1000 cyclesTest conditions (Two-zone, No test halt)High-temp. exposure : +150°C 15 min.Low-temp. exposure : −65°C 15 min.Outside conditions : +23°C/60% rhConsumed power amount to defrost once : 13.6 kWhConsumed power amount to defrost (20 times) : 272 kWhCooling water temp. : +25°CSpecimen : No specimenOPTIONSDefrost-free operationFor two-zone tests, enables continuous testswithout requiring defrosting for up to 500hours max.ESPEC has developed a unique structure(patent: 3514735) that prevents the penetrationof outside air and uses recirculated air duringtesting to stop frosting on the low-temperatureside.This enables continuous tests up to 500 hours,so around 20 defrost cycles during this periodcan be eliminated.This option can reduce both the test time inthe amount of the defrosting time (approx.60 minutes each time) and the powerconsumption required for defrosting(13.6 kWh each time).● 1000 cycles (500-hour) test time comparison exampleEH TypeTest startDefrost operationDefrost-free operationDefrost 1hDefrost 1hDefrost 20 timesDefrost 1h Defrost 1h1000 cycles1000 cyclesTest time20-hour reduction(Defrost 1 hour x 20 times)Powerconsumption amount272 kWh reductionTest conditions (Two-zone, No test halt)High-temp. exposure : +150°C 15 min.Low-temp. exposure : −65°C 15 min.Outside conditions : +23°C/60% rhPower consumed amount to defrost once : 13.6 kWhPower consumed amount to defrost (20 times) : 272 kWhCooling water temp. : +25°CSpecimen : No specimen* The TSA−42EL−A, 72EL−A and 102EL−A have a300-mm protrusion on the top.ModelNumber ofcyclesHigh-temp.exposure/timeLow-temp.exposure/timeOutsideconditionsCoolingwater temp.PowersupplyvoltageSensorpositionSpecimenTemp.recoverytimeTSA-42EL1.5 kgPlastic moldedICs 1.0 kgSpecimenbasket/shelfbrackets 0.5 kgTSA-72EL, ESTSA-102EL, ESTSA-202EL, ESMaximum 500 cycles (Maximum 500-hour)+125°C/30 min.−40°C/30 min.+23°C/60% rh+25°CRated voltageDownstream of specimen5.0 kgPlastic molded ICs 3.5 kgSpecimen basket/shelf brackets 1.5 kg10.0 kgPlastic molded ICs 7 kgSpecimen basket/shelf brackets 3 kgTSA-302EL TSA-72EHMaximum1000 cycles(Maximum500-hour)+150°C/15 min.−65°C/15 min.5.0 kgPlastic moldedICs 3.5 kgSpecimenbasket/shelfbrackets 1.5 kg( ) ( ) ( ) ( )Within15 min.Within 5 min.Within10 min.Within5 min.15

Theoption has a trigger function that switches tothe exposure test after the specimentemperatures reach the temperature setting,so even more precise tests can be run. It canalso record the temperatures of the specimenand the test area when connected to atemperature recorder.(Cannot be combined with Eco operationmode.)· Number of measuring points: 2· Location: Chamber front, left-side panel· Accessor y: Thermocouple type T(copper, copper-nickel) x2** 4 when simultaneously equipped with arecorder16
