DESCRIPTION

The HEU250B-F series is a power supply with medical and ITE safety approvals and is protected by a stainless steel cover which ensures a high degree of tolerance against certain compressions or physical impacts. For the HEU250B-F series, a fan is installed inside of the cover to help with heat dissipation.

The series provides 250W output power at efficiency up to 93% with a peak power of 300W and is available in 12v-48v output with options for open frame (2”x4”x1.2”) and cover with fan.

The units feature a 5000M altitude operational ability and can operate in a wide operating temperature range of -40 to +70°C. Meeting the requirements for a 2 x MOPP (Means of Patient Protection) classification, the power supplies offer a compact solution for various medical and ITE applications. They are equipped with overvoltage protection (OVP), overload protection (OLP), over-temperature protection (OTP), short circuit protection (SCP), and approved to IEC/UL/EN/CAN/CSA C22.2 62368-1, IEC/ES/EN/CAN/CSA C22.2 60601-1, RoHS directive, etc.

The power supplies carry comprehensive safety certificates and markings including CE, CB, UKCA, etc. that allows the series for global selling.
