Genesys� Highest Density 2U 5kW Programmable Power from Lambda Americas

Apr 14, 2008

The newest member of the Genesys� product family of programmable switching power supplies provides highest power density, low ripple and a complete set of user-friendly interfaces. Also offered in 750W, 1U Half Rack and 750W or 1500W, 1U Full Rack, 3300W 2U and 10/15kW 3U, it continues the advanced, high-density series of AC/DC, rackmount, programmable power supplies. Outputs available range up to 600V and 1,000A. In addition to saving space, Genesys� power supplies contain extensive standard features that provide a new level of performance and flexibility in ATE, Industrial and Communications applications.

In addition to highest power density, the GEN 2U 5kW offers popular worldwide three phase inputs, 208VAC or 400VAC. They feature Active Power Factor 0.94 typical. This assures operation in difficult AC environments and meets European EMC requirements.

The user-friendly front panel provides reliable control through encoders selectable for fine or course adjustment and four digit LED Voltage and Current meters. Adjustable OVP, UVL and Current Foldback provide further flexibility. Their set values may be previewed on the front panel display with Output ON or OFF. The Foldback may be set to latch output OFF if desired for safety.

New Interface Options

Also included in this release are several important new features and options. Up to four like units may be connected in parallel and user configured for the Master to Program and Monitor the total current of the group. Thus, four units can appear as a single 60kW power supply, increasing flexibility for system designers.

In the Digital Options, an option called Multi-Drop allows an IEEE Multi-Drop Master to control Multi-Drop equipped Slaves over RS485, avoiding the cost of a GPIB board in every slave power supply. Up to 31 may be addressed over the RS485 lines of Master and Slaves.

The newest Digital Option is LXI Class C Certified LAN Ethernet. The interface provides flexible system integration and functionality for system designers. LXI (LAN extensions for Instrumentation) is a next-generation, LAN-based modular platform standard for automated test systems. As a leading supplier of programmable AC/DC Power, Lambda has joined the consortium to increase the functionality, flexibility and performance of the Genesys� series of programmable supplies and to support the development of the LXI standard.

Significant safety features include Safe Re-Start and Last Setting Memory. With Safe Re-Start, the user can select whether the Genesys� power supply returns to previous settings after power off, or returns to zero (safe) output, waiting for user instructions. Last Setting Memory retains settings of output voltage and current, remote or local mode, OVP and UVL, Foldback, Baud Rate and Start Up Mode, without battery. Front Panel controls also include Output On/Off and Local/Remote selection. The Front Panel may be locked locally or by software command.

Like other Genesys � products, the new 2U 5kW Genesys�Series includes standard, embedded 16 bit RS232/RS485 digital interface. Through this digital interface up to 31 power supplies may be controlled in daisy chain over the RS485 line. Analog remote programming is user selectable 0-5V or 0-10V via DIP switches on the rear panel.

The design of Genesys� power supplies is highly modular to offer short lead times. SMT technology provides high reliability.

Digital and isolated analog interfaces are optional. The optional IEEE digital interface is IEEE488.2 & SCPI compliant. Labview Drivers are available. Isolated analog programming options include either 0-5V & 0-10V or 4-20ma control.

Lambda Americas, Inc. is a leading manufacturer of precision, high power and high voltage AC/DC power supplies.
