RIVE PTIONS In 1975, Bonitron began working with AC inverter drive specialists at synthetic fiber plants to develop speed control systems that could be interfaced with their plant process computers. Ever since, Bonitron has developed AC drive options that solve application issues associated with modern AC variable frequency drives and aid in reducing drive faults.
URPOSE AND COPE This manual is a user’s guide for the Model M3628PUT. It will provide the user with the necessary information to successfully connect and operate the M3628PUT. In the event of any conflict between this document and any publication and/or documentation related to any associated hardware (capacitor bank, etc.), the latter...
M3628PUT 1.4. YMBOL ONVENTIONS SED IN THIS ANUAL AND ON QUIPMENT Earth Ground or Protective Earth AC Voltage DC Voltage Electrical Hazard - Identifies a statement that indicates a shock or electrocution hazard that must be avoided. DANGER! DANGER: Identifies information about practices or circumstances that can lead to personal injury or death, property damage, or economic loss.
User’s Manual RODUCT ESCRIPTION EATURES The M3628PUT is designed for testing of ultracapacitors. As ultracapacitors age and wear, their capacitance decreases, and their ESR increases. This can result in decreased system performance, and ultimately, process failure. Measurement of an ultracapacitor's capacitance and ESR can help avoid expensive preemptive replacement.

NSTRUCTIONS 3.1. NVIRONMENT While closed, the M3628PUT 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.
3.2.3. ONSIDERATIONS To ensure the most accurate possible measurements, the capacitor under test should be charged to its full rated voltage. Note that the M3628PUT will discharge the attached load capacitor to 2VDC. This unit is thus not recommended for use on ultracapacitors rated at less than 5VDC.
UNCTIONAL ESCRIPTION The M3628PUT is a digitally controlled DC supply capable of sourcing between 1 and 7 amps at between 0 and 130VDC. The unit is powered by standard 50-60 Hz AC. The output voltage is controlled by the digital interface panel on the front of the unit.

User’s Manual 4.3.1.1.6. HARGE ROFILE ONFIRM At this screen the user is asked to confirm the Profile settings. Enter will start charging. Cancel will abort charging. 4.3.1.1.7. XECUTING ROFILE This screen displays the present output voltage and current and seconds left for each step. It transitions to the "Discharging" screen (4.3.1.2.6.) when the output voltage reaches the set point and is held for the specified number of seconds.
Check the polarity of the leads attached to the ultracapacitor under test. 4.4.4. This fault indicates that the fuse in the charging link of the M3628PUT has failed. Power down the unit and replace the fuse with one of comparable specifications (Section 5.1).

A short description is below. Ensure the capacitor bank is fully discharged and floated. Apply power to the M3628PUT. Attach the output leads to the capacitor bank directly. If you are forming the capacitors in a drive, ensure that you are directly across the DC bus, not attached through the braking circuit.

M3628PUT connecting the load. Record the calculated capacitance and ESR somewhere safe, along with the designation of the capacitor being tested. Multiple tests may be performed if desired, to ensure repeatability. Once the procedure is completed successfully, the capacitor bank or equipment can be returned to storage or put into use, as appropriate.
