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; for rail mount option, please contact our sales rep.

The units feature a 7000M 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. The series is 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. All models carry comprehensive safety certificates and markings including CE, CB, UKCA, UL, TUV, CCC, etc. that allows the series for global selling.

The HEU250B-F series is highly suitable for the medical equipment or device that is powered by a motor, such as breathing devices, infusion pumps, etc. as the series is designed to feature an enhanced peak power capability to meet the motor starting currents.

Highlights
Compact Size
The size of a power supply usually has a critical influence on the end-equipment design flexibility either on medical equipment or I.T.E. equipment. The smaller the power supply is, the higher the end-equipment design flexibility will be. However, the small footprint design usually faces a technical challenge which is the poor performance of the heat dissipation efficiency and power density.
The HEU250B-F series, on the other hand, provides 25.41W/in3 high power density and an exceptional heat dissipation efficiency while still maintaining the small size of design.
 
300W High Peak Power Sustainability
The HEU250B-F series is the first power supply in Taiwan that covers peak power testing in the CB reports for IEC62368-1, IEC60601-1 Ed. 3.1, and IEC60601-1 Ed. 3.2. The series can sustain peak power up to 300W for tens of seconds due to the enhanced heat dissipation property and improved transient response. The design can particularly satisfy the demands of the medical equipment that is powered by a motor such as breathing devices and hemodialysis machines where high starting currents are required.
 
Wide Operating Temperature
The HEU250B-F series can work flawlessly in extremely hot or cold environments as it offers a wide operating temperature range from -40°C to +70°C.
 
Low Inrush Current
The design of the HEU250B-F series not only reduces the inrush current up to 50% compared with the power supplies on the market but effectively prevents the breakers from tripping and lowers the power loss as well as the working temperature when operating, which leads to better energy saving and a longer product lifetime.
 
High Safety Protection to the Patients & Caregivers
The leakage current can be hazardous if it exceeds the permissible limit especially when in medical applications where a small current might be fatal to weak patients who are more vulnerable to electric shocks.
To ensure the leakage current cannot harm the patients and caregivers who frequently come into contact with the medical devices, the HEU250B-F series is designed to greatly reduce the value of leakage current.
