to be followed by the user to ensure safe operation and to retain the instrument in a safe condition.

This instrument has been designed for indoor use in a Pollution Degree 2 environment in the temperature range 5°C to 40°C, 20% - 80% RH (non-condensing). It may occasionally be subjected to temperatures between +5°C and –10°C without degradation of its safety. Do not operate while condensation is present.

Use of this instrument in a manner not specified by these instructions may impair the safety protection provided. Do not operate the instrument outside its rated supply voltages or environmental range.

WARNING! THIS INSTRUMENT MUST BE EARTHED

Any interruption of the mains earth conductor inside or outside the instrument will make the instrument dangerous. Intentional interruption is prohibited. The protective action must not be negated by the use of an extension cord without a protective conductor.

When the instrument is connected to its supply, terminals may be live and opening the covers or removal of parts (except those to which access can be gained by hand) is likely to expose live parts. The apparatus shall be disconnected from all voltage sources before it is opened for any adjustment, replacement, maintenance or repair. Capacitors inside the power supply may still be charged even if the power supply has been disconnected from all voltage sources but will be safely discharged about 10 minutes after switching off power.

Any adjustment, maintenance and repair of the opened instrument under voltage shall be avoided as far as possible and, if inevitable, shall be carried out only by a skilled person who is aware of the hazard involved.

If the instrument is clearly defective, has been subject to mechanical damage, excessive moisture or chemical corrosion the safety protection may be impaired and the apparatus should be withdrawn from use and returned for checking and repair.

Make sure that only fuses with the required rated current and of the specified type are used for replacement. The use of makeshift fuses and the short-circuiting of fuse holders is prohibited.

Do not wet the instrument when cleaning it. The following symbols are used on the instrument and in this manual:-

Mains Operating Voltage

This instrument has a universal input range and will operate from a nominal 115V or 230V mains supply without adjustment. Check that the local supply meets the AC Input requirement given in the Specification.

Mains Lead

Connect the instrument to the AC supply using the mains lead provided. Should a mains plug be required for a different mains outlet socket, a suitably rated and approved mains lead set should be used which is fitted with the required wall plug and an IEC60320 C13 connector for the instrument end. To determine the minimum current rating of the lead-set for the intended AC supply, refer to the power rating information on the equipment or in the Specification.

Any interruption of the mains earth conductor inside or outside the instrument will make the instrument dangerous. Intentional interruption is prohibited.

Ventilation

The power supply is very efficient but nevertheless can generate significant heat at full power. The supply relies on convection cooling only and it is therefore important that ventilation is never restricted if performance and safety are to be maintained.

Installation

WARNING! THIS INSTRUMENT MUST BE EARTHED.

Connections

All connections are made from the front panel. The load should be connected to the positive (red) and negative (black) terminals marked

OUTPUT. Connect to one or both outputs as appropriate for the selected Mode, see Operation section.

Warning! Voltages above 70Vdc are hazardous live according to EN 61010-1 and great care must be taken when using the power supply at voltages above this level.

The universal safety binding posts used for the output meet the requirements for reinforced insulation for voltages up to 250Vdc because creepage and clearance to the terminal contacts is >2.5mm even with the binding post fully open. However, it is highly recommended that the binding posts are usually fully tightened and that connections are only made using leads fitted with

fixed-shroud 4mm safety plugs. Make sure that the circuit to which connections are made is appropriately insulated; no accessible parts of the external circuit should become hazardous live in normal or single fault condition as defined by EN61010-1.

Always make connections to the instrument with the OUTPUT off.

The terminal marked

is connected to the chassis and safety earth ground.

The operation of both outputs is identical in Mode A (independent mode); the following description applies to both. In Mode B and Mode C only Output 2 is active and Output 1 is disabled; the description therefore only applies to Output 2, see Mode Selection section.

Setting Up the Output

With the POWER switch on (l) and the output off the output voltage and current limit can be accurately preset using the VOLTAGE and CURRENT controls; the left-hand meter shows the set voltage and the right-hand meter shows the set maximum current.

Operation

When the the actual voltage and the right-hand meter the actual load current.

output switch is switched on, the ON lamp lights; the left-hand meter now shows

Constant Voltage

The output voltage is adjusted using the coarse and fine VOLTAGE controls; the CURRENT control sets the maximum current that can be supplied.

Constant Current

If the load resistance is low enough such that, at the output voltage set, a current greater than the current limit setting would flow, the power supply will automatically move into constant current operation. The current output is adjusted by the CURRENT control and the VOLTAGE controls set the maximum voltage that can be generated.

The CC lamp lights to show constant current mode.

Instantaneous Current Output

The current limit control can be set to limit the continuous output current to levels down to 10mA. However, in common with all precision bench power supplies, a capacitor is connected across the output to maintain stability and good transient response. This capacitor charges to the output voltage and short-circuiting of the output will produce a current pulse as the capacitor discharges which is independent of the current limit setting.

Mode Selection

The three operating modes are selected by the front panel rotary switch situated between the terminals.

Caution. Turn both outputs off before changing mode. Possible damage to the circuit being powered, and to the unit itself, may occur if the mode is switched with either output still on.

Mode A: With the switch in this position the outputs operate independently and are isolated from

one another. The voltage range on each output is 0-75V and the current range 0-2A.

Mode B: With the switch in this position only Output 2 is active; the voltage range is 0-75V and

the current range is 0-4A. The controls of Output 1 are inoperative and the display is blanked. The terminals of Output 1 are isolated from those of Output 2.

Note that with the output switch of Output 1 in the ‘ON’ position the Output lamp still lights but the terminals remain open-circuit.

Note also that the range and scaling of the current limit control doubles when changing from Mode A to Mode B, i.e. with the control set for a 1.5A limit in Mode A, the limit becomes 3A in Mode B. To avoid possible damage to the circuit being tested the outputs should be switched off before the mode is changed and the current limit set to the desired value before the output is switched on.
