Lightweight Advanced Programmable DC Power Supply Series Expanded to 7.5kW with 20V to 1500V Models that Deliver High Efficiency, High Power Density and Advanced Features

Neptune, NJ – October, 2022

TDK Corporation (TSE:6762) announces the addition of the TDK-Lambda high power density 1U Full-Rack 7.5kW platform to the Advanced Programmable DC Power Supply Series. Six models are currently available from 20V-375A to 1500V-5A (20V-375A, 40V-188A, 100V-75A, 150V-50A, 600V-12.5A, 1500V-5A) and target the Automotive (eV and Hybrid Subsystem, Battery & Component Test), Renewable Energy, Industrial and Applied Research & Development market segments.

Built into a 1U (1.75”) high, 19” (423mm) wide, and 19.2” (486.5mm) deep bench-top/rack-mount mechanical profile, the 7.5kW Programmable DC Power Supply platform offers the highest power density and high efficiency (up to 92%) in a lightweight package (17lbs/8.5kg) with cooling fan speed control (for reduced audible noise and extended life).

All models offer three-phase AC Input options of 208VAC (170~265VAC) or a wide-range 480VAC (342~528VAC) with built-in Power Factor Correction (0.94 typical) and are capable of Constant-Voltage (CV) and Constant-Current (CC) mode operation with automatic crossover between operating modes.

The 7.5kW platform offers several advanced adjustable user-selectable functions including Constant-Power Limit operation, Internal Resistance simulation, and Slew-Rate control of Output voltage/current. Waveform profiles, such as vehicle battery start-up simulation, of up to 100 steps can also be generated and stored in four on-board memory cells and can be recalled and activated via the front panel display embedded menus or Remote Digital communication.

Standard safety features include user-selectable Safe-Start/Auto Re-Start, Last Setting Memory along with various built-in protective functions such as Output Over-Voltage Protection (OVP), Output Under-Voltage Limit (UVL), Output Under-Voltage Protection (UVP), Fold-Back protection (FOLD) for CV or CC mode, Output Over-Current Limit (OCL) and Over-Temperature protection (OTP).

Local/Remote interfacing is common across the entire product platform (1kW to 15kW) by multiple methods. These include local front panel control, remotely via the built-in LAN (LXI 1.5), USB (2.0) or RS-232/RS-485 Remote Digital interfaces or by use of the built-in Isolated Analog Program/Monitor/Control Interface. Optional rear panel Remote Digital Interfaces include either the IEEE (GPIB), Modbus-TCP or EtherCAT Interface. Instrument software drivers are also available as well as application software that includes a Waveform Creator (to create, store/load and trigger waveform sequence profiles) and a Virtual Front Panel GUI (with Status Logger, Constant Power Limit simulator and Solar Array simulator).

A new Advanced Parallel Primary/Follower system allows for improved multi-unit system performance (Output ripple/noise and dynamic response) where up to four units can be connected in parallel and automatically configured by detection of the parallel data-link cable connections between units, with the Primary unit being the single point for programming, measurement and status of system load current.

Other mechanical options include a Blank Front Panel and an Air Filter Accessory Kit. The Blank Front Panel is available for applications where the front panel display and controls are not required, and only remote interfacing (Digital/Analog) is being implemented. The Air Filter Accessory Kit is available for both standard and blank front panel models, has a removable snap-in filter (for easy maintenance) and is provided to prevent dust entry into the power supply.

The 7.5kW Programmable DC Power Supply platform has Safety certifications to IEC/EN/UL/cUL 61010-1 with CE and UKCA marking in accordance with the Low Voltage, EMC (IEC/EN61204-3; industrial environment) and RoHS Directives and carries a five (5) year warranty.
