PL & PL-P Series

Laboratory Power Supplies

Standard and Programmable models, 35 watts to 240 watts

Thurlby Thandar PL series

the Premier range of laboratory power supplies

Precision with convenience

The Thurlby Thandar PL series of labo-

Greater resolution and

control

The PL series sets the standard for sim-

ple and comprehensive control. Voltages

are set with coarse and fine controls for

speed with precision. Currents are set with

a semi-logarithmic control for increased

resolution at low current levels.

ratory bench power supplies has estab-

lished itself in many countries as the

“premier” range.

rent limit set point is displayed. With the

output switch “on” the actual output cur-

rent flowing is displayed.

High resolution controls enable precise

setting of voltage and current levels

whilst high accuracy digital meters pro-

vide clear, unambiguous readings.

This invaluable feature allows delicate

circuits to be protected by accurately set-

ting the current limit level (down to a few

milliamps if necessary) before connecting

the circuit under test.

All of the many features of these PSUs

have been carefully designed to give the

user not just greater precision, but

greater clarity, more control and unri-

valled ease of use.

The DC output switch enables voltage

and current levels to be set before the

load is connected.

The range has now been improved and

extended to offer even better perform-

ance and choice.

Digital accuracy and

convenience

PL series units incorporate digital meters

with a 3.75 digit scale length (4095

counts) to provide greater accuracy and

resolution than other PSUs.

Large and bright LEDs give a clear and

unambiguous reading. An update rate of

4 per second provides near instantane-

ous response.

Separate meters are used for voltage

and current, eliminating the need for me-

ter function switches with their attendant

problems of misinterpretation.

A damping switch for the current meter

simplifies measurements on rapidly vary-

ing loads.

Remote sense for

precision at high currents

PL series units incorporate integrated

band-gap reference diodes as the basis

for stabilisation of both voltage and cur-

rent.

● Simultaneous digital metering of voltage and current.

● True constant voltage or constant current operation.

● Twin 3.75 digit meters with large LED displays.

● 0.1% accuracy; 0.01 Volts and 0.001 Amps resolution.

● Excellent stability, resolution and setting accuracy.

● DC output switches, automatic mode indication.

● Precise control and monitoring of current limit settings.

● Remote sense facility for high-current precision.

● Current meter damping switch for fluctuating currents.

● Parallel and tracking modes on QMD & QMT models.

● High current “logic supply” output on QMT models.

Remote sense terminals enable the pre-

cision to be maintained at high currents

by eliminating the effects of connection

lead resistance.

Without remote sense lead resistance of

just a few tens of milliohms can seriously

degrade regulation and produce mis-

leading results. (Two cables of 0.05Ω

each will drop a total of 0.3V at 3 Amps.)

Quad-Mode Dual versions

The 32V-1A, 32V-2A and 32V-3A sup-

plies are each available as a dual unit in-

corporating push button selection of four

different modes of operation.

Safety and protection

PL series PSUs are designed and built to

meet the stringent requirements of

IEC348 and IEC1010.

All outputs are fully protected against

short circuit, reverse voltage and reverse

currents.

Isolated

Completely independent operation of

each supply.

True Parallel

Converts the Master unit into a 2 Amp,

4 Amp or 6 Amp supply respectively.

Series Tracking

Series

The Master unit voltage control sets up

equal voltages on both supplies.

Internal linking of the two supplies pro-

viding up to 64 Volts.

Quad Mode Triple versions

Each of the quad-mode dual models is al-

ternatively available as a triple supply in-

corporating one further independent

output.

PL330QMT

A wide range of models

Variable output voltage (4V to 6V) and

variable current limit (0.1A to 7A).

The PL series includes single, dual and

triple output models from 35 Watts up to

240 Watts.

Digital meter for current measurement

and voltage setting.

This is a higher current 5 Volt output in-

tended for powering logic circuits.

See the model selector guide for a sum-

mary of voltage and current combinations.

Remote sense terminals, DC output

switch, over-voltage trip.

The current rating and sophistication of

the logic output varies according to the

model as follows:

The PL series is part of a wider range of

bench PSUs from Thurlby Thandar

which includes models with current ca-

pabilities up to 20 Amps.

PL310QMT

Fixed 5V supply at 1.5A maximum.

Full short-circuit protection.

PL320QMT

Variable output voltage (4V to 6V) and

variable current limit (0.1A to 4A).

Calibrated voltage control.

Remote sense terminals, DC output

switch, over-voltage trip.

Thurlby Thandar PL-P series

programmable power at surprisingly low cost

PL-P series

The Thurlby Thandar PL-P series offers

a high performance fully programmable

power supply system at low cost.

Simple and consistent

control

PL-P series supplies use simple and

consistent command structures which

make programming particularly easy re-

gardless of which interface is used.

Based around the 32V-3A versions of the

standard PL series, the PL-P models in-

clude single, dual and triple output units

suitable for bench or rack mounting.

is exclusive to Thurlby-Thandar instru-

ments.

It differs from conventional RS-232 in

that it allows multiple instruments (up to

32) to be controlled using the normal

RS-232 or RS-422/423 port of a PC.

A National Instruments LabWindows*

device driver is available as an option.

When not connected to the bus, these

PSUs can be operated exactly as a stan-

dard PL series PSU.

ARC provides a low-cost alternative to

GPIB which utilises lower cost instru-

ments, inexpensive cables, and can be

controlled by any personal computer

without the need for a special interface

card or special software.

ARC, an exclusive Thurlby

Thandar innovation

ARC stands for “Addressable RS-232

Chain” and is a low-cost system for link-

ing instruments together so that they can

be controlled and monitored by a per-

sonal computer.

GPIB and RS-232 (ARC)

interfaces

Each PL-P series supply is fitted with

both a GPIB (IEEE-488) interface and an

ARC (addressable RS232) interface as

standard.

* LabWindows is a trademark of National

Instruments Corporation.

The ARC interface is an extension of the

industry standard RS-232 interface and

Both interfaces provide full bus control of

voltage and current settings along with

full readback of actual current and volt-

age levels.

The GPIB interface conforms fully with

IEEE-488.2 as well as IEEE-488.1. The

ARC interface can be used as a conven-

tional RS-232 interface or as part of a

multi-instrument ARC system.

On dual and triple output models a single

bus address controls all outputs.

Fully isolated outputs for

maximum flexibility

Each output is fully floating and is opto-

isolated from the bus interfaces.

Outputs can be linked in series or parallel

to produce higher voltages or higher cur-

rents as required.

High resolution control

and readback

● Full bus control and readback of voltage and current.

● GPIB interface conforms to IEEE-488.2.

Voltage and current levels can be set via

the bus to a resolution of 10mV and 1mA

for each main output.

● ARC (Addressable RS-232) interface for low-cost

PC based control.

The 7 Amp logic output of the PL330TP

can also be set to a resolution of 10mV

but the current control resolution is lim-

ited to 1 Amp steps.

● Can be operated as a conventional bench PSU.

● Single, dual and triple output models available.

Each main output can be read back via

the bus to a resolution of 10mV and

1mA.

● Triple output model incorporates fully controllable

high current logic output.

● Rack mounting kit (4U) available for all models.
