The CUI Inc. VOFM-5-18 is an AC-DC power supply designed for board mount applications. It delivers a continuous output power of up to 5W with a single output voltage of 18V and a maximum output current of 280mA.
This converter features a universal input voltage range from 85 to 264 Vac and operates within a frequency range of 47 to 63 Hz. Key electrical specifications include an efficiency of up to 76%, line regulation of ±0.5%, and load regulation of ±1%. It also incorporates over-voltage, over-current, and short-circuit protections.
The VOFM-5-18 is housed in a compact 4-DIP Module package and utilizes Through Hole mounting. It operates within an ambient temperature range of 0°C to 70°C with derating and offers 6,565 Vac isolation voltage (primary to secondary).
Designed with medical applications in mind, it meets various safety and compliance standards including TUV EN 60601-1, CE, and UL/cUL 60601-1. It is also compliant with EMI/EMC standards such as EN 55011 and EN 55022.
The input voltage range is 85 to 264 Vac at 47-63 Hz.
The output voltage is 18 Vdc and the maximum output current is 280 mA, providing 5 W of power.
It is a 4-DIP through-hole module (55.0 x 35.0 x 21.0 mm).
The operating temperature range is 0°C to 70°C with derating.
It includes over voltage protection (150% Io), over current protection (180% Io), and short circuit protection with auto recovery.
The isolation voltage is 6,565 Vac between primary and secondary, and 1,500 Vac between primary and transformer core, tested for 1 minute.
The maximum efficiency is 76%.
