The SIL30C Series is a new high density open-frame non-isolated converter for space sensitive applications.
The converter has a wide input range (10.2 Vdc to 13.8 Vdc) and offers a wide 0.9 Vdc to 5 Vdc output voltage
range with a 30 A load. The series offers remote ON/OFF, overtemperature protection and overcurrent
protection as standard. Its current share facility supports parallel operation of multiple SIL30C units and the
remote sense feature enables the SIL30C compensate for voltage drops between the converters output and the
load. With full international safety approvals including EN60950 and UL/cUL60950 the SIL30C reduces
compliance costs and time to market.
