DRAFT

Technical Specifications for DOS A-LM Transformers under SBE10017Q5000

Technical Evaluation of Quote Yes/No?

1 220/240VAC to 110/120VAC

2 Auto-Transformer with Red Polarity Warning Light* OR Isolation Transformer

3 Polarity warning light is clearly labeled "Light On, Polarity Reversed"*

4 Ground Fault Interrupter (GFI) safety feature will discontinue input power if any ground fault current or 10 mA or more is sensed**

5 Maximum Wattage: 1000, 2000 (Offer must meet wattage requirements for all line items)

6 Single Phase

7 Unit is thermally protected

8 Portable based on handle, size and weight (Offer must provide dimensional specifications and picture)

9 Indicator Pilot Light (Indicating the unit is ON)

10 Transformer itself possesses label with UL listed or UL recognized symbols or independent testing agency equivalent ***

11 European three-prong SCHUKO plug

Notes:

* Polarity warning light must be clearly labeled on the unit "Light on, Polarity Reversed or comparable"

* Unit that is provided with a Green Polarity OK light is acceptable. Must be labeled. Red polarity OK light is not acceptable.

** To prevent potential shock hazards, customer requires a two-pole Ground Fault Interrupter (GFI) safety feature that will discontinue the supply of input power to the voltage converter unit if any ground fault current or 10 mA or more is sensed.

**The GFI device shall be wired to sense ground fault current paths related to the unit’s metallic components as well as any ground fault paths via connected appliances plugged into the unit’s output receptacles.

*** If other independent listing agency is used, TÜV, CSA, VDE, online verification site information must be provided.

***GOV reserves the right to accept or reject independent agency listing if NOT verifiable online, i.e.. www.ul.com/database , https://www.tuev-sued.de/product-testing/certificates

***Documentation describing labeling as "UL accepted", "UL approved", or "UL certified" alone will not be accepted. The unit must be appropriately marked.

***CE is not a recognized independent testing agency and will not be accepted.

***The submitted technical data must be verifiable against publically available/online information.

Expected Characteristics and Operating Conditions

All internal wiring shall be color coded .

All internal wiring shall be temperature rated to withstand heat generated from transformer.

The transformer shall be suitable for ambient operation between -5 degree C to 40 degree C.

The transformer windings shall be copper not aluminum conductors.

The wiring sizes shall be provided to carry the current carrying capacity of the transformer rating size.

The transformer shall rest on raised non-conducting feet of minimum 2cm to assure no contact with the set up surface.

One transformer must be provided with quote for physical inspection and testing in accordance with FAR 52.214-20 Bid Samples

Failure to meet these specifications will result in an unacceptable rating
