425W Power Supplies with Approvals for Various Applications



SL Power announced two new series of power supplies, the MU425 series for medical equipment and TU425 series for critical industrial, test and measurement equipment. These high-performance U-channel power supplies are ideal for equipment that must continue to perform in environments where AC power may be noisy or unstable.

The MU425 and TU425 power supplies measure 3.3 x 6.2 x 1.62 inches (mm) and can deliver up to 425 watts of power with forced air cooling or 300 watts with convection cooling. They accept a universal input range from 90 to 264 Vac and deliver nominal output voltages of 12, 18, 24 and 48 volts (and a 56 volt model in the TU425 series). They provide a 5 V at 2 A standby output and 12 V fan output.

The MU425 series is approved to CSA/EN/IEC/UL60601-1, 3rd Edition, offers 2xMOPP isolation and meets EN61000-4-2, EN61000-4-3 and EN61000-4-6 requirements for home healthcare applications. It is one of SL Power’s range of medical power supplies for equipment that saves and sustains lives.

The TU425 series is approved to CSA/EN/IEC/UL60950-1, 2nd Edition, is compliant to high levels of EMC per EN61000-4 and meets Class B conducted EMI with 6db margin and Class A radiated EMI with 3db margin. It is one of SL Power’s range of critical industrial, test and measurement power supplies for equipment that enables precision.

These safety approvals and EMI/EMC characteristics make it easier for OEMs to integrate SL Power’s MU425 and TU425 power supplies into their end products. An optional cover enables OEMs to enhance the safety of their products, particularly if that equipment is serviced in the field and service personnel need to be protected from a live power supply.

The MU425 and TU425 families are available from SL Power’s worldwide network of authorized distributors.
