1.7kW Single-Phase Input AC-DC Programmable Power Supply

TDK Corporation announces the introduction of the TDK-Lambda 1U full-rack 1.7kW ac-dc programmable power supply series. This platform provides the user with a choice of ten different models, ranging from 10V-170A to 600V-2.8A, that have advanced performance and functionality well suited for design, test and measurement in the laboratory and R&D environments 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 1.7kW power supply series offers five embedded front panel setup menus that address digital communication, protective functions, operating configuration, system configuration, and system triggering.

These embedded menus offer user-selectable functions including internal resistance simulation and slew-rate control of output voltage/current and have the capability to generate, store, recall and activate up to four on-board arbitrary waveform profiles.

All models can operate in Constant-Current (CC), Constant-Voltage (CV) as well as the newly offered Constant-Power (CP) limit and have conversion efficiencies up to 90%. Operation from a single-phase input of 85- to 265-Vac is standard along with built-in power factor correction (0.99 typical) and cooling fan speed control (for reduced audible noise and extended life).

Standard safety features include user-selectable safe-start/auto restart and last setting memory along with other built-in protective functions (OVP, UVL, UVP, FOLD-CV, FOLD-CC, OCL and OTP) and up to four units can be connected in parallel with an auto-configuring Advanced Parallel system that provides dynamic response and output voltage ripple/noise characteristics comparable with 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 and the optional IEEE (IEEE 488.2) Digital interface.

The 1.7kW power supply series carries a five (5) year warranty, has safety certifications to IEC/EN/UL/cUL 60950-1 and has CE marking in accordance with the Low Voltage, EMC (IEC/EN 61204-3; industrial environment) and RoHS2 directives.
