The TriMetric battery monitor is designed to assist in battery care, conservation and system maintenance.
It provides information on battery "volts", "amps" and "amp-hours" and "battery percent full" information, based on measuring the amp-hours removed from the battery system. Reliability, accuracy and simplicity are key product objectives. The TriMetric requires an external shunt located near the batteries to measure "amps" and "amp-hours". The meter may be located anywhere in your coach.
Optional Lightning Protector extends warranty to include lightning strikes.
TM-2025 improvements over TM-2020
- The TM20205 is easier for you to program the necessary system parameters.
- The TM2025 has some minimal data logging, which can be useful for a technician to diagnose some common setup or operational problems with battery systems.
- The TM-2025 will operate with (nominal) battery systems from 12 to 48V. The TM-2020 will operate with 12 or 24 V systems, but requires the addition of the TM-48VA Adapter and lightning protection board when using it with 48V battery systems. This also provides lightning protection for the TM-2020.
- The TM-2025 can also monitor the voltage only of a second battery, such as a starting battery, or possibly also the input voltage of a solar array (if less than 100 volts.)
- The TM-2025 has a simplified level of operation suitable for most users, but can be configured for more flexibility (and complexity) where occasionally required.
- (For the technically knowledgeable only): It has a serial data output of all the real time datawhich could be used to access data for other control or output in, for example OEM applications.
- The newer TM-2025 includes better lightning protection.
- It is easier to view and enter programmed parameters..
- It is about typically about $15 more than the TM-2020. For 48V systems it is less expensive than the TM-2020 because it does not require an extra 48 volt adapter.
There are three possible choices for the TriMetric: TM-2020, TM-2020-RV, TM-2020-A.
