The SIL30 Series is a new high density open-frame non-isolated converter for space

sensitive applications. The converter has a wide input range (10.2 to 13.8Vdc) and

offers a wide 2.5 to 5V output voltage range with a 30A load. The series offers remote

ON/OFF, over-temperature protection and over-current protection as standard. Its

current share facility supports parallel operation of multiple SIL30 units and the remote

sense feature enables the SIL30 compensate for voltage drops between the

converters output and the load. With full international safety approvals including

EN60950 and UL/cUL60950 the SIL30 reduces compliance costs and time to market.
