Programmable fanless power supplies and industrial certification
TDK Corporation is introducing 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 industrial, medical and test equipment requiring quiet operation, fanless cooling and constant-voltage, constant-current programmability.
The GXE600 series can be operated as a 24V or 48V fixed-output supply, or programmed to be provide a constant-voltage, constant-current (CVCC) source. The voltage adjustment range is from 20 to 120 per cent and the current from 20 to 100 per cent. 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.
These power supplies operate from a wide-range input of 85 to 265V AC with an earth leakage current of
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 4000V AC (2 × MoPP), input to ground 2000V AC (1 × MoPP) and 1500V AC output to ground (1 × 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.
