KS28 is a dual AC solid state relays, that two completely independent AC output solid-state relays are integrated in a standard panel package. The product control voltage offer (4~15)VDC and (15~32)VDC two type, load voltage 240VAC and 380VAC, load current divided to 25A, 40A and 50A. Using optical isolation between input and output, and with built-in RC snubber circuit. The product can be used for heating, lighting control and other occasions.

1.Make sure that the polarity is correct when connecting, to avoid damage to the relay.
2.Apply heat-conducting silicon grease or a thermal transfer pad on the space between SSR and heat sink. Then, screw the
heatsink firmly. In that case, it would keep the SSR from damaging by overheat.
3.Install an adequate heatsink or take other effective cooling measures, when the relay is working. Please refer to the curve of
Max. Load Current vs Ambient Temperature.
4.Please do not use the relay beyond the descriptions in the data sheet.
