Convection-cooled 600-W programmable supplies from TDK-Lambda certified to medical and industrial standards

The TDK-Lambda GXE600 600-W programmable ac-dc power supplies are convection cooled and certified to the medical IEC 60601-1 and industrial IEC 60950-1 and IEC 62368-1 standards. The GXE600 is suitable for medical, industrial, test and measurement applications requiring wide-range output voltage and current programming, with sensitivity to noise from cooling fans.

The GXE600 is available with a nominal 24-V or 48-V output and can be programmed, using the RS-485 interface (Modbus RTU protocol) or an external 0 – 6 V analog signal, for constant voltage and constant current (CVCC) operation. The programming range is 20% to 120% for the voltage and 20% to 100% for the current. In addition, the parameters for fault programming (protection level and recovery characteristics) and the slew rate timing can be changed. Remaining electrolytic capacitor life, operating hours and alarm history can be read through the RS-485 interface, aiding remote preventative maintenance.

Accepting an 85 to 265-Vac input, the 95% efficient power supplies can start up at -40°C and operate in ambient temperatures ranging from -20 to +70°C (derating linearly to 50% load above 50°C). Additional derating or external cooling is required for operation below 170 Vac input at full load. As standard the GXE600 has a 5-V standby voltage at 1 A, isolated DC Good and AC Fail signals, remote on/off and paralleling capability for up to five units. Overall dimensions are 127 mm wide, 41 mm (1U) high and 254 mm in length. A seven year warranty is also provided.

The series has been certified to IEC/ES/CSA/EN 60601-1, IEC/UL/CSA/EN 60950-1, IEC/UL/CSA/EN 62368-1, EN 62477-1 (OVC III) and carries the CE mark for the Low Voltage, EMC and RoHS Directives. All models meet IEC 60601-1-2 Ed4:2014, EN 55011-B, EN 55032-B, FCC Class B, VCCI-B emissions and immunity standards. The earth leakage current is <300µA, input-to-ground isolation is 1,500 Vac (1 x MoPP), input-to-output 4,000 Vac (2 x MoPP) and output-to-ground 1,500VAC (1 x MoPP) for suitability with B and BF rated equipment.
