The K7805-500R3 is the successor of the K7805-500R2 version. This improved DC/DC converter is pin-compatible but weighs less, is both UL60950 as EN60950 approved and has a wider input voltage. This high efficiency switching regulator doesn’t need a heat sink and is widely used in industrial control, instrumentation and electric power applications.
