... DC-DC converters. This gives designers the freedom to choose from the industry’s broadest selection of DC-DC converters with outputs from Vdc, 50 – 600 Watts. The user need only provide external hold-up capacitors, a few discrete components, and a line filter (available from Vicor). ...

... ELECTRICAL CHARACTERISTICS Electrical characteristics apply over the specified operating voltage range, output load and baseplate temperature, unless otherwise specified. All temperatures refer to the operating temperature of the baseplate. Specifications apply for AC mains having no more than 5% total harmonic distortion. INPUT SPECIFICATIONS (HAM-xL, HAMD-xL, BAMD-xL) ...

... On a nominal 115 Vac line, the output voltage of the HAM is 280 Vdc — well within the input operating voltage range of Vicor V375 DC-DC converters. Above 180 Vac input, the output voltage linearly increases with input voltage. At 230 Vac the delivered voltage will be aproximatly 365 Vdc ...

... HAM, see page 8. Connect single phase AC mains to the input of the line filter via 250 V fuse. Connect the output of the filter to L1 and L2/N of the HAM. Do not put an X-capacitor across the input of the HAM or use a line filter with an X-capacitor on its output as power factor correction may be impacted. +IN, – ...

... If the AC line fails, E/O goes low when the DC output of the HAM drops below 250 Vdc. E/O must be connected to the Gate Input of all VI-26x and VI-J6x drivers and / or the PC pin of the V375 DC-DC converters (Figure 4); failure may cause the converters to toggle on and off external load is connected directly to the output of the HAM, do not apply the load until the output hold up capacitor(s) are fully charged ...

... E/O signal of the HAM. This provides sufficient time for the converters to turn on and their output(s) to stabilize prior to P/OK being asserted, (Figure 9). For momentary interruptions of AC power, the HAM will provide at least ride through or hold up time (with 1,000 µF output capacitor). On loss of power or brownout ...

... PIN FUNCTION / DESCRIPTION (CONT.) Line Filter for High Boost HAM A line filter is required to provide attenuation of conducted emissions generated by the HAM module and to protect it from line transients. It also presents a well defined high frequency AC line impedance to the input of the HAM. To meet the listed specifications, Vicor’ ...

... The HAM is not isolated from the line – either input or output; a line isolation transformer must be used when making scope measurements. HAMs do not provide input to output isolation. Differential probes should be used when probing the input and output simultaneously to avoid destructive ground loops ...
