Datasheet

TDK Corporation has announced the introduction of the GXE600 series of 600W rated AC-DC power supplies, certified to the IEC 60601-1 medical safety standard as well as IEC 62368-1. In a 1U high package, these convection cooled products have the ability to be digitally programmed across a wide range using an RS-485 interface (Modbus RTU protocol) or with a 0-6V external voltage.

Target applications are medical, industrial and test equipment requiring quiet operation, fan-less cooling and constant voltage, constant current programmability.

The GXE600 series can be operated as a 24 or 48V fixed output supply, or programmed to be provide a Constant Voltage, Constant Current (CVCC) source. The voltage adjustment range is from 20-120% and the current from 20-100%. Protection and recovery parameters can be set, as can the rise time slew rate. Via the digital communications interface the power supplies can also indicate the estimated remaining electrolytic capacitor life-time, operating run-time and alarm history to enable remote preventative maintenance indication or fault finding.

The power supplies operate from a wide-range input of 85 to 265Vac with an earth leakage current of less than 300µA and dual input fuses as standard. They can be used in ambient temperatures of -20°C to +70°C (-40°C start up), derating linearly above 50°C to 50% load at 70°C. Derating or external cooling is required below 170Vac input.

The fully featured series also has an isolated 5V 1A standby voltage, remote on/off, DC Good and AC Fail isolated signals, with paralleling capability for up to five units. The case dimensions are a compact 127x41x254mm. The warranty period is seven years.

The units are safety certified to IEC/EN/ES/CSA 60601-1, IEC/EN/US/CSA 62368-1, IEC/EN/US/CSA 60950-1, EN 62477-1 (OVC III), with CE marking for the Low Voltage, EMC and RoHS2 Directives.

Input to output isolation is 4,000Vac (2 x MoPP), input to ground 2,000Vac (1 x MoPP) and 1,500Vac output to ground (1 x MoPP) for suitability with B and BF rated equipment. The units also comply with EN 55011-B, EN 55032-B, FCC Class B, VCCI-B conducted and radiated emissions, meet the EN 61000-3-2 harmonics and EN 60601-1-2 (Edition 4) immunity standards.
