The M3628PCT is designed for testing capacitor banks. Electrolytic capacitors
undergo physical changes when stored for long periods. Depending on the ambient
conditions of the storage, this can be from six months to two years. If the capacitors are
rapidly taken to their rated voltage, excessive leakage current may cause them to
overheat and fail.
As capacitors age and wear, their internal chemistries change, leading to changes in
their capacitance. It is important to be able to measure this capacitance, and thus
estimate the remaining useful life of your capacitor bank.
The Bonitron M3628PCT is a portable digitally-controlled capacitor tester. The digital
display allows the user to charge a capacitor bank to a specified voltage, and then
discharge the bank. The display will then show the calculated capacitance of the bank.
This product may be used for many purposes, including charging, discharging and
forming of capacitors, as well as serving general DC power needs.
