SIL30C Series

12Vin single output

per Telcordia SR-332

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 to 13.8Vdc) and offers a

wide 0.9V 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 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.
