Relays / Current Monitoring RelaysSolid State Relay 25A 40A DC To DC/DC To AC Input 3-32VDC To Output 5-220VDC/24-480VAC Single Phase SSR With Heat Sink 1PcsWhat You GetEach package include 1*solid state relay,1*aluminium heat sink and 2*screws.Parameter DetailSolid state relay SSR-25DA/40DA/25DD/40DD, Input voltage: 3-32VDC ; Output voltage: 24-480VAC/5-220VDC ; Current rating & Frequency 2540Amps 5060Hz.Wide Range ofApplicable Widely used in automation and automation control of petrochemical plants, food machines,packaging machines, textile machines, machine tools, plastic machines,entertainment possibilities.Product Name:Solid State Relay with Heat SinkMaterial:ABS plastic, Metal, CopperLoad Current:25A/40AControl Voltage:3-32VDCLoad Voltage:5-220VDC 24-480VACOn-off-Time: 10msMouting Method: Screw fixedAmbient Temperature: -20~+75Package Contents1*SSR 40DA1*Black heat sink2*ScrewProduct FeatureSolid state relay with flame-retardant plastic housing, epoxy casting compound, sturdy and with compact appearance.Used with aluminum heat sink to effectively reduce the high temperature generated by relay operation.SSR switches use semiconductor component acts as a switch for the relay, connection by screw terminals,high strength, impact resistance and vibration resistance, with low requirement for input current.It is specially designed for harsh environments with corrosion, humidity or light-proof/explosion-proof requirements and frequent turn-on/off requirements.They can be easily connected with digital control circuits of computers.They are updated products of AC and DC contactors.Selection NotesStep 1: Select control methodDA: DC controlACDD: DC controlDCStep 2: Calculate Current MagnitudeEquipment Current / Coefficient=Selection CurrentSelection Current×Coefficient=Equipment CurrentThe coefficient is determined by the type of load of the device you want to connectResistive load: 0.5;Inductive load: 0.15Attention:Solar equipment is a mixed load, we do not recommend using solid state relays.If you want to try, you need to buy a solid state relay with 10 times the current.At the same time, if the solid state relay does not work normally on the solar equipment, we do not provide return service.NOTICE:The inside of the solid-state relay is a semiconductor. A semiconductor switch is a non-physical contact switch. if use a multimeter diode or resistor to test ,it always show a high-impedance state, (multimeter light red).According to the conventional detection methods of solid state relays: a load is required to test the switching state. Using an incandescent as a dummy load is an obvious way to test continuity.How to use thermal greasesteps are as follows: 1.Wipe the back of the SSR clean to the . 2.Squeeze some thermal grease on the SSR back. 3.Use the brush to spread the thermal grease. 4.Apply thermal grease evenly.Theory : Solid State RelayContact Load : Low PowerFeature : SealedControl Voltage : 3-32VDCLoad Current : 25A/40AAmbient Temperature : -20~+75
