Product Overview and Models

The GenesysPLUS Logo 1U Full-Rack (GenPLUS-1U) series of 5000W DC Programmable Power Supplies provides advanced features and functions in high power density (up to 5200W) and light weight (< 16.5lbs) with a comprehensive set of user-friendly interfaces.

This series offers low-noise performance with Output voltages from 10V (0-500A) to 600V (0-8.5A) in both a three-phase 208VAC Input (170-265VAC, 47-63Hz) and a wide-range three-phase 480VAC Input (342-525VAC, 47-63Hz), both with Active Power Factor Correction (0.94 typical @ rated load).

Advanced features and functions include an Arbitrary Waveform Generator (with Auto-Trigger capability), programmable Slew-Rate control (Vout/Iout), Internal Resistance simulation and Constant-Power Limit programming, which are accessible through a front panel LCD display that has five embedded multi-functional Power Supply Setup menus (that address Digital Communication, Protective Functions, Operating Configuration, System Configuration, and System Triggering).

Multiple built-in standard remote programming methods are available including the built-in Remote Isolated Analog Program/Monitor (5V/10V) & Control and Remote Digital Serial Communication Interfaces (LAN (LXI 1.5), USB and RS-232/RS-485) along with an optional optional IEEE Interface (IEEE 488.2 & SCPI compliant).

Power systems of up to four units in parallel (20kW) utilize on-board auto-configuration for easy system setup and scalable power systems of 10kW and 15kW are also available.

All models are CE Marked in accordance with the Low Voltage, EMC and RoHS2 Directives, have worldwide Safety Agency approvals (UL/cUL 60950-1 and EN 60950-1 listed) and offer a five (5) year warranty.

The GenesysPLUS Logo 1U Full-Rack series of 5000W DC Programmable Power Supplies provides a higher level of programmable power supply performance with advanced features and functions in high power density (up to 5200W) and light weight (< 16.5lbs).

Utilizing embedded microprocessor technology, the GenesysPLUS Logo product platform provides advanced performance and functionality well suited for the Laboratory/R&D environment and addresses broad market segments including Aerospace Test & Measurement, Automotive Component, Module and System Test, Semiconductor Fabrication & Component Test, Industrial and Renewable/Alternative Energy.

Carrying a five (5) year warranty and built into a 1U (1.75”) high, 19” (483mm) wide, and 17.4” (441.5mm) deep rack-mount mechanical profile, the GenesysPLUS Logo 5kW Power Supply Series offers the highest power density (35% higher) and, at 16.5lbs (7.5kg), the lightest weight in the industry (less than half that of comparable products).

Five models are currently available from 10V to 600V with outputs of 10V/500A, 20V/250A, 30V/170A, 300V/17A and 600V/8.5A with conversion efficiencies up to 92%. These units can operate in Constant-Current (CC) and Constant-Voltage (CV) mode and can be power limited with a newly offered programmable Constant-Power (CP) limit function. An Internal Resistance simulation feature is also available to emulate battery source resistance.

Three-phase AC Input options include 208VAC (170~265VAC) and a wide-range 480VAC (342~528VAC) and have built-in Active Power Factor Correction (0.94 typical) with cooling fan speed control (for reduced audible noise and extended life).

In addition to doubling the power density over the existing 2U Genesys™ 5kW Programmable Power Supply Series, the GenesysPLUS Logo 5kW platform offers other significant advancements. These include a high contrast, wide viewing angle multi-segment front panel LCD display (with user controllable brightness and dimming functions for improved readability) that has five embedded multi-functional Power Supply Setup menus that address Digital Communication, Protective Functions, Operating Configuration, System Configuration, and System Triggering. These embedded menus offer new adjustable user-selectable functions including internal resistance simulation (CV mode), Constant-Power limit (CV/CC mode) and Slew-Rate control of Output Voltage/Current. Arbitrary 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 (LAN (LXI 1.5), USB or RS-232/RS-485).

Standard safety features include user-selectable Safe-Start/Auto Re-Start, Last Setting Memory and various built-in protective functions. With Safe-Start configured, the power supply returns to its last operational settings after a power interruption but with the output disabled. With Auto Re-Start, the power supply returns to the last used operation settings after a power interruption. Last Setting Memory retains settings such as the Output voltage/current, Output ON/OFF, Output OVP/UVL/UVP level, Fold-Back (CV or CC), Output Over-Current Limit (OCL) and Start-Up mode (SAFE or AUTO) at each AC input turn-off sequence. Built-in protective functions include 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), AC Fail (AC) and Over-Temperature protection (OTP).

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

All model functions can be programmed locally via the menu-driven front panel display or remotely using one of the three built-in standard Remote Digital communication interfaces (all of whose communication protocols and signals are compatible with the entire TDK-Lambda Genesys™ Series). These interfaces include the LAN (LXI 1.5), USB (2.0) and RS-232/RS-485 and an optional IEEE (IEEE 488.2) Remote Digital communication interface.

All Remote Digital communication interfaces are SCPI-compliant, have Multi-Drop capability (where up to 31 units to be controlled in an addressed RS-485 Multi-Drop configuration) and have a full selection of software instrument drivers along with an Advanced Virtual Front Panel GUI (with Waveform Profiler and Solar Array mode functionality).

A built-in standard Remote Isolated Analog Program/Monitor/Control Interface (with 600V isolation) is also provided with new functions such as Output control pins (for activation of external devices for polarity reversal/load disconnect), Trigger-In/Trigger-Out pins (for synchronization), Enable control (with user-selectable polarity) and higher accuracy Program/Monitor signals.

Two new GenesysPLUS Logo mechanical options are a Blank Front Panel and a Dust Cover. 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 needed. The Dust Cover has a removable snap-in filter (for easy maintenance) and is provided for dusty air environment applications.

The GenesysPLUS Logo 5kW Power Supply Series has Safety certifications to IEC/EN/UL/cUL 60950-1 with CE marking in accordance with the Low Voltage, EMC (IEC/EN61204-3; industrial environment) and RoHS2 Directives.
