The QBVS050A0B series operate from an input voltage range of 52 to 60Vdc and provide up to 50.0A output current at output voltages of 12.0Vdc in an industry standard, DOSA compliant quarter brick. The converter incorporates digital control, synchronous rectification technology, a fully regulated control topology, and innovative packaging techniques to achieve efficiency exceeding 97% at 12.0V output. This leads to lower power dissipations such that for many applications a heat sink is not required. Standard features include on/off control, output overcurrent and over voltage protection, over temperature protection, input under and over voltage lockout. The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Built-in filtering for both input and output minimizes the need for external filtering. * Trademark of General Electric Company # UL is a registered trademark of Underwriters Laboratories, Inc. † CSA is a registered trademark of Canadian Standards Association. ‡ VDE is a trademark of Verband Deutscher Elektrotechniker e.V. § This product is intended for integration into end-user equipment .

This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architecture. 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 25A in the ungrounded input lead of the power supply (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.

Highly inductive source impedance can affect the stability of the power module. For the test configuration in Figure 9, a 680μF electrolytic capacitor, Cin, (ESR<0.7 at 100kHz), mounted close to the power module helps ensure the stability of the unit. 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 Note: Measure input reflected-ripple current with a simulated requirements of the end-use safety agency standard, i.e., source inductance (LTEST) of 12 µH.

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. pin and one V pin are to be grounded, or  One VIN 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 Note: Use a 1.0 µF ceramic capacitor and a 10 µF aluminum or tantalum capacitor.
