... 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-xM, HAMD-xM, BAMD-xM) ...

... AC line voltage, Figure nominal 120 Vac line the output voltage of the HAM is 260 Vdc — well within the input operating voltage range of Vicor VI-26x and VI-J6x converters. As input line increases, so does the HAM output voltage; at 220 Vac the delivered voltage will be about 350 V. ...

... 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, – ...

... Enable is asserted high (open state, Figure 8). If the AC line fails, E/O goes low when the DC output of the HAM drops below 195 Vdc. E/O must be connected to the Gate Input of all VI-26x and VI-J6x drivers Figure 4; failure may cause the converters to toggle on and off not necessary to connect this pin to boosters as they are controlled by their respective driver ...

... Figure 7, signaling an impending loss of input power to the converter modules. P/OK will provide power fail warning at least 1 ms prior to converter shut down. When the HAM output voltage drops below 195 Vdc the converters are disabled via Enable Output (E/O). ...

... PIN FUNCTION / DESCRIPTION (CONT.) Line Filter for 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’s P/N 30205 line filter/transient suppressor or equivalent must be used, see Figure 10 ...

... 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 ...
