GENERAL SPECIFICATIONS

Input and Output Ratings
Three-phase ARR chargers have 208, 240 or 480-volt input. DC outputs are either 130 volts at 50 to 500 amps or 260 volts at 25 to 250 amps.

Standard Control Modules
All ARR chargers, regardless of size, use the same plug-in printed circuit boards. This minimizes parts inventory and simplifies maintenance.

Regulation
DC float voltage is maintained within ±0.5% from no load to full load with input frequency variations of ±5% and with ac input voltage variation as shown.

Current Limiting
The current limiting circuit is factory set at 105% and is adjustable from 75% up to 115%. It will hold down to short circuit.

Power Factor
The typical power factor varies from 66% at +10% AC line to 80 percent at –10% AC line under full load conditions.

Electrical Noise (Filtered Chargers) Filtered to 100mVrms when connected to a battery with an eight hour capacity rating of four times the charger DC current rating.

Electrical Noise (Unfiltered Chargers) Nominal ripple is approximately 3% rms on unfiltered units when connected to a battery with an eight hour capacity of four times the charger DC current rating.

Off-Battery Operation
All three-phase filtered ARR chargers can be operated on a principally resistive load with the battery disconnected for maintenance purposes. The RMS ripple will be greater than with the battery connected.

Paralleling
All three-phase ARR chargers can beoperated in parallel with other constant potential chargers having similar regulation characteristics of the same nominal DC output voltage.

Circuit Protection
A three-pole AC input circuit breaker is provided on all models. A two-pole DC circuit breaker is provided in the output circuit.

AC Power Failure Alarm Relay
The AC power fail alarm closes a single-pole Form C contact to operate a variety of local or remote alarms in the event of an AC failure.

High DC Voltage Shutdown
An adjustable DC high-voltage shutdown relay shuts down the charger if it senses a voltage above its set value.

Float and Equalize Voltage Controls
Two, multi-turn potentiometers provide the adjustment range. Selection is made with a toggle switch.

Meters
The DC ammeter and DC voltmeter have 3.5-in (89-mm) cases, 2.9-in (74-mm) scales and 2% accuracy.

Ambient Operating Temperatures
Three-phase ARR chargers will operate at current limiting continuously in temperatures from 32F to 122F (0C to 50C). These units can be stored for up to one year at temperatures ranging from -40F to 185F (-40C to 85C).

Finish
Electrostatically applied, baked epoxy powder finish (ANSI-61 gray) resists scratches, nicks, acid, and corrosive fumes.

Cooling
All models are natural convection cooled.

Mounting
All models are floor mounted.

OPTIONAL FEATURES

Low DC Voltage Alarm Relay – Alarm operates when the charging voltage falls below a pre-set level. Available with time delay.

High DC Voltage Alarm Relay – Alarm operates when the charging voltage goes above a pre-set level. Available with time delay.

Equalize Timer (with indicating light) – 0-255 hour timer replaces float-equalize switch. Charger automatically returns to float at end of time interval.

DC No-Charge Alarm Relay with forced load sharing – DC no-charge alarm relay with forced load sharing operates when charger DC output current is less than 2 percent of rated output. Provides load sharing within ±5% for all three-phase ARR chargers with the same nominal DC output voltage and current. Recommended when chargers are operated in parallel.

One Percent Accuracy Meters – both voltmeter and ammeter have same size scale and case as standard two percent meters.

Summary Alarm Relay – The summary alarm relay combines the signals from several individual alarms and activates if one of the alarms is activated.

DC Ground Detection Relay – Operates when resistance from output to ground is less than 10,000 ohms. Can be used for either remote or local indication.

Ground Detection Lights with Two Push-Button Switches – Shows whether ground is in (-) or (+) output line.

Ground Detection Momentary Switch - Disconnects DC voltmeter from output circuit and measures voltage to common ground.

Lightning Protective Device – Provides added input protection against lightning-induced transients.

Drip Shield -Protects charger from dripping water without interfering with convection cooling.
