The Cosel GHA700F-48-J1 is an AC-DC open frame power supply designed for industrial and medical applications. It delivers a maximum output of 700W with a 48V output voltage and accepts a wide input voltage range of 85-264V ac.
Key electrical specifications include high efficiency up to 92% at 230V ac input and a power factor of 0.95 typical at 120V ac. The unit features adjustable output voltage, remote on/off control, and standby output. It also includes features like power factor correction, EMI inrush current limiting, overcurrent protection (OCP), and overvoltage protection (OVP).
With a compact footprint of 127mm x 76.2mm x 38.0mm, this power supply is less than 1U high and suitable for chassis mounting. It supports various cooling methods including conduction, convection, and forced air, with operating temperatures ranging from -20°C to 80°C with derating. The GHA700F-48-J1 meets stringent safety approvals such as UL62368-1, EN62368-1, and EN60601-1, making it suitable for BF-type medical applications due to its low leakage current.
The output voltage is 48V.
Under forced air cooling at 50°C, the maximum output current is 6.3A. With convection cooling at 40°C, it is 2.1A, and at 50°C, it is 1.1A.
The maximum output wattage is 700W.
The input voltage range is 85V to 264V ac.
The efficiency is typically 92% at 230V ac input and 89% at 120V ac input.
The operating temperature range is -20°C to 80°C with derating.
It complies with UL62368-1, EN62368-1, EN60601-1 3rd, and IEC60601-1-2 4th edition, among others.
