2.7kW 1U Full-Rack Programmable AC-DC Power SupplyDecember 02, 2019 by Paul Shepard
TDK Corporation announces the introduction of the TDK-Lambda 1U full-rack 2.7kW programmable ac-dc power supply series. Adding to the already released 1.7kW, 5kW, 10kW and 15kW platforms, the 2.7kW platform provides the user with a choice of ten different models, ranging from 10V-265A to 600V-4.5A, that have advanced performance and functionality well suited for design, test and measurement within the laboratory/R&D environment and address broad market segments including automotive, aerospace, semiconductor, industrial and renewable/alternative energy.
Built into a lightweight 1U high, 19” (483mm) wide rack-mountable chassis, the 2.7kW ac-dc power supply series offers five embedded front panel setup menus that offer user-selectable functions including internal resistance simulation, slew-rate control of output voltage/current, constant-power limit and arbitrary waveform generation.
All models have three ac input options which include a single-phase 230Vac input (with 0.99 PF), a three-phase 208Vac input (with 0.94 PF) or a wide-range 400Vac/480Vac input (with 0.94 PF), and have conversion efficiencies up to 90.5% with cooling fan speed control (for reduced audible noise and extended life).
Standard safety features include user-selectable safe-start/auto re-start and last setting memory along with other built-in protective functions including output over-voltage protection, output under-voltage limit, output under-voltage protection, fold-back protection for CV or CC mode, output over-current limit and over-temperature protection.
A new advanced parallel master/slave system allows for up to four units to be connected in parallel with auto-configuring technology and provides dynamic response and output voltage ripple/noise characteristics comparable to that of a single unit.
All model functions can be programmed locally via the menu-driven front panel display or remotely using software instrument drivers with any one of the three built-in standard Digital interfaces (LAN (LXI 1.5), USB (2.0) and RS-232/RS-485). Other programming interfaces include the built-in standard Isolated Analog Program/Monitor/Control Interface, the optional IEEE (IEEE 488.2) and ModBUS-TCP Digital interfaces.
The 2.7kW power supply series carries a five (5) year warranty, has safety certifications to IEC/EN/UL/cUL 60950-1 and has the CE mark in accordance with the Low Voltage, EMC (IEC/EN61204-3; industrial environment) and RoHS Directives.
