Javelin I & II Power Supply Operator’s Manual Javelin I & II Power Supply Power Factor Corrected AC-DC Switcher Javelin I & II Power Supply “Quick Install” Instructions Mounting the Javelin Power Supply The Javelin can be mounted at either of two sides (top or bottom). Use #8-32 mounting screws. Maximum penetration should not exceed 0.21″ (5,33mm). Maintain 2″ (50,8mm) clearance at either end for airflow.
Javelin I & II Power Supply Operator’s Manual Output Connections Installing ring lugs on output studs: When viewed from the rear, the left stud is Positive and the right stud is Return. Remove the nut and place .312” ID ring lug over output stud. Replace and tighten the nut to a torque of 130 in/lbs. Do Not Over-Tighten Nuts. DC OK/Sense Connector (J3) The Javelin is equipped with Auto-Sense (load sensed at output studs if remote sense is not connected).
Javelin I & II Power Supply Operator’s Manual I & II Power Supply Power Factor Corrected AC-DC Switcher Overview The Javelin is a ruggedized, switching power supply that combines the advantages of power factor correction and power density with user-selectable output voltage and power. Accepting input voltages of 85 to 254 VAC and 85 to 380 VDC, the Javelin can provide up to 1800 watts in a 4.9 H x 7.0 W x 10.75 L (9.5 L for Javelin II) package.
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.
Javelin I & II Power Supply Operator’s Manual Output Power Connections The output power terminals available on the Javelin are 5/16–18 studs with flanged nuts. The positive polarity of the output is the left stud when viewed from the output end. In order to minimize parasitic cable inductance and reduce EMI, the output power cables should be routed in close proximity to one another, and large current loops should be avoided.
Javelin I & II Power Supply Operator’s Manual Auxiliary Vcc +5V/0.3A (J2-5) The Vcc on J2-5 is an auxiliary 5V regulated power source. 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. +5V/300mA J2-5 Auxiliary Vcc J2-4 Signal Ground J2-2 Signal Ground 78M05 0.1uF Figure 3.
Javelin I & II Power Supply Operator’s Manual Connecting Javelin I & II Power Supplies in Parallel To connect up to three Javelin Power Supplies in parallel, connect PR1 (J3-9) to corresponding PR1(s) (J3-9) and PR2 (J3-4) to corresponding PR2(s) (J3-4). Use 20-24 AWG twisted pair, shielded hook-up cable with the shield connected to each unit’s chassis ground (J3-9). All units must use equivalent power sources, and all outputs must be connected to a common bus with equal impedance connections.
