SKL SKH The SKA standard range for printed circuit board is extended with products in hybrid technology ( Direct Copper Bonding (*) ) with : By courtesy of Aavid Thermalloy --> 230VAC and 400VAC SKA models built with 50A back to back thyristors which can drive a 6A permanent current and sustain very high surge current : 600A/20ms and I2t >1800A2s. --> SKL range for mounting on heatsink with 16, 25, 50 and 75A power element size . With these SSRs you can drive loads with high inrush current. The nominal current is limited by the size of the heatsink and the printed circuit board ( generally 25/30A).( For example : you can drive a load with a nominal current of 25/30A according to the printed circuit board and the heatsink , but with an inrush current ≥ 75A during few seconds) --> SKH range with a small heatsink cliped on the SKL products . SKH can drive a 10A permanent current, extended to 25A with forced air cooling. 10 SKL on a PCB and cliped on a heatsink Exemple mounting : see application note This range is particularly designed for heater , incandescent lamps and motor control . These SSRs can sustain very high surge currents ( up to 1000A/10ms and 5000A2s) , therefore they can easily be protected against short-circuit of the load and can drive loads with high inrush currents. Many applications like motor switching (pump controls , motor reversing ,SSRs integration inside the motor connections box,...), transformers, food equipment ( coffee machines , pizza ovens,... , lamps ( infrared lamps, traffic lights, lightning, ...), medical equipments , ........ As all celduc SSRs, this range is built with high immunity components in compliance with european standards, with very low zero cross voltage,.......... (*) The first advantage of DCB technology (Direct Copper bonding) is the thermal performances , but the main adavantage is the increasing of the lifetime expectancy , mainly on loads with high inrush currents. celduc All technical characteristics are subject to change without previous notice.

They are specified in : * Thermal current ( Ie or Ith) depending on the heatsink size. * Itsm : Maximum surge current into the SSR. For each reference see curves on the data-sheets. Use a varistor accross the SSR's output. In the note below , some exemples are given for different types of loads. Ph Ph mounting SK model VDR on the PCB Charge / Load Ou / Or SSR SK model VDR on the PCB Charge / Load SSR N N When the load is cold , the starting current can increase at a maximum of 1,4xIn. In a normal case , with fuses protection ( see application note : SSRs protection) , choose the SSR in compliance with the nominal current and the starting current. Generally a SKL on printed circuit board is limited at about 25A due to the PCB and the connectors. In case of a protection by MCB , you must use I2t SSRs : 1800 or 5000A2s heating load .Exemples :2000W/230VAC : In = 8,7A --> 16A SSR is acceptable : SKH20120 : 6KW with 3 resistors on 3x400VAC line / protection by MCB --> 9A/phase ==> 3 SKL20540 + 2,6K/W + MCB 16A Z curve AC-51 infrared lamp Incandescent lamps ( infrared ,....) : AC-55b have generally inrush currents up to 8 or 10 times the nominal current . You can use the curve Itsm = f(t) , and take a good margin to have a correct lifetime expectancy. Exemple : lamp 1500W/230VAC : In = 6,5A --> SKL20520 : 50A rating. Electric discharge lamp : AC-55a have also high inrush current , but in addition , there are overvoltage at the turn OFF . ---> Use 400VAC SSRs for 230VAC loads and add a varistor to protect the SSR. AC-55 motor AC-53 transformer AC-56b others loads Squirrel cage motors : AC-53 have generally inrush currents up to 5 or 8 times the nominal current . Standards give 8 x In during 1,6s . --> Adapt the SSR to the motor nominal current x 8 Exemple : Three phase motor :2,2KW /400VAC IAC-53 = In = 5A ---> Id = 40A Use 3 SKL20540 ( one by phase) and 3 VDRs ( 420V size 14) See application note on transformer control. Depending on the transformer type , the inrush current can reach 100 x In. It is better to use random SSRs. Check the inrush current into the transformer . A good method is to measure the primary resistor, because when the transformer is satured , the current is near U/r. With 75A SKL ( repetitive Itsm : 500A/20ms) , it is possible to drive transformers with very high inrush currents. In all cases, you must respect the maximum current at turn-ON , the thermal caracteristics when running and the maximum overvoltage at turn-OFF. SSRs with 1600Vpeak can be delivered for specific applications like PFC , UPS,............ celduc r e l a i www.celduc.com s Rue Ampère B.P. 4 42290 SORBIERS - FRANCE E-Mail : [email protected] Fax +33 (0) 4 77 53 85 51 Service Commercial France Tél. : +33 (0) 4 77 53 90 20 Sales Dept.For Europe Tel. : +33 (0) 4 77 53 90 21 Sales Dept.
