POWER

Internal Battery Specifications

960mAh Lithium Polymer, 4.20 Volts fully charged
External Power Requirements
Bus Power8-30 Volts DC, non-polarised, current draw is 190mA maximum at 17 volts per logger
USB Power5 Volts DC
Internal Charge Rate
Bus Power60mA – 200mA Variable internal charge rate, maximum charge rate of 200mA active when the external voltage rises above 16 Volts DC
USB Power100mA fixed charge rate
Internal Power Management
Fully Charged Battery4.20 Volts
