Description

t(s) Packaged in ISOTOP modules, the MSS40 /

MSS50 Series is based on two back-to-back SCR

uc configurations, providing high noise immunity.

d They are suitable for high power applications such

ro as solid state relays, heating control systems,

welding equipment, motor control circuits...

te P The compactness of the ISOTOP package allows

le high power density and optimized power bus

connections. Thanks to their internal ceramic pad,

so they provide high voltage insulation (2500 VRMS),

b complying with UL standards (File ref: E81734).
