Page 9: Roduct Escription
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. -

NSTRUCTIONS 3.1. NVIRONMENT While closed, the M3628UCT is water, dust, and crush resistant. When open and in operation, the unit should be used only in dry, clean areas. Ensure that the interior of the unit casing is kept dry. 3.2. -
Page 14: Source Considerations
M3628UCT 3.2.2. OURCE ONSIDERATIONS Input voltage should not exceed the rating—120VAC or 240VAC depending on model—or damage to the unit may result. To guarantee correct system operation at all output voltages, the source must be capable of supplying at least 10 amps for 120VAC supply or 5 amps for a 240VAC supply. Failure to meet the minimum current requirement may result in improper operation. -
Page 15: Operation
UNCTIONAL ESCRIPTION The M3628UCT is a digitally controlled DC supply capable of sourcing and sinking 1 to 30 amps between 2 and 20VDC. The unit is powered by standard 50-60 Hz 120VAC/240VAC. The output voltage and current is set by the digital interface panel on the front of the unit. -

M3628UCT DC O 4.3.2. UTPUT AND EASUREMENT ONNECTORS Four PowerPole connectors provide the user with DC output voltage between 0 and 20VDC, a charge/discharge path for the current to and from the capacitor being tested, and precision Kelvin measurements for ESR. The standard cables shipped with the system include either two high-current alligator clips or ring terminals, and two measurement clip leads. -

ROUBLESHOOTING If a problem occurs on start-up or during normal operation, refer to the problems described below. If a problem persists after following the steps below, contact Bonitron Tech Support, the product supplier or your system integrator for assistance. Repairs or modifications to this equipment are to be performed by Bonitron approved personnel only. - Page 26 • Check the output voltage with a separate voltmeter. If the voltage Red voltage present light never turns on regardless of is above 2VDC, your unit may require service. Contact Bonitron. output voltage Always monitor the output voltage while operating the unit. Ensure that the attached loads do not exceed their rated voltage, as catastrophic damage, injury, or death may occur.

Page 29: Application Notes
A short description of how to use the M3628UCT to test a capacitor cell or module is given below. Ensure the capacitor is discharged. - Page 30 M3628UCT If the bank is put into service, test the capacitor bank periodically, on a schedule recommended by the capacitor manufacturer. Ensure that all tests are performed in a similar ambient temperature; otherwise comparison between results may not be valid. If over time the bank capacitance falls below the manufacturer- recommended percentage of the original recorded capacitance, discard and replace the capacitor.
