EQ2660-9R电源-外部/内部（板外）的直流转换器规格书PDF中文资料

描述 Description

These extremely compact DC-DC converters incorporate all necessary input and output filters, signaling and protection features, which are required in the majority of applications. The converters provide important advantages such as flexible output power through primary current limitation, high efficiency, excellent reliability, very low ripple and RFI noise levels, full input to output isolation, negligible inrush current, overtemperature protection, and input over-/undervoltage lockout. The converter inputs are protected against surges and transients occurring on the source lines.
