The standard & P
versions
The Thurlby- Thandar TSX se ries rep re -
sents the state of the art in high out put
PSU de sign.
A wide range of voltage- current out put
com bi na tions will be come avail able with
power lev els of 360 Watts and more.
Each out put com bi na tion is avail able in
two ver sions: with con ven tional ana -
logue con trols (TSX) and with pro gram -
ma ble con trols (TSX-P).
Linear post regulation for
unrivalled performance
The heart of all TSX se ries PSUs is an
in no va tive regu la tor de sign which com -
bines switch mode pre- regulation with
lin ear post- regulation.
The pre- regulator uses spe cially de vel -
oped tech niques to dra mati cally re duce
the ca paci tance be tween in put and out -
put thus elimi nat ing the high lev els of
common- mode noise nor mally as so ci -
ated with switch mode PSUs.
The lin ear post- regulator com bines very
low lev els of out put noise with ex cel lent
load regu la tion and tran sient re sponse.
The re sult is per form ance com pa ra ble
with a pure lin ear de sign.
Compact and lightweight
The hy brid regu la tor de sign pro vides a
PSU which is both smaller and lighter
than com peti tive prod ucts.
The high ther mal ef fi ciency also means
that the PSUs are si lent in op era tion
since fan cool ing is un eces sary *.
Bench or rack mounting
The at trac tively styled cas ing takes up
very lit tle bench space and in cor po rates
a tilt bail to an gle the front panel when
re quired.
The case is half rack width (3U height), an
op tional rack- mount kit is avail able.
Out put ter mi nals are fit ted at both front
and rear.
* Note that in rack en vi ron ments with
lim ited ven ti la tion fan cool ing may be -
come nec es sary.
Constant voltage or
constant current operation
All TSX se ries PSUs can op er ate in both
con stant volt age and con stant cur rent
modes with auto mat ic cross over and
auto mat ic mode in di ca tion.

the limit set tings can be checked at any

A damp ing switch for the cur rent me ter
en ables the av er age value of rap idly
