Brand Name Justification under $250K

PMD Number: FY21- 20637

Department: A

Company Name/Brand: TDK Lambda

Description of Product, Supplies or Services required to meet the agency’s needs:

The TDK Lambda power supplies GEN 40-19-U, GENH 40-19-IEMD-U and GENH 40-

19-U will be used in the to support

Programmable DC Power Supplies feature in leading DC programmable power density

(1.5kW in 1U height), light weight, wide range of AC inputs, output voltage up to 600V, current up to 150A, built-in LAN, multi-drop capability (RS-485), multi-functional front panel display, last-setting memory, high speed programming. These power supplies provide arbitrary waveform generator with auto-trigger capability, programmable slew rate control (Vout/Iout), constant power limit operation, internal resistance programming, built-in remote isolated analog interface, local/remote sensing software control, Isolated Analog Programming etc.

The TDK Lambda power supplies offer both parallel operation - Master/Slave and Series operations.

Parallel operation: Active current sharing allows up to four identical units to be connected in an auto-parallel configuration for four times the output power. In

Advanced Parallel Master/Slave Mode, total current is programmed and reported by the Master. Up to four supplies act as one. Allows IEEE Master to control up to 30

(Multi-Drop equipped) slaves over RS-485 daisy-chain.

o Only the Master needs be equipped with IEEE Interface o IEEE 488.2 SCPI Compliant o Program Voltage, Current o Measure Voltage, Current o Over Voltage setting and shutdown o Current Foldback shutdown o Error and Status Messages o Four Channels to Program and Monitor Voltage and Current.

o Isolation allows operation with floating references in harsh electrical environments.

Series operation: Up to two units may be connected in series to increase the output voltage or to provide bipolar output. (Max 600V to Chassis Ground).

The TDK Lambda key features:

40 Volts DC at 19 Amps DC.

Comes standard with a US Line Cord.

Comes with Standard RS-232/RS-485 Interface (included on all INTERFACE options).

AC input is 85-265VAC, Single Phase Universal Input

Identification of Justification Rational:

☒ The Material or service must be compatible will aspects (Form, Fit, and Function) with existing systems presently installed.

☐ A patent, copyright, proprietary data, or licensing agreement limits competition.

☐ These are “direct replacement(s)” parts/components for existing equipment.

☐ Urgency.

Identification of the Justification Rationale Explained: **If using form, fit, and function, describe the current equipment and how the new item/service must coordinate or interface.

**If using patent, copyright, proprietary data, describe the proprietary data. **If using direct replacement, describe this below.

The Original Equipment Manufacturer (OEM) for the DC power supply is TDK Lambda.

The DC Modular Power System has been integrated into the

An attempt to identify and qualify alternate parts for the manufacturing of equipment that will meet the requirements will cause a substantial duplication of cost to the

Government that is not expected to be recovered through competition. Specifically, the Navy would incur a non-recurring cost approximately in order to identify and qualify alternate sources with the capability to produce the required equipment.

estimate derives from the Tech Refresh efforts from 2011-2016 which included taking steps to ensure that any new sources are capable of producing a product that meets the established performance requirements. This includes the costs for the Government to conduct

First Article Tests, Confidence and Functional testing for form, fit and function. Additionally, the software program would have to be modified, and Shock and Vibration testing would need to be performed. If an alternate part is determined to be qualified, then additional resources would be required as all applicable documentations will need to be updated through Engineering

Change Process (ECP) to introduce the new alternate part. Without the required TDK Lambda power supplies, the Government cannot have a functional which will degrade the state of the system, as the Government will be unable to test the system.

Specific Characteristics of the Item or Service required that Limit the Availability to a Sole

Source or Brand Name: **This is the most important section. Explain in detail why this company or brand are the only ones that can meet the requirement.

The TDK Lambda power supplies are currently part of the Technical Data Package

(TDP) and had been tested and integrated in the . Any other part will not work without vigorous testing to integrate the new part into the system.

Market Research Conducted:

The Government conducted market research from Nov 2020 – Feb 2021 through mandatory sources; GSA, One Touch, and small businesses and identified three vendors who sell the TDK Lambda power supplies, the Original Equipment Manufacturer (OEM), Technical

Communities, Inc. and Allied Electronics Inc.

Statement of Actions, if any to Remove Barriers to Competition in the Future:

NSWC PHD Contracts Office will continue to conduct market research as warranted to provide a broader vendor base as applicable for the types of supplies/services covered by this document. If another potential source emerges, NSWC PHD will assess whether competition for future requirements is feasible.
