Targeted at the automotive, renewable energy, industrial, medical and applied R&D market segments, a new platform of products from TDK-Lambda Corp. expands the company’s advanced programmable DC power supply series into the 7.5 kW range.
Six new models are available, ranging from 20 V-375 A to 1500 V-5 A. Each is built into a 1U high, 19-inch-wide mechanical profile with benchtop or rack-mount capability, offering high power density and high efficiency (up to 92%) in a lightweight (17-lb) package. Cooling fan speed control is also incorporated for reduced audible noise and extended life.
All models offer three-phase AC input options of 208 V AC (170 V AC~265 V AC) or a wide-range 480 V AC (342 V AC~528 V AC) 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.
Main applications include:
- Battery/component evaluation
- Solar panel evaluation/test
- Subsystem and component test/burn-in
- Medical treatment systems
- Rackmount ATE product validation
- Laboratory product/material research
The new platform also incorporates several advanced adjustable user-selectable functions including constant-power limit operation, internal resistance simulation and slew-rate control of output voltage/current. Waveform profiles of up to 100 steps can be generated and stored in four on-board memory cells and can be recalled and activated via embedded menus on the front-panel display or via remote digital communication.
Standard safety features include user-selectable safe-start/auto restart, 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).
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.
Additional mechanical options include a blank front panel, available for applications where the front panel display and controls are not required, with only remote interfacing being implemented; and an air filter accessory kit to prevent dust entry into the power supply.
