Bogart Engineering TriMetric 2020 48 Volt Adapter and Lightning Protector

Manufacturer Part Number: TM-48VA

The TM-48VA adapter will adapt a TriMetric TM-2020 or TM-2B meter for 48 volt operation. It will also provide excellent lightning protection at any operating voltage from 12 to 48V. With the protector installed as described here, the TriMetric warranty will extend to cover lightning damage. This adapter is designed to mount next to the TriMetric terminal block to which the wires to the battery are connected. It is not recommended for use with the older type TriMetric TM-1B, with its smaller steel cover, because although it will work electrically and protect the meter, the cover will not fit on the meter when the adapter is installed. A slightly different adapter is available (TM-48V) which may be used with the TM-1B.


Lightning protection specIt is designed to absorb lightning induced transients with 100 Amp max. surge current (8 ms rise/100 ms decay time). Under these conditions voltage may rise at the input to 200 volts for up to 1000 ms. (This is a conservative rating.)
Maximum/minimum voltage allowed to adapterThe minimum and maximum system battery voltage which may be placed to the adapter depend upon whether it is configured for 12, 24 or 48 volt systems. (See step 1 on reverse.) Too high voltage will damage the unit; the voltage rating should not be exceeded, even for short time (except for the very short lightning transients mentioned above.) Too low voltage will not damage the unit, however the TriMetric may not function properly.
12 volt configurationmin. 8 volts, max. 18 volts.
24 volt configurationmin. 12 volts, max. 50 volts.
48 volt configurationmin. 12 volts, max. 70 volts.
Power requirement Requires less than 1 ma.
