Javelin III Power Supply Operator’s Manual Javelin III Power Supply AC-DC Switcher Javelin III Power Supply “Quick Install” Instructions Mounting the Javelin III Power Supply The Javelin III can be mounted at either of two surfaces (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. Input Connections Input Barrier Strip (TB1) Input AC or DC power is applied to barrier strip TB1.
Javelin III Power Supply Operator’s Manual Status/Control/Sense Connector (J1) 15 J1-1 and J1-9 are Signal Return pins. J1-2 is VCC +5V @ 300mA. J1-3 is AC Power OK (+5V = True). J1-4, 5 and 12 are not connected J1-5 is +12V fan power. J1-6 is +5V DC (in). J1-7 is DC OK and J1-8 is DC OK′. J1-10 and J1-11 are used in conjunction according to Table 2. J1-13 is +Remote Sense and J1-14 is –Remote Sense.
Javelin III Power Supply Operator’s Manual III Power Supply Power Factor Corrected AC-DC Switcher Overview The Javelin III 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 III can provide up to 5400 watts in a 7.00”H x 16.0”W x 13.0”L package.
Javelin III Power Supply Operator’s Manual Technical Description The Javelin III consists of an off-line single phase or three phase power-factor-corrected front end (or optional DC), with EMI filter, cooling fans, customer interface, associated housekeeping circuits, and a selection of Vicor’s DC-DC converters. Three power supply units are placed in parallel to provide the final output current capability.

Javelin III Power Supply Operator’s Manual Signal Return (J1-1, 9) Signal Return on J1-1 & 9 is an isolated secondary ground reference for all J1 interfacing signals. Inhibit/Enable (J1-10 & J1-11) The Inhibit/Enable control pins allow the output to be controlled with either “inhibit” or “enable” logic. Connecting Inhibit (J1-11) and Enable (J1-10) to ground causes the Javelin III to operate. With Inhibit (J1-11) open, the Javelin III will operate, and the Enable pin has no effect.
Javelin III Power Supply Operator’s Manual DC OK/DC OK′ (J1-7 and J1-8) DC OK and DC OK′ are logic signals provided to indicate with either TTL logic “1” or “0” that the correct output voltage is available. DC OK (J1-7) is a logic “1” when output voltage is within specification and a logic “0” when output is out of tolerance. A logic “0” is capable of sinking 16 mA in either circuit. The inverse signal, DC OK′, is available at J1-8.
