Setec BMS-001 battery monitor
15 March, 2011 byThe BMS-001 is a battery monitor that continuously monitors 12 V lead acid batteries, acting as a ‘fuel gauge’, to estimate the state of charge and time remaining to discharge.
Linear Technology LTC2990 IC temperature and voltage monitor
19 October, 2010The LTC2990, an I2C temperature and monitor for 3 and 5 V systems, is a highly integrated monitor that incorporates a 14-bit ADC, a 10 ppm/°C voltage reference and I2C digital interface to provide sub millivolt voltage resolution, as well as ±1°C accuracy internally and ±0.5°C accuracy remotely when making temperature measurements.
Linear Technology LTC2911 three-channel supply monitor
19 October, 2010Linear Technology Corporation has introduced the LTC2911 three-channel supply monitor with power-fail warning for low-voltage systems down to 0.5 V. In certain applications, monitoring the main input supply is just as important as monitoring the intermediate bus voltages to provide the host with an early warning of supply failure and signal shutdown procedures.
Maxim MAX11068 battery-monitoring IC
16 September, 2010 byMaxim has introduced the MAX11068, a high-voltage, 12-cell, battery-monitoring IC for hybrid vehicles, electric vehicles and any system that stacks long series strings of batteries. It employs a SMBus-laddered communication bus that allows multiple 11068s to be daisy chained together without isolators.
Innovative Energies No-Break DC (i) series battery charger
23 January, 2010The No-Break DC (i) series battery charger has been designed primarily to remotely monitor battery-backed control systems.
North Atlantic iPM DSP-based intelligent power monitor & control unit
18 January, 2010 byNorth Atlantic Industries (NAI) has released a next-generation, DSP-based intelligent power monitor and control unit. The model iPM monitors single- or 3-phase wye or delta connected power lines for voltage, frequency, phase sequence, THD and DC component. When any of these parameters are outside of their preprogrammed limits, the iPM internal 10 A relay opens and disconnects the power from the load. The device has a universal input voltage range of 80 to 230 RMS and a universal input frequency range of 47 to 800 Hz. It includes a background self-test capability that constantly monitors the health of the unit.
Battery management
19 October, 2009 byMicrochip Technology has announced two families of charge-management controllers featuring overvoltage protection to prevent overheating and damage to the battery-charger circuit from input-voltage spikes.
Battery management IC
17 September, 2009 byInternational Rectifier has introduced the AUIRS2003S 200 V IC for low-, mid- and high-voltage motor vehicle applications including a pre-charge switch and stepper drives and DC-DC converters
AC power meters
16 September, 2009 byMurata has introduced a series of four-function AC power meters. The ACM20 series can measure and display AC volts, amps, watts and power factor with a typical accuracy of ±0.5% full-scale. The meters accurately display true-RMS voltage and current values of triangle and square waves plus other irregularly shaped waveforms.
Energy monitoring
17 June, 2009 bySiemens has added to its range of power management devices with the Sentron PAC4200 multifunction power monitoring device.
