Featuring class II isolation levels they can be equipped into non-patient contact medical equipment and still comply with class B as per
EMI regulations. With energy saving and the environment in mind the no load power consumption is lower than 0.5W so that it complies with the requirements for “green mode” power supplies. Standard functions include short circuit, over load and over voltage protections and over temperature protection is equipped on the whole NFM series. Suitable for use in general medical or for industrial usage that require low leakage current, general electronic applications and low profile IT equipment this on-board type PSU’s can be
applied on the main control PCB of the final systems.
