Magnum RD3924 Inverter/Charger Specification Sheets

The Powerful DifferenceReliable Off-Grid Power from Magnum EnergyThe RD Series Inverter/Charger from Magnum Energy is a new generation inverter designed specifically for renewable energy use. The RD Series is powerful, easy-to-use, and best of all, cost effective.Power Factor Corrected (PFC) Charger: Our PFC charger is built into all of our inverter chargers. It uses less energy from a generator than a standard charger – using 25-30% less AC current than standard chargers.Safe and reliable: The RD Series is ETL Listed to the stringent requirements of UL 1741, ensuring that the inverter is safe and reliable.Easy-to-install: Install the RD Series in four easy steps: simply connect the inverter’s output to your distribution circuits or electrical panel, connect your power cable (AC) to the inverter’s easy-to-reach terminal block, connect the batteries, and switch on the power.FeaturesYou asked and Magnum listened. The RD Series Inverter/Charger is loaded with features:Choices: The RD Series comes in four power models and 12 and 24 volt models, allowing you to choose the model that is right for you.Versatile mounting: Mount the RD Series on a shelf or wall. Lightweight: The lightweight aluminum base and cover also provides noise reduction and corrosion resistance.Multiple ports: The RD Series provides multiple ports, including an RS485 communication port for network expansion, and a remote port.Accessible design: The extra large AC access cover with terminal screw block and 360° DC connection terminals with covers make this inverter more accessible when it needs to be.Convenient switches: The RD Series comes with an on/off inverter-mounted switch with an easy-to-read LED indicator.Expanded transfer relay: 60 Amp transfer service is available on all models.Buy with ease: The RD Series is backed by a two-year (24-month) limited warranty.Accessories and Options*Remote control: For convenient finger-tip operation, including the new one-knob™ programming.AGS module: Automatically starts and stops your generator based on temperature or battery voltage.The RD Series Inverter/ChargerThe RD Series Inverter/Charger is powerful, easy-to-use, and cost effective.* For more detailed information and specifications on these accessories, please see the accessories data sheet.For Renewable Energy ApplicationsMODEL NUMBERS:RD2212RD1824RD2824RD3924AVAILABLE FOR:Renewable Energy Systems Off-grid Power Back-up PowerAVAILABLE ACCESSORIES:AGSBattery Monitor KitDC Load DisconnectFuse BlocksRemoteRemote Switch AdapterSeries Stacking Interface????????????The Powerful DifferenceRD2212 RD1824 RD2824 RD3924Inverter SpecificationsInput battery voltage range 9 - 16 VDC 18 - 32 VDC 18 - 32 VDC 18 - 32 VDCNominal AC output voltage 120 VAC 120 VAC 120 VAC 120 VACOutput frequency and accuracy 60 Hz ± 0.005% 60 Hz ± 0.005% 60 Hz ± 0.005% 60 Hz ± 0.005%1 msec surge current (amps AC) 60 70 100 150100 msec surge current (amps AC) 37 40 60 905 sec surge power (real watts) 3700 4000 6000 900030 sec surge power (real watts) 3450 3300 4800 64005 min surge power (real watts) 3100 2850 3950 580030 min surge power (real watts) 2400 2400 3500 4750Continuous power output at 25° C 2200 VA 1800 VA 2800 VA 3900 VARated input battery current 191.0 ADC 88 ADC 133 ADC 188 ADCInverter efficiency (peak) 95% 95% 94% 93%Transfer time 16 msecs 16 msecs 16 msecs 16 msecsSearch Mode .2 ADC .3 ADC .3 ADC .3 ADCNo Load (120 VAC output) 0.87 ADC .5 ADC .6 ADC .6 ADCWaveform Modified Sine Wave Modified Sine Wave Modified Sine Wave Modified Sine WaveCharger SpecificationsContinuous output at 25° C 110 ADC 50 ADC 80 ADC 105 ADCCharger efficiency 85% 85% 85% 92%Power factor > 0.95 > 0.95 > 0.95 > 0.95Input current at rated output (AC amps) 15 15 21 29General Features and CapabilitiesTransfer relay capability 2 legs at 30 A for 120 V/30 A or 240 V/60 A serviceFive stage charging capability Bulk, Absorb, Float, Equalize, and Battery Saver™Battery temperature compensation With available temp sensor (battery temp 0 – 50° C)Remote inverter on/off switch With available pigtail to connect to dry contactInternal cooling 0 to 120 cfm variable speed drive using dual 92mm brushless DC fansOvercurrent protection Yes, with two overlapping circuitsOvertemperature protection Yes on transformer, MOSFETS, and batteryConformal coating on PCB’s for corrosion protection YesPowder coated chassis & top for corrosion protection YesStainless steel fasteners for corrosion protection YesListings ETL listed to UL1741Warranty Two yearsEnvironmental SpecificationsOperating temperature -20° C to +60° C (-4° F to 140° F)Nonoperating temperature -40° C to +70° C (-40° F to 158° F)Operating humidity 0 to 95% RH non condensingPhysical SpecificationsDimensions (h x w x d) 13.75” x 12.65” x 8.0” (34.9 cm x 32.1 cm x 20.3 cm)Mounting Shelf or wall (vents up)Weight 38 lb (17 kg) 38 lb (17 kg) 42 lb (19 kg) 45 lb (20 kg)Max operating altitude 15,000’ (4570 m)The RD Series Inverter/ChargerSpecificationsAuthorized Magnum DealerMagnum Energy, Inc.1111 80th Street SW, Suite 250Everett, Washington 98203 USATesting for specifications at 25° CSpecifications subject to change without notice.March 2007, Rev B Part #64-0300Phone: 425-353-8833Fax: 425-353-8390Web: www.magnumenergy.com
