N78-2 2A Non-Isolated DC-DC Switching Regulators

MEAN WELL N78-2 2A Non-Isolated DC-DC Switching Regulators offer an efficiency of up to 96% and eliminate the need for additional heat sinking, simplifying heat management for system designers. These 2A devices are fully pin-compatible with the traditional TO-220-packaged 78xx and 79xx linear voltage regulators, facilitating direct replacement. The N78-2 series is especially well-suited for integration into a range of power supplies, electronic instruments, and distributed circuit systems. MEAN WELL N78-2 2A Non-Isolated DC-DC Switching Regulators feature a wide input range of up to 32V in a compact package with short-circuit, overload, and overtemperature protections. The N78-2 components are EAC/UKCA/CE safety approved and comply with BS EN/EN 55032 radiated Class B without additional components.
