Q: How expensive is the unit?
A: Flywheels typically costs 2-4X the initial cost of batteries, but
considering batteries last only 3-5 years and batteries require significant
maintenance, the flywheel solution is a much more attractive solution
over the life of the UPS.
Q: Does the unit need to be bolted down?
A: Yes, each unit ships with the hardware necessary.
Q: Can the unit be installed in a (Seismic) Zone 4 environment?
A: Yes, we plan to have it evaluated and have OSHPD certified.
Q: Can the unit be installed on a raised floor?
A: Yes, a floorstand may be used to accommodate the unit.
Q: What safety, EMI and other agency certifications do you intend
to have?
A: We are now in the final stages of UL and C_UL for safety. We also
intend to market the product in Europe, so we will be pursuing CE, in
which case EMI evaluation will take place.
Q: Is a vacuum pump necessary?
A: Our flywheel requires a vacuum pump. We use either an Alcatel or
a Pfeiffer pump that are both very high quality. The vacuum pump does
require the oil to be changed annually to keep it in good working condition.
Q: What is High/low cycle?
A: High/Low cycle refers to the specific use of the product. High cycle
applications are where the product is cycled often, multiple times per
day. An example of this would be in rail applications for voltage support
and energy recovery at rail substations where the product cycles whenever
a train arrives or departs (possibly a cycle every two to three minutes).
Low cycle applications would be your typical UPS application, where
the product goes through less than 100 full discharges per year. The
unit may experience frequent short discharges, but infrequent full discharges.
Q: Is VYCON’s product a complete UPS solution?
A: No, the output of our Flywheel product is DC only. We do not provide
the AC conversion, a UPS is required.
However, because 98% of fatal power quality events last less than 15
seconds, the Vycon product can completely replace battery banks when
used in conjuction with a standby generator and prevent short cycling
of the genset. If longer backup time is required without a genset, the
Vycon system can cover 98% of the power quality events, thereby saving
the batteries for the longer term events (battery hardening). This setup
will prolong the life of the batteries and more easily provide high
short event surge currents. For some applications, 98% coverage is sufficent
and do not require a genset or battery banks.
