Digital accuracy and convenience
TS se ries units in cor po rate digi tal me ters with 3.5 digit LCD dis-
plays to provide greater accuracy and resolution than other
PSUs.
Sepa rate me ters are used for volt age and cur rent, elimi nat ing
the need for me ter func tion switches with their at ten dant prob-
lems of mis in ter pre ta tion.

Greater resolution and control
The TS se ries sets the stan dard for sim ple and com pre hen sive
con trol. Volt ages are set with coarse and fine con trols for speed
with pre ci sion. Cur rents are set with a semi- logarithmic con trol
for in creased reso lu tion at low cur rents.
With the out put switch 鈥榦ff鈥?the cur rent limit set point is dis played.
With the out put switch 鈥榦n鈥?the ac tual out put cur rent flow ing is
displayed.
This in valu able fea ture al lows deli cate cir cuits to be pro tected

liamps if nec es sary) bef ore con nect ing the cir cuit un der test.
LOGIC OUTPUT (3023S only)
Out put Volt age Range: 4 to 6 Volts
Out put Cur rent:
4 Amps mini mum; cur rent limit ap proxi mately 5 Amps.
Out put Switch:
Iso lates the out put and per mits out put volt age to be
set bef ore con nect ing the load.
Out put Ter mi nals:
4mm ter mi nals on 19mm (0.75") spac ing.
Over- voltage Pro tec tion:Dual- speed cir cuit giv ing typi cally 20msec to 7 Volts
and typi cally 2usec above 7 volts. Auto mati cally re set
by mains switch.
Out put Pro tec tion:
Clamped by the over- voltage pro tec tion cir cuit for for
-
ward volt ages over 7 Volts and up to 3 Amps. Di ode
clamped for re verse volt ages at up to 3 Amps.
Load Regu la tion:
<0.5% for 50% load change.
Line Regu la tion:
<0.5% for 10% line volt age change.
Rip ple and Noise:
<20mV rms, <50mV pk- pk.
Me ter Type:
0.5" 3.5 digit LCD for volt age or cur rent.
Me ter Reso lu tion:
Volt age - 10mV, Cur rent - 10mA.
Me ter Ac cu racy:
Volt age - 0.5% of read ing + 1 digit
Cur rent - 0.5% of read ing + 1 digit.
Constant voltage or constant current
TS se ries units can op er ate in con stant volt age or con stant cur-
rent mode (not TS3023 logic out put).
Remote sense for high current precision
TS series units in cor po rate in te grated band- gap ref er ence di-
odes as the ba sis for sta bi li sa tion of both volt age and cur rent.
Re mote sense ter mi nals en able the pre ci sion to be main tained
at high cur rents by elimi nat ing the ef fects of con nec tion lead re-
sistance.
With out re mote sense, lead re sis tance of just a few tens of mil li-
ohms can se ri ously de grade regu la tion and pro duce mis lead ing
re sults. (Two ca bles of just 0.05鈩?each will drop a to tal of 0.3V
at 3 Amps)
