Laboratory DC Power Supplies
The technology leader
TTi is one of the world’s major producers of laboratory power
supplies (PSUs).
TTi has been a major technology innovator in PSUs since 1979
and now offers products ranging from 15 watts up to 1200
watts.
Hundreds of thousands of TTi power supplies are in everyday
use around the world.
Power technologies
TTi laboratory power supplies use both linear and switch-
mode technologies in order to optimise performance and
value for money.
Linear regulation
Pure linear regulation still provides the lowest output noise
and best transient response. The disadvantage is greater
physical size and weight for a given power, together with
higher heat output.
Mixed-mode regulation
For higher power levels, TTi have developed a technology that
uses switch-mode pre-regulation and linear final regulation.
This technique combines exceptional efficiency with noise
levels that are close to that of pure linears.
PowerFlex regulation
The TTi PowerFlex system uses a modified form of mixed-
mode regulation to provide higher levels of current when the
voltage is set to lower values.
Although producing slightly higher noise levels than the
standard mixed-mode regulation, performance is still
excellent.
Measurement and control
Digital Metering
All TTi power supplies incorporate separate digital meters for
voltage and current.
On most models these are 4 digit scale length with fixed
resolution (e.g. 0.00V to 56.00V). Fixed resolution avoids the
misinterpretation of readings that can occur with autoranging
3 or 3½ digit meters where the decimal point position moves
as the reading changes.
QL and QPX models provide 5 digit meters for voltages to give
still higher precision and resolution.
QL and New PL models also include a low current range which
provides 0.1mA resolution.
Remote Sense
Most TTi power supplies incorporate remote sense terminals
that can be enabled or disabled at the flick of a switch.
Remote sensing is essential to maintaining precise regulation
at the load and true metering of the load voltage. Many
other power supplies omit remote sense, but quote regulation
figures that could never be achieved in a practice.
N.B. A 2 meter length of a 24/0.2 wire pair has a resistance of around 0.1 W.
For a 5V load drawing 3A the metering error would be 0.3V and the effective full
current load regulation would be around 6%, against a quoted figure of perhaps
0.01% for the power supply itself.
Output On/Off Switches
All TTi power supplies incorporate output on/off switches for
the main outputs. This enables voltage and current settings
to be viewed before the load is connected and allows multiple
outputs to be controlled individually.
Many other power supplies omit this essential feature.
Analog or Digital Controls
TTi power supplies offer a choice of true analog controls or
digital controls (numeric keyboard and/or spin-wheel).
The New PL Series combines true analog controls with
advanced digital features such as S-Lock and V-Span.
The QL and QPX series offer 16-bit digital control and five
digit metering with a resolution of 1mV.

Bus programmable models
As well as the large range of manually
controlled power supplies, TTi also
offers many bus programmable units
incorporating varying combination of RS-
232, GPIB, USB and LAN interfaces.
LabView or LabWindows drivers are
available for most power supplies.
Silent Cooling
Most TTi power supplies use convection
cooling thus removing the need for a fan
and providing silent operation.
Certain models which offer particularly
high power density (e.g. EX4210R) use
fan-blown cooling to limit temperature
rise in the power section.
Additionally, the QL series of high
precision linear power supplies uses
fan cooling to minimise power related
temperature variation within the precision
analog circuitry.
Rack mounting
Many TTi PSU series, both bus
programmable and manual, have a rack-
modular casing size.
Rack mounts are available for the PL, QL,
TSX, CPX, QPX and New PL series.
Safety binding-post terminals
In response to changing customer
requirements, TTi has introduced a new
terminal design to most of the power
supply range.
The new terminals accept a 4mm
safety plug with rigid insulating
sleeve, a requirement specified
by an increasing number
of laboratories for safety
reasons.
However, unlike the usual
4mm safety sockets, the
new TTi terminals can also
accept fork connectors or
bare wires, giving maximum
flexibility.
