Technical Description The Javelin consists of a DC or off-line single phase power-factor-corrected front end, with an EMI filter, cool- ing fan (Javelin I), customer interface, associated housekeeping circuits, and a selection of Vicor’s DC-DC con- verters. Input DC or AC mains voltage is applied to a 3-pin power connector. The input current is passed through an EMI filter designed to meet conducted noise limit specification EN55022, level A and B. - Page 5 Javelin I & II Power Supply Operator’s Manual Voltage conversion is achieved by Vicor’s family of Zero-Current-Switching (ZCS) DC-DC converters. These are forward converters in which the main switching element switches at zero current. This patented topology has a number of unique attributes: low switching losses, high frequency operation (resulting in reduced size for magnetics and capacitors), excellent line and load regulation, wide output adjustment range, low EMI/RFI emission, and high efficiency.
- Page 6 Exces- sive cable inductance, coupled with large capacitive loading, can introduce instability in switching power supplies. This problem can be avoided with proper system design. Consult Mission Power So- lutions’ Engineering Department for assistance with applications Positive Return that use long cable lengths and excessive load capacitance.

It is +5VDC 5% with respect to Signal Ground (J2-4 and J2-2) and can supply 300mA maximum. It is short-circuit proof, but if shorted, all outputs will be shut down through the Inhibit/Enable circuitry.
