As ultra-capacitors age and wear, their internal chemistries change, leading to a decrease
in capacitance and efficiency. It is important to be able to measure capacitance and
equivalent series resistance (ESR), and thus estimate the remaining useful life of your
capacitor bank or constituent cells/modules. This can help reduce expensive pre-emptive
replacement. Capacitors stored for long periods of time also display chemistry changes,
which gradually reduces capacitance and increases ESR.
The Bonitron M3628UCT is a portable, digitally controlled DC power supply and capacitor
test system with a variable output voltage and current limit. It can perform accurate,
informative measurements of an ultra-capacitor's capacitance and ESR. This product may
be used for many purposes, including a general purpose voltage/current source, charging
and discharging capacitors, and measuring capacitance and ESR.

The M3528 charger can charge strings of batteries or ultra capacitors to voltages
required for industrial and commercial applications. AC or DC input is available, along
with separate float and equalization charge levels. The charger is current limited, and
designed for use in integrated storage and backup systems, but can also be used in
bench or mobile systems.
KIT 3628T U
Large capacitor banks store huge amounts of energy, and can be a hazard when
systems are shut down for system maintenance. The KIT 3628T system discharges
capacitor banks to safe working levels quickly, allowing work on the system to begin
in seconds, rather than hours.
M3628PCF P
The M3628 portable capacitor former can be used to charge or discharge capacitor
banks as large as 50 kJ. The output voltage is manually variable between 0 and 800
VDC, and the system is capable of supplying 1 ADC continuously. The unit can also
be used for reforming disused capacitors.
M3628ACF A
The M3628ACF automatic capacitor former can be used to reform capacitor banks as
large as 150 kJ. The output voltage is programable between 0 and 1000 VDC, and is
capable of supplying 1 ADC continuously.
