L. Battery Monitor System

BATTMASTER is the first wireless (license free), low cost battery monitoring system. It can be used in various applications such as: UPS, TELECOM, ELEVATORS, and CRITICAL BATTERY POWERED SYSTEMS. Use it for: Protecting mission critical systems Evaluating battery compliance with the systems Dimensioning new battery based systems Supporting claims related to system behaviorIt will dramatically improve control over the battery operating conditions, battery failure prediction, system reliability, installation, maintenance and operating costs, flexibility for the system extension.

BATTMASTER measures and stores battery voltage, temperature, current and internal resistance data for up to 1024 batteries/system. User settable alarms related to these parameters can be generated through email, LAN or GSM. The build-in clock helps you to keep a precise history of the monitored parameters.

BATTMASTER has a good measurement precision and a complete, user-friendly database. The recorded data can be easily transferred and processed as spreadsheets or graphs. BATTMASTER powerful user software allows a precise analysis of the logged data and eases your decision making process.
