6 Issue Date: Page 3 of 49 Report Reference # E A19-UL-2 Amendment GENERAL PRODUCT INFORMATION: CA1.0 CA1.1 Report Summary CB1.0 CB1.1 Product Description The equipment under test is a switch mode power supply, intended to be used in a rack system. The power supply converts 230 Vac to 24 Vdc (nominal) or 48 Vdc (nominal) and communicates with a controller through its own microprocessor. The unit (in a rack system) is typically used to supply other telecommunication equipment, like mobile phone exchanges etc. CC1.0 CC1.1 Model Differences The 48 V, 1800 W version uses main board and the 48 V, 2000 W version uses the main board The two main boards are identical except for minor changes to the layout and component configuration. Flatpack2 24 V is identical to Flatpack2 2000W 48 V, except for the output rating, and minor changes in the secondary circuit. Flatpack2 24V uses main board Flatpack2 A B C BF is identical to Flatpack2 A B C except for reverse air flow, new fans, relocation of temperature sense (NTC201) from the controller board to the main board and change in value for Capacitor (C116) value changed from 220µF to 120 µf. CD1.0 CD1.1 Additional Information See cover page for production sites. The product was investigated to the following additional standards: EN :2001 (which includes all European national differences, including those specified in this test report). Flatpack2 24: Max VA measurements. V=29.1 Vdc, A=85.2, VA=2009 (measured at 25.5 V, 78.8 A) Flatpack2 2000W 48 V: Max VA measurements. V=56.7 Vdc, A=41.2, VA=2016 (measured at V, 38.0 A) Changes made under E A19-CB-3 amendment 2 was performed under SMT program.

62 Issue Date: Page 3 of 18 Report Reference # E A19-UL-2 Amendment GENERAL PRODUCT INFORMATION: CA1.0 CA1.1 Report Summary CB1.0 CB1.1 Product Description The equipment under test is a switch mode power supply, intended to be used in a rack system. The power supply converts 230 Vac to 24 Vdc (nominal) or 48 Vdc (nominal) and communicates with a controller through its own microprocessor. The unit (in a rack system) is typically used to supply other telecommunication equipment, like mobile phone exchanges etc. CC1.0 CC1.1 Model Differences The 48 V, 1800 W version uses main board and the 48 V, 2000 W version uses the main board The two main boards are identical except for minor changes to the layout and component configuration. Flatpack2 24 V is identical to Flatpack2 2000W 48 V, except for the output rating, and minor changes in the secondary circuit. Flatpack2 24V uses main board CD1.0 CD1.1 Additional Information See cover page for production sites. The product was investigated to the following additional standards: EN :2001 (which includes all European national differences, including those specified in this test report). Flatpack2 24: Max VA measurements. V=29.1 Vdc, A=85.2, VA=2009 (measured at 25.5 V, 78.8 A) Flatpack2 2000W 48 V: Max VA measurements.

Additionally testing of Flatpack 2 A B C was not considered necessary based upon previous evaluation under CB Scheme. The CB Scheme Test Certificate ref No. DK-9630-A2 and Report Ref. No.E A19-CB-3 amendment 2 dated were prepared by UL International Demko. The following changes were made under the CB Scheme: Adding of alternative insulation between switch transistors/diodes and heatsink. Adding of alternate nominal output rating marked on rating label for 2000W/48 Voutput model due to marketing purposes, no constructional changes were made. Adding new alternate Rohs compliant part number to L100/L101. Construction of L100/L101 is still the same, the new part number is only for administrative purposes. Update the way the ratings of the models are given. The following tests were conducted: Test Testing Location/Comments Transformer/Insulation Electric Strength ( , 2.9.5) See Electric strength test (5.2.2) Electric Strength (5.2.2) Test results are valid only for the tested equipment.

169 Issue Date: Page 1 of 69 Report Reference # E A19-UL-2 SPECIFIC INSPECTION CRITERIA BA1.0 BA1.1 Special Instructions to UL Representative Special test has been performed on the printing wirring board s protective earthing trace. As a production line test, an Earthing Test shall be conducted on 100% of production units between the ground pin and accessible dead metal parts. The test shall show that the resistance will not be greater than Ohm between input GND connector and Ground. Test shall be carried out as follows:for samples with an appliance inlet only, the test circuit was connected between the grounding lead of the 1.82 m (6 ft) power supply cord and the grounding lead of the printed wiring board taking into account the minimum cross-sectional area of the ground trace. If a grounding lead was not provided, a suitable length of minimum No. 16 AWG wire was used. The test circuit was capable of delivering 2000 A at 48V dc and having a power factor of percent through shorted bus bars with a 30 A service entrance type circuit breaker (CB) in series at the testing terminals. The circuit breaker was connected to the bus bar by 1.22 m (4 ft) of No. 12 AWG wire. The test is continued for 5 seconds unless ultimate results occur; e.g. circuit breaker trips, fuse opens, trace opens, etc. BB1.0 BB1.1 Supporting Documentation The following documents located at the beginning of this Procedure supplement the requirements of this Test Report: A.
