SALIENT CHARACTERISTICS FOR POWER RECTIFIER

ITEM DESCRIPTION

AC INPUT: 480 Volts, 3 Phase, 60 Hertz

TRANSFORMER: Dry type core and coil assembly with copper conductors installed and wired as an integral component of the main rectifier system.

AC TAPS: (2) 2.5% FCAN & FCBN taps

AC SWITCHGEAR: 3 pole molded case circuit breaker.

DC SWITCHGEAR: Molded case circuit breaker wired to serve as a 2 pole DC disconnect

DC OUTPUT: 125/250 Volts, 1200 Amperes, 300 kW 3 wire output (neg / neutral / positive)

COOLING: Forced Air

REGULATION: Output voltage will be regulated be the transformer impedance causing the output voltage to increase by roughly 8% between full and no load.

CONTROL: Un‐regulated power supply consisting of a rectifier transformer and diode bank.

RIPPLE: <5% AC RMS at rated Voltage and Current with a resistive load with no provisions included to mitigate imposed AC ripple on the DC output.

ENCLOSURE: NEMA 3R enclosure. Lifting eyes for crane use. Total weight estimate is 4300lbs.

FINISH: Corrosion resistant enamel paint. ANSI 61 gray.

EFFICIENCY: ~ 94% at full rated output current and voltage

POWER FACTOR: ~ 96% at 100% load at rated input voltage

BUS WORK: AC and DC bussing is terminated internally.

METERS & INDICATORS: Meters and basic controls mounted directly on the front of the cabinet.

REGEN CIRCUIT: Optional

LIFTING EYES: To be Safety Factor of 6:1 (2 pad eyes must be able to lift the unit if two other Pad eyes failed during a lift)

FORKLIFTABLE: To have incorporated at the bottom of the unit Forklift Slots for “Lifting” where required.

ESTIMATED WEIGHT: 4,400 lbs.

ESTIMATED DIM’S: 44+‐” X 44+‐” X 69+‐” T
