Power ControllersSolid State Relays(SSRs)Lower cost and longer heater life isthe main advantage provided byWatlow solid state relays (SSRs).A unique loop-powered firing cardpermits a very fast time proportionalcycle rate of less than one-tenth of asecond that allows using higher wattdensity heating elements and/orincreasing heater life. In addition,temperature control accuracy isoptimized with this fast cycle card.Watlow SSRs can be ordered with allthe <strong>com</strong>ponents necessary forhassle-free mounting, includingheatsinks, thermal foil and bevelwashers along with semiconductorfuses.Performance Capabilities• Burst firing,10 to 75 amps• Operating environment-25 to 50°C (-13 to 122°F) withproper heatsink• Can switch up to 575VÅ(ac)Features and BenefitsFast cycle card• Heater life is increased,temperature control is optimizedand higher watt density heaterscan be usedZero cross firing a• Minimal electrical noiseBack-to-back SCR design• Will withstand harsh or hostileenvironmentsUL ® recognized, CSA certified,VDE licensed• For applications requiring agencyapprovalApplications• Injection molding• Thermoforming• Extrusion• Blow molding• PackagingaNot available on random fired models.198SpecificationsStandard to all SSRs:Agency Approvals• UL ® 873, File #E151484, E73741• CSA #LR700195• VDE 0805 EN60950,File #90995ÜG• CE 60950Dielectric Strength• 4000 Volts RMSDC Control InputVoltage range• 3-32VÎ(dc), model no. dependent• 4-32VÎ(dc), model no. dependentInput current• 4mA @ 5VÎ(dc)Turn on voltage• 3VÎ(dc) minimumTurn off voltage• 1VÎ(dc) maximumAC Control InputVoltage range• 90-280VÅ(ac)Input current• 2mA max. @ 120VÅ(ac)Turn on voltage• 90VÅ(ac) minimumTurn off voltage• 10VÅ(ac) maximumOutput (Maximum)Forward voltage drop• 1.5VÅ(ac) typicallyMinimum holding current• 50mAÅ(ac)Turn on-off time• 8.3msStorage Temperature• -40 to 85°C (-40 to 185°F)SSR Weight• 0.090 kg (0.21 lb)Shipping Weight• 0.045 kg (1.0 lb)
