pl303qmd-twoidentical outputs as per pl303, with tracking andparallelmodes(see modes section)
pl303qmt -asperpl303qmd plus third output as per pl068 (above)
note:actualmaximafor voltage and current are typically 1% greater thanthefiguresgiven above.
outputsetting&control
voltagesetting:bycoarse and fine controls.
currentsetting:bysingle logarithmic control.
outputmode:constantvoltage or constant current with automaticcross-over.ccindicator inconstant current mode.
outputswitch:electronic,non isolating. preset voltage and currentlimitdisplayed when outputoff. 
output rise time no load <15ms.
v-span (voltage span control)
thevoltageadjustmentrange can be controlled by digital setting oftheend-stop values ofthe coarse voltage control to anydesiredvalues. the range for vmaxis 0.1v to 6v/15v/30v/60vdepending onmodel. 
the range for vmin is 0 to (vmax - 0.1v).
s-lock (settings lock)
voltageandcurrentsettings can be locked by a single button press.lockaccuracy isequal to the meter accuracy (seemeterspecification).
outputperformance
rippleandnoise:normal mode voltage: <0.4mv rms and 2mv p-p; normalmodecurrent:<0.2marms; (<40ua >); common mode current:<5ma rms
loadregulation:voltage- <0.01% + 2mv. current - typically 0.01%+500ua.
voltagespecificationappliesfor any load change, measured at the outputterminals. whenusingremote sense add 0.5mv per 0.1v drop in thepositive outputlead(max. sense lead resistance0.5 ohm).
lineregulation:voltage<0.01% + 2mv for 10% line change. current <0.01% + 250ua.for 10%linechange.
transientresponse:<50msto within 50mv of setting for a 90% loadchange.
temp.coefficient:voltage:typically <(50ppm +0.5mv)/oc; current: typically<(100ppm+1ma)/oc; 
(100ppm + 0.1ma)/oc on 500ma range.
outputprotection
outputprotection:outputwill withstand forward voltages of up to 20vabove ratedoutputvoltage. reverse protection by diode clamp forcurrents upto3a.
over-temperature:outputtripsoff for over-temperature.
safetyinterlocks:operationsthat could cause an unpredictable change involtage orcurrentsettings are interlocked with the outputswitch.
outputconnections
outputterminals:universal4mm safety binding posts on 19mm (075)spacing.
terminals can accept fixed shroud 4mm plugs, standard 4mmplugs,forkterminals and bare wires.
remotesense
senseselection:voltagesensing can be selected as local or remote byfrontpanelswitch.
senseterminals:sprungloaded screw-less terminals.
modesofoperation(pl303qmd/qmt only)
the pl303qmd and pl303qmt have fourmodesofoperation - independent, isolated tracking,isolatedratiotracking, and true parallel.
independent: the twooutputsarecompletely independent and electrically isolatedfromeachother.
tracking: the twooutputsremainelectrically isolated, but the voltage control of themasteroutputsets an identical voltage on theslaveoutput.
ratio tracking: as tracking,buttheslave voltage can be set to to any percentage of themasteroutputand will retain that percentage ratio as the mastervoltageisvaried.
parallel: all of the power(upto180 watts) is channelled to the master outputwhichcanconsequently supply up to 6 amps. the slave output isturnedoffand its meters are blanked.
both on/both off: the bothonandboth off buttons are in addition to the individualswitchesforeach output, and allow both outputs to be turned onoroffsynchronously by a single button press.
meterspecifications
displaytype:dual4-digit meters, 10mm (039) led.
