鈥?Over-sized thyristor ratings
鈥?Direct-copper bonding technology
DESCRIPTION
These solid-state single inline package (SIP) relays
are designed for mounting on printed circuit boards.
The Series LS relays facilitate heat sinking by
providing an interface surface. The relays are
designed with 16A, 25A and 50A thyristors. They can
switch loads with high starting currents. The nominal
switched currents depend on the size of the heat sink
and are limited by the cross section of the tracks of
the printed circuit (mainly 25A/30A). The relays use
a direct-bonded copper substrate for thermal
efficiency, thermal stress performance and long-life
expectancy.
APPLICATIONS
鈥?Motor control 鈥?Pumps, reversing, integration of
relays in terminal boxes
鈥?Lamp control 鈥?Infrared drying, traffic lights,
theater lighting
APPROVALS
All models are UL recognized.
UL File Number: E128555.
