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. See Table 1 for

single phase, DC, 3 phase/3 wire, or 3 phase/4 wire.

 To connect, use #8 ring lugs with 30A rating.
 Grounding stud provided for ground connection(s) to the right of TB1.
 A fault-clearing device, such as a fuse or circuit breaker, with a maxi-

mum rating per Table 1 at the power supply input is required for
safety agency compliance.

Table 2. Inhibit/Enable Logic Table

 Use ITT/Cannon mating connector P/N DE15PK87.
 Use 20-24 AWG stranded wire.

Output Connections

Installing ring lugs on output bus bars:

 When viewed from the rear, the upper left output lug

is Return and the lower right output lug is Positive.

 Place ½” or smaller bolt through output lug and ring

lugs from load cables and install retaining nut.

 Tighten the nut to a torque of 10 ft/lbs.

Sense Connections

 The Javelin III is equipped with Auto-Sense (load sensed at output lugs if remote sense is not connected).
 Connector pin J1-13 is the +Remote Sense and J1-14 is the –Remote Sense.
 If Remote Sense is desired, connect pin J1-13 to the positive load connection and pin J1-14 to the negative

load connection at the point where regulation is desired.

 Attach sense terminals to load using 20-24 AWG stranded, twisted pair wire.
 Verify that sense lines are not cross-connected.

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.

Its inherent flexibility comes from its use of Vicor 2nd Generation DC-DC converters. Javelin III has three 90
CFM fans for cooling.

Standard Features

 Power Factor Correction: .99 at 115 VAC; .95 at 230 VAC.
 Universal Input: 85-254 VAC, 47-500 Hz, or 85-380 VDC.
 Power Output: Approximately 5400W at 230 VAC for selected outputs; 2400W at 115 VAC. See Graph

1(Pg. 11) for breakdown of input voltage vs. output power.

 Full power to 55C; half power at 70C. See Graph 2 (Pg. 12)
 Soft start for limiting inrush current.
 EMI Compliance: FCC Class A & EN 55022 Class B; MIL-STD-461E.
 Transient Protection: MIL-STD-704E.
 Environmental: MIL-STD-810E.
 MIL-STD-1399 (300A); 115VAC, 60Hz, Single Phase; ≥1KVA<5KVA.
 Harmonic Distortion to EN61000-3-2.
 AC Power OK status signal.
 Fan cooled.
 Equipped with Auto-Sense.
 Output overcurrent, overvoltage and overtemperature protection.
