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.
Specifications
|
Lightning protection spec |
It 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 adapter |
The 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. |
