KS33 is a set of SPST-NO type DC output solid state relays, using common panel mounting, offer (3 ~ 32)VDC input control and use MOSFET output. It is available with switching current 50A at 30V, 100A at 30V, 40A at 50V,80A at 50V, 20A at 100V, 40A at 100V, 80A at 100V, 50A at 150V, 10A at 200V, 40A at 200V, 10A at 400V, 7A at 500V and 12A at 500V etc.It is optical isolation between input and output, dielectric strength 2500VAC.
Features:
● MOSFET output
● Photoelectric isolation
● Low on-state resistance
● Dielectric strength 2500V
● Panel mount
● Input DC control
Precautions:
1.Diode is a must for Inductive loads.
2.When choosing a SSR,please pay more attention to actual load current and ambient temperature. When the SSR is used for full load operation, we must install an adequate heatsink or take other effective cooling measures. When the ambient temperature is high, please refer to the curve of Max. Load Current vs Ambient Temperature for derating. 3.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.
4.Tighten the SSR terminal screws properly. If the screws are loose, the SSR will be damaged by heat generated from connections. Also, excessive screw mounting torque may damage relay internal components. We recommended screw installation torque as follows: M4 screw mounting torque of (0.98~1.37)N·m, M3 screw mounting torque of (0.58~0.98)N·m.
5.Please do not use the relay beyond the descriptions in the datasheet.
