TDK Corporation announces the introduction of two LAN modules for the TDK-Lambda HFE1600 and HFE2500 series of rack mount, hot-swap power supplies. The LAN (Local Area Network) option allows the user to program and monitor the status of the power supplies remotely. This enhancement is ideal for use in general industrial, communications, and test and measurement equipment.


The LAN modules plug directly into the standard HFE racks and use the HFE/S I2C / PMBus™ function. The HFE1600-LAN is the same size (85 x 41 x 300mm) as the HFE1600 power supplies and plugs in to any open position in the rack. Likewise, the HFE2500-LAN is the same size (107 x 41 x 325mm) as the HFE2500 power supplies. Insertion or removal of modules is possible with the AC present, without disruption to the HFE power supply operation. Communication is possible with either single or multiple supplies in a rack, or with multiple racks.

A GUI (Graphical User Interface), provided via a built-in web server, can program and read back the power supply status. To avoid unauthorised access, users can enable password protection and other security features. Supported protocols include VISA drivers, Telnet, TCP and UDP sockets, plus VXI-11 Discovery and SNMP (Simple Network Management Protocol).

The front panel of the HFE-LAN features an Ethernet RJ-45 connector, a button to reset the LAN back to default settings, status LEDs, and the ability to flash the LEDs remotely to identify the LAN location. Network speed is set manually or automatically to select the fastest of 10Base-T or 100Base-T networks. Configuration of the IP address is also manual or the module will create its own automatically.

The units are safety certified to IEC/EN/UL 60950-1 with CE marking for the Low Voltage and RoHS2 Directives. The operating temperature is -10 to +70oC and the modules conform to the IEC 61000-4-2 immunity standard.
