Description

The EHHD006A0B Series, eighth-brick, low-height power modules are isolated DC-DC converters that provide a single, precisely regulated output voltage over an ultra-wide input voltage range of 18-75V voltage rated for 6A

output current. The module incorporates GE’s vast heritage for reliability and quality, while also using the

. The EHHD006A0B provides 12Vdc nominal output

latest in technology and component and process standardization to achieve highly competitive cost. The open frame module construction, available in both surface mount and through-hole packaging, enables designers to develop cost and space efficient solutions. The module achieves typical full load efficiency greater than 92% at V

=24Vdc and greater than 90% at VIN=48Vdc.

Standard features include remote On/Off, remote sense, output voltage adjustment, overvoltage, overcurrent and overtemperature protection. An optional heat plate allows for external standard, eighth-brick heat sink attachment to achieve higher output current in high temperature applications.

CAUTION: This power module is not internally fused. An input line fuse must always be used.

This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architectures. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast-acting fuse with a maximum rating of 10 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum DC input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.

Design Considerations

Input Filtering

The power module should be connected to a low AC impedance source. Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 7, a 33-100μF electrolytic capacitor (ESR<0.7 at 100kHz), mounting close to the power module helps ensure the stability of the unit. Consult the factory for further application guidelines.

Safety Considerations

For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL60950-1, CSA C22.2 No.60950-1, and VDE08051(IEC60950-1).

If the input source is non-SELV (ELV or a hazardous voltage greater than 60 Vdc and less than or equal to 75Vdc), for the module’s output to be considered as meeting the requirements for safety extra-low voltage (SELV), all of the following must be true:

 The input source is to be provided with reinforced

insulation from any other hazardous voltages, including the AC mains.

 One V

pin and one V

pin are to be grounded, or

OUT

both the input and output pins are to be kept floating.

 The input pins of the module are not operator

accessible.

 Another SELV reliability test is conducted on the whole

system (combination of supply source and subject module) as required by the safety agencies to verify that under a single fault, hazardous voltages do not appear at the module’s output.

Note: Do not ground either of the input pins of the module

without grounding one of the output pins. This may allow a non-SELV voltage to appear between the output pins and ground.

The power module has extra-low voltage (ELV) outputs when all inputs are ELV.

All flammable materials used in the manufacturing of these modules are rated 94V-0 or tested to the UL60950 A.2 for reduced thickness.

For input voltages exceeding –60 Vdc but less than or equal to –75 Vdc, these converters have been evaluated to the applicable requirements of basic insulation between secondary DC mains distribution input (classified as TNV-2 in Europe) and unearthed SELV outputs.

The input to these units is to be provided with a maximum 10 A fast-acting fuse in the ungrounded lead.
