Selectable charge rates range 10mA to 30A
Continuous maximum output power rating, 1008W @ +24VDC input voltage, 516W
Using +24VDC to +32VDC input, 1008W output will deliver full current rating (30A)
over the full range of output voltage up to 33.6V
Smart power management allows customer to select between programmable input
power sources. Using the Charge Control Software (CCS), choose from several tem-
plates to get you in the ballpark, then fine tune the settings. Available settings include
power supply input current limit, input low voltage limit, regenerative discharge rate
and voltage limit. PowerLab 8 stores 1 set-up for Power Supply and 1 set-up for
Battery and asks for verification one time on start-up
PowerLab 8 supports charging through node wires only (automatic current limiting to
3A maximum) or node wires in combination with discharge wires (charge rate support
Initiate charge, discharge, monitor, and multiple cycles at the PL8 or via remote
from the CCS. Graph all major operations when using CCS.
Open Architecture presets allow for customization of any User Preset including
show/hide presets on unit, preset name editing, up to 100 parameters control how
presets are displayed and charging/discharge/cycling parameters associated with
charging strategies. Unit includes 25 user preset banks
pre-loaded for most major battery type/chemistries, plus 50 library presets.
Environmentally friendly, industry first, regenerative discharge capability of up to
1000w. Unlike traditional methods of discharge, which deplete the output battery’s
energy in the form of heat across a transistor, regenerative discharge takes most of
that energy and puts it back into the input battery. In other words, when you discharge
your LiPo for storage, you will be re-charging your Lead Acid input battery. The total
amount of power that you can achieve is limited only by the amount of current that
your input battery can accept, or 1000W, whichever is lower.
PowerLab 8 is also equipped with a traditional, 100W internal discharge capability
10AWG silicon input power cable and heavy-duty, removable plier clips
Massive sendust core toroid capable of 50A continuous input current requirement for
Supports native Cellpro batteries automatically
Adapters available for all popular R/C battery brands
Available opto-isolated PC interface and free Charge Control Software (CCS)
Sleek and attractive high-impact ABS enclosure for maximum airflow efficiency
Sturdy Aluminum top panel with reliable, recessed tactile buttons
Quick “preset over-ride access” to common charging parameters like setting charge
and discharge current and operational modes of charge/discharge/monitor/cycle(s)
Additional advanced options menu for adjusting in-depth charging parameters and
GUI PC software (CCS) allows access to 25 User Presets and 50 Library Presets
stored in the unit or available in unlimited number on the P.C.
Free and reliable firmware updates for the life of the product using the CCS
Automatic Low voltage restore for recovering damaged or over-discharged packs
Programmable options allow speaker ON/OFF or volume, LCD contrast, customized
Cold weather mode reduces end-charge voltage; parameters adjustable by customer
including ON/OFF, end-charge voltage offset reduction, and temperature
Multiple product cases can be interlocked
Future provisions for master/slave mode whereby one PowerLab 8 master can control
one or more slaves, send over preset information, control all aspects of charging and
balancing. This feature is perfect for charging multiple packs of same chemistry and
capacity using multiple devices such as split packs connected in series during opera-
